  1. The slim speaker in the Spendor line is the A2 with a 150mm mid-bass instead of the 180mm in the A4, A7 and D7. Has anyone heard these? A 150mm mid-bass may favour the mids and go some way towards the Harbeth there? A pair for £1199 on ebay......
  2. Haha..... yes, once you go above 2-ways the picture does change. The easy answer is, as you say, that there are good and bad examples of both. But a sealed box remains an ideal for some. For the BBC I imagine they wanted the speakers to be used in confined spaces including up against walls, though a front port would have been possible with a different design. So presumably a sealed box was thought to have virtues. For ATC a sealed box was a design decision, and they are pretty good at designing speakers. So the question is a valid one. Here's an interesting site to read up on this: https://audiojudgement.com/sealed-enclosure-closed-box/
  3. We have some excellent threads going on 2-way speakers, and part of the discussion is around sealed versus ported boxes. The discussion ranges from the BBC LS3/5a which is a very small sealed box to the ATC SCM11 which is 20 litres in external dimensions. If we consider "bookshelf" 2-ways to have a mid-bass from 135mm to 150mm could the discussion include floorstanders with similar units? Some have stated that they will not use ported boxes for sonic reasons. Others are more open to persuasion. There is a huge knowledge of 2-way speakers here, so what are you guys finding on this issue?
  4. Just to clarify - what "interconnects" are we talking about here, speaker cables, RCA interconnects or both?
  5. Hmmm.... from your choice of music and desire for musicality I would have gone straight for panel speakers. But from the above I'm not sure where you would situate them. Nevertheless, I suggest looking at Quad 57s, and used Martin Logans, Magneplaners and even better a pair of Apogee Caliper signatures if you are lucky enough to find them. Apogee spare parts can be sources from Australia. There is also Newform in Canada for ribbons but that would be more complicated.
  6. Well, actually yes. I don't have any fancy cables at all and not going to buy any. However, I do need to make some good DIY interconnects with RCA plugs. Not fussed about the plugs, but I would like some recommendations for good cable to make up the interconnects with. So off you go, lads......
  7. I just measured my listening room and it's 14'9" by 11'1" (4.5 x 3.38 m2). This looks like a pretty ideal room size for these kinds of bookshelf speakers. I haven't looked into room nodes. Can anyone comment on room sizes and speaker interaction?
  8. Ported speaker versus sealed boxes is a pretty fundamental argument. I agree that sealed boxes have a generally better sound, though that's not always the case. The question is how do you keep the midrange pure and still get "enough" bass. It's partly about making a choice between a 5", 5.5", 6" or 6.5" midbass. The bigger you go the more you may compromise the midrange. The smaller you go the more you may compromise the bass response. Et voila!
  9. That's exactly what I did - got a pair of early Wharfedale Diamonds. They sound remarkably good for the cheap price I paid - usually around £50. They were ex BBC - the BBC used them in their offices. I may upgrade them at some point but I'm in no rush. For me it's all about the amplifier and getting that right. For me a 2a3 or 300b SE tube amp and a pair of small 2-way speakers is a magical combination. As others have said - it's all about that "you are there" midrange, and vocals are special as we know.
  10. My room is just slightly bigger than yours and I use early Wharfedale Diamond 2-way speakers. I really like them. I drive them with a single ended 2a3 tube amp. They are bass reflex, and I find the bass quite adequate. The midrange is wonderful and that's what you get with a 2-way and a really good tube amp. I have no desire to go to a bigger speaker, and in any case I don't have the room, so I'm more than happy. My question with an LS3/5a would be the bass extension, since it's a sealed box. The midrange will probably be very good, and again if it were me I would use a tube amp like a 2a3 or 300b to really get that magical midrange. But I think I would be looking for.a more modern design with better units and a reflex port. Plenty of information on LS3/5a and shootouts on YouTube etc etc. and that's the conclusion several reviewers come to. I haven't heard a LS3/5a in my system so I don't know what bass you would get - I'm sure others would advise. I wouldn't use a sub myself, I'd be happy with the right kind of 2-way. Keep it pure and simple.
  11. OK, the only double album I remember owning was Dylan's Blonde on Blonde - that was good but probably before the 70s.
  12. I don't have vinyl - sold it all. But I do have double and triple CDs in my opera collection. So my best picks... - Janacek The Cunning Little Vixen on Supraphon - Wagner Die Meistersinger, Solti (2) on Decca
  13. If the GZ34 is rated by Mullard standards - pretty tough - then a substitute may be over-stressed. But as said above, the 845s will have solid state rectification so if they went out the trouble might be upstream of the GZ34. When and if you get the amp back, check to see how much the GZ34 is stressed and which versions are as tough as a Mullard.
  14. That's an interesting piece of 19" rack mounted units. What is it? Is this a recording studio?
  15. In my case it's 2 tubes. - the type 26 DHT literally made my jaw drop the first time I heard it. I think I must have said out loud "this is what I've been looking for for years". This started me on collecting DHTs and I have hundreds now. Too many, and I'm selling them bit by bit. - many years later I came across another wonderful DHT - the Russian 6C4C, a 2a3 type with 6.3v filaments. I use it as outputs in preference to 300b. And a couple of weeks ago I decided to try it as a preamp tube and was astonished to find I like it so much I added it to my system. And I don't even use a preamp. Well, I do now. It's detailed, transparent, dynamic and really makes music come alive. And strangely almost nobody builds a 2a3 preamp or even talks about it. Well, it's on my map now and staying in my system. A truly unexpected discovery.
