  1. How is that gorgeous? It looks like something you might find in Frankenstein's laboratory! I would want that in my living room. It would be challenging even for a Man Cave.
  2. Which 'a car dealership' are we talking about. Google Maps seems to find thousands of them!
  3. I've been enjoying an Edge A2-300 for about 18 months or so. It's part of my PC/AV rig fed by an RME ADI-2 DAC and driving Mark Audio SOTA Cesti MB. I've had a few speakers in here whilst using the XTZ and it drove them all superbly - Rogers LS4a, Celestion 3, JPW Gold. Great bass. Great transparency and soundstage. Fast and unflinching. Outstanding for the price. Superb with movies too. Surprising bass from the Cesti MB. No sub needed.
  4. They look like Sonata to me. Different bass driver to the Mini Monitor and Gold. The Gold also had an exposed dome tweeter, not the propeller phase plug tweeter.
  5. I have a pair of MSR7. I find them a little mid-forward. They did not make a good pairing wih the Arcam rPAC which is also a little mid-forward. They sound good with an iCAN and of course with ADI2-DAC you can make them sound however you want. The only other thing that bugs me personally is the narrow headband. Being of the bald persuasion, I prefer wide headbands. A good headphone for the money though. They have a strong following on Head-Fi. I should really get around to selling mine as I don't use them now.
  6. For me, that perfect partner seems to be the T1 (original). I go to the show every year and listen to such others that are available which is quite a few from Sennheiser, Audeze, Focal, Fostex, Audio Technica and others. The only one that really piqued my interest was the LCD-X which souded great with the top iFi Pro system so when the cheaper Creators Edition appeared, I took a chance on a pair. They are excellent headphones but I think I still prefer the T1. I also have a T5p for use with the desktop computer which is not a silent model and I enjoy those too. I would be lost without EQ on all of them because my music collection spans many decades and tastes and the tonal balance varies widely. The T1 sometimes needs a little extra bass. The LCD-X often needs extra treble. The T5p can be a little mid-foward sometimes. The T5p is used with the RME ADI2-DAC which is the hub of my combined computer and AV system and also drives speakers so EQ'ing is very easy. I highly recommend the ADI2-DAC - more so since I added Resampler-V to foobar2000 to upsample on the PC instead of in the DAC. The T1 is used with the iFi iDAC2 and iCAN. The two position XBASS switch does all that is required in the bass with the T1. This also benefits from the Resampler-V treatment and goes toe-to-toe with the RME. The LCD-X benefits from the 3D Holographic setting on the iCAN which adds a little more top end and opens them up a bit. Both systems are using iPurifier2/iPurifier3 which yields even more transparency and separation. I have a pair of Audio Technica ATH-MSR7 sitting in a drawer somewhere that don't get any head time since I got the T5p and LCD-X. Nice phones which have a dedicated following on Head-Fi but not quite in the same league as these others. I really should move them on.
  7. Sounds like you both need the Focal Stellia. Sorry for your wallets :-)
  8. This page: Even in that worst case scenario, the noise spectrum is down around 100dB. If it were not, no-one would ever listen to NOS. It would sound terrible.
  9. Fortunately the rise time needed to reproduce those steps is not available from most tweeters or headphones, nor human ears, nor indeed many amps, so what you end up hearing is actually pretty smooth. The distortion introduced by NOS may be much worse than with filtering but it is still below 100 dB and therefore in the noise floor for CD audio. Nobody would listen to it for long otherwise.
  10. Indeed, I have been listening to the RME NOS filter for some months now (in the belief that it must be better because there is no ringing, LOL) and I don't notice the roll-off very much if at all. It's only 3dB down at 20 kHz after all. That's not much. Plus I'm rapidly (too rapidly!) approaching 60 so I can't hear the top half of the top octave much anyway.
  11. Well now, what a useful thread this has turned out to be. I now know far more about oversampling and digital filtering than I did before. Seems that, like so many others, I have been worshipping some naked Emperors without really knowing why. I am very happy that I can now stop worrying about 'ringing' as it only occurs with badly mastered 'loudness wars' CDs that have far worse problems than a little bit of ultrasonic noise! With all this new knowledge in mind, I set about doing some experimenting to see if I could really hear any differences between the filters on the ADI2-DAC (using T5p, T1 and LCD-x). I have to confess that with properly mastered red book material, I could not really discern any reliable difference. Ho hum. Then something Archimago wrote got me thinking about trying resampling on the PC instead of in the DAC so I did this: 1) Set the ADI2-DAC to "NOS" filter 2) Add the Resampler-V plugin to foobar2000 (needs VST plugin) 3) Upsample 44.1kHz tracks to 352.8kHz using SoX, 91% passband, mirrored stop band, pure linear phase 4) Upsample 48kHz tracks to 384kHz using SoX, 91% passband, mirrored stop band, pure linear phase The result was surprisingly audible! I really didn't expect it to be. I expected this would be more of listening for vanishing small details, more inky blackness, etc. - all very subtle. Alas, no. This turned out to be one of those cases where you don't hear that something is not quite right until that not-quite-rightness is taken away. The sound is purer, easier to listen to, better defined. A certain rough edge on certain instruments, certain voices, where I am used to bracing for impact, has disappeared. It seems to have lost nothing in terms of the sacred 'musicality'. It's just as involving, more so in fact. The sound now easily matches what I used to get out of my Audiolab 8200CDQ where it didn't quite manage that before. Until this, I thought I was just missing something that only Sabre DACs do. The reason? No idea. Is it the interpolating algorithm? Is it the filter? I really don't know. I repeated this experiment on my other system with the fanless laptop and the iDAC2 and got the same result. The iFi now sounds as good as the RME and they both sound better than before. I'm so glad I found this as I was about to pull the trigger on an expensive Sabre DAC to get that sound back again. No need now so thank you all for that.
  12. For £100, you could get a Bluetooth adapter from a known brand with LDAC, a known high-end DAC chip, great sound and a free DAP into the bargain. I am talking about the Shanling M0. It's a DAP that can take a 512GB micro SD card. It contains an ES9218P Sabre DAC with Hyperstream. Battery life is 15 - 16 hours playing FLACS. It can both transmit and receive Bluetooth with LDAC (not both at the same time) and has a LINE OUT mode. I have one and I love it.
  13. I have spent many months slowly examining all the PMP options out there. I bought another Clip+ and a £128GB micro SD card. I found the Clip+ cheapest direct from My Memory. The genuine Sandisk 128GB micro SD cards direct from Amazon were reduced to £34.99 last week.
  14. I owned Zu Druid MkIV for 3 years. I loved them. They are fantastic. They sound more real than any other speaker I've heard before or since. On the end of an Audiolab 8200CDQ and a Croft Integrated, they were never fatiguing. They are fast with good impact. They sound like real musicians playing real instruments in your room. Most other speakers sound broken after a few hours with the Zu's. I'm a headphonista now but if I ever get the chance to use big speakers again, a new pair of Druids will be top of the list - probably the only thing on the list.
  15. It can be fairly said that you need a fairly high quality amp and speakers/headphones before you need to start worrying about noise on the USB input. If you upgrade to an iFi Audio micro iDSD, this has an iPurifier built in and seems to be completely agnostic to the driving source. Good comment about tuners Paul (you scamp)
