  1. For sale is my Audioquest Castle Rock speaker cable. This is a 5m single bi-wire version with spade connectors at the amp end and spades and bananas connectors at the bi-wire speaker end. I bought this ex-demo from DB Hifi (an Audioquest dealer) and can pm original receipt if required. The condition is excellent. They didn't come with box or other packaging, but I will package them securely for shipment to the UK. Item location is Kinross, just north of Edinburgh and you are welcome to collect, covid permitting. Prefer bank transfer or Paypal Friends payment. These currently retail for £2,149. I am looking for £1,050 including insured courier shipping within the UK. Audioquest cables have a great reputation and these were a significant upgrade to the sound of my system, particularly for bass and transparency. See reviews and description below: https://www.hifiplus.com/articles/audioquest-earth-castle-rock-and-nrg4-cables/ https://www.hifitoday.com/audioquest-castle-rock-water-and-yukon-cables-review/ Castle Rock About DBS RIP Gibraltar, long live Castle Rock! Like Gibraltar before it, Castle Rock is designed as an extremely high-performance cable which provides true Double-BiWire performance in a single attractive cable. Original Gibraltar’s all important basics – superior geometry, magnetic autonomy of each quad-conductor section, Perfect-Surface metal technology, conductor-size optimization (AQ’s Spread-Spectrum Technology), etc. – are the fundamentals of Castle Rock. Castle Rock employs AQ’s best copper conductor metal (Perfect-Surface Copper+), AudioQuest’s DBS (Dielectric-Bias System) and NDS (Noise-Dissipation System). A very recent advancement featured in Castle Rock (and all other Tree and Rock Series speaker cables) is the addition of the sleek new “Hanging-Silver” 1000 Series Multi-Spades and Bananas. Originally developed for the WEL Signature Series speaker cables, these plugs are made using a “hanging silver over pure red-copper” process in which the spades and bananas are submerged (“hung”) into a vat of extreme-purity silver, resulting in a very thick direct-silver plate. No intermediary performance-degrading materials (such as nickel or alloy) are used. Also new to Castle Rock is a more-neatly-sculpted “breakout” (the covering where the cable separates into red and black legs), which is now made of a synthetic non-magnetic polymer, rather than metal. We’re making this all-models upgrade because speaker cables and AC power cables carry large magnetic fields which interact with any metal “collar” around the cable. Eliminating metal in the breakouts is another significant (and clearly audible) step forward in our goal of eliminating distortion and making the cable sonically “invisible.” Please note too that AudioQuest now offers a Single-BiAmp option for any Rocket, Rock or Tree Series speaker cable, including Castle Rock. Although similar to a Single-BiWire configuration in which the speaker end has four connectors, the Single-BiAmp configuration also has four connectors at the amplifier end to accommodate the growing number of users who wish to take full advantage of all the amplifier channels in many of today’s AV receivers and multichannel power amplifiers. Castle Rock represents the culmination of Gibraltar’s long-term evolution along with performance- enhancing new systems and materials. These ingredients add up to important audible improvements and more pleasurable listening! SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS: Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Copper+ minimizes distortion caused by grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers. CARBON-BASED NOISE-DISSIPATION and CROSS-TALK-DISSIPATION SYSTEMS (INSULATION): The negative conductors in Castle Rock are insulated with partially conductive Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency garbage from being fed back into the amplifier. The sonic benefit is exactly the same reduction in “hash” and better dimensionality that comes whenever RF garbage is reduced in an audio circuit. Castle Rock uses Nitrogen-Injected Foamed-Polyethylene Insulation on its positive conductors because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials. DIELECTRIC-BIAS SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1): All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest’s DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check. DOUBLE STAR-QUAD GEOMETRY: The relationship between conductors defines a cable’s most basic electrical values (capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly affect the sound. The Double Star-Quad construction of Castle Rock allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel. SPREAD-SPECTRUM TECHNOLOGY (SST): Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid or tubular) have the fewest discontinuities, any conductor of a particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. The different SST-determined conductor sizes used in Castle Rock allow an exceptionally clear, clean and dynamic sound. BIWIRING: Castle Rock is an exceptional Single-BiWire cable. When the halves are separated at the speaker end, the Double Star-Quad Geometry turns Castle Rock into a true Double-BiWire set thanks to the magnetic autonomy of each Quad-conductor section. On its own, one Star-Quad conductor group would be a little lightweight in performance as it is biased towards treble finesse. The other Star-Quad conductor group is biased toward the bass; it’s more forceful and lacking ultimate resolution. Together they form a completely optimized full-range design. When separated, the Double Star-Quad design allows Castle Rock to be a maximum-performance Double BiWire in a single cable. TERMINATIONS: AudioQuest offers a wide range of high-quality connectors that allow Castle Rock to be securely attached to any type of equipment. Quality is in the low-distortion sound, not necessarily in the eye-candy effect. AQ ends are either dull looking gold or silver because these metals are plated directly over the connector. There is no shiny and harsh sounding nickel layer underneath. AQ PK-spade lugs are soft because better metal is soft, and facilitates a higher quality connection. For pieces requiring a banana plug or BFA connector the AQ PK-BFA/Banana provides unprecedented performance over conventional brass versions. APPLICATION: The ABS breakouts on either end of Castle Rock are marked “Speaker End” or “Amp End.” Please use cables in the direction required.
  2. I'm having a cable and kit clear-out. Selling three Audioquest interconnect cables: 1 x Audioquest Earth, 0.5m, Balanced XLR Interconnect, £385 I bought these ex-demo from Audio Emotion, an authorised Audioquest dealer. Comes complete with all original packaging - box, protectors and a rather natty carry-case. Condition is excellent with the only minor fault I can see is a bit of fraying to one of the cable ends and some very slight tarnish to some connectors (I haven't bothered to clean, but from various web threads seems like a simple job for whoever buys). These currently retail new for £769, looking for £385, plus UK postage. 1 x Audioquest Yukon, 1m RCA interconnect, £195 Bought new from Audio Emotion, an authorised Audioquest dealer. Comes complete with all original packaging - box, protectors and protective plastic sleeve. Condition is excellent (as new). These currently retail new for £389, looking for £195, plus UK postage. 1 x Audioquest Columbia, 1m RCA interconnect, £185 Bought pre-owned from Audio Emotion, an authorised Audioquest dealer. Comes complete with original packaging - box and velvet carry-bag. In great condition. These retailed new for around £400, looking for £185, plus UK postage. Audioquest cables have a great reputation and these were a significant upgrade to the sound of my system.

  3. Ordered a range of PRP metal film resistors from 75K to 160K from Hi-fi Collective. They are only 38p each so very cheap way to experiment with the sound. Thanks again.
  4. David Beetles forwarded my query to K S Park, founder of Allnic. He replied immediately confirming that the stage is open and I can use a 75K or above resistor for my cartridges. Very impressed with the service from Allnic. My query went from the UK to Canada to South Korea and was answered within 10 hours on a Sunday! Now looking to source some resistors as per the advice from Wammers on the DIY forum. Thanks again.
  5. Thanks James. I posted my question on the 2 Channel forum and Rabski has pointed out that the Allnic may be constrained by being "fixed" at the 47K ohm MM standard loading. In which case I can't swap in resistors beyond 47K. I have written to an Allnic distributor to check. If I am able to go beyond 47K, then splitting the difference and getting a 125K seems sensible. You advised laser trimmed metal foil. From your experience, are there any particular brands or UK web stores that I should be looking at? Cheers, Craig
  6. Thanks for the response, Richard. I think you are right and the key question is whether the Allnic is fixed at a standard MM loading of 47K. I suspect it might be, or presumably they would have supplied more resistors beyond 47K as an option for higher loading carts? I have sent off a query to David Beetles of Hammertone Audio, who is the Canadian distributor for Allnic and seems to be the global guru on technical questions (I couldn't find a direct contact in S. Korea from the Allnic website). I have been using the Brinkmann EMT Ti and it sounds alright, but isn't a great improvement on my Remton 383 MkII phono stage which is a quarter of the price. The Remton is a great unit, but I think I was expecting a larger improvement from the Allnic which hasn't really materialised yet. Out of interest, if the stage does have a standard impedance of 47k, what would happen if I swapped in a 100 or 150 K resistor as a secondary load? Would it cause any damage to the unit, would it just not work or would it just sound awful? Cheers, Craig
  7. I've recently bought a pre-owned Allnic H1500 II Plus and I am looking for help from anyone who has experience changing resistors beyond the pre-supplied 47k ohms, to increase cartridge loading. Allnic supply 5 different resistors which range from 4.7K to 47K. The Turn Ratio of the SUTs is adjustable between 13, 20, 26 and 40. Using these together offers a range of loading from 3 ohms to 278 ohms - see Allnic impedance table below: Allnic H1500: Impedance Combination Table T /R1. S * R2. 1 / 13 +22dB 1 / 20 +26dB 1 / 26 +28dB 1 / 40 +32dB 4.7 K ohms 28 ohms 12 ohms 7 ohms 3 ohms 10 K ohms 59 ohms 25 ohms 15 ohms 6 ohms 20 K ohms 118 ohms 50 ohms 30 ohms 12 ohms 30 K ohms 177 ohms 75 ohms 45 ohms 19 ohms 47 K ohms 278 ohms 117 ohms 70 ohms 29 ohms 1. Turn Ratio of Step-up Transformer 2. Secondary Load Resistor The problem I have is that both my MC cartridges require loading far beyond the upper range of 278 ohms. I have a Brinkmann EMT Ti Cartridge with a recommended loading of 600 ohms and a Benz Micro LP S which generally loads between 500 and 1000 ohms (see specifications for both below). I have no electronics knowledge, but hopefully with a bit of common sense and using a loading table from the web (http://www.mh-audio.nl/Calculators/StepUpTransformer.html), I have worked out I need a 100K ohms resistor for the Brinkmann EMT (giving a loading of 591.7 ohms) and a 150K Ohms resistor for the Benz Micro LP S (giving a loading of 887.6 ohms). However, beyond that, I am a bit lost. There seems to be multiple types of resistors (carbon, metal, film, wire-wound, etc.) then they each have different power ratings, voltage ratings and tolerances. I am afraid that I may end up blowing the stage if I install the wrong component. My integrated amplifier is a Perraux 250i and my turntable/arm is a Brinkman La Grange/ Brinkmann 10.5. Can anyone on the forum help/advise? I am not sure if this is a 2 channel or a DIY topic, so I am posting in both.

  9. E-bay auction ends at 20.00 tonight. Starting bid is £1500, so grab yourself a bargain...
  10. EMT in Switzerland have replied with refurbishment details: There are two offers of refurbishment: Repair I This is applied if the diamond is used up or the cantilever is broken or bended. The complete transducer unit and coil are replaced. Cost is CHF 1’400.- Repair II This is applied if the cantilever and diamond are in good shape. The suspension and – if needed – the coil is replaced. Cost is CHF 500.-. Prices are understood excluding transport and VAT. This works out to be c.£1,300 (Swiss VAT is 7.7%!) for Repair I, the full refurb. This is just under 50% of the new price for the Brinkmann EMT Ti (£2,650 in UK). I've told them I would like to go ahead and will be shipping the cartridge to them on Monday. While it is away will contact some dealers to see if I can start demoing the other cartridges.
