  1. Sounds promising, do you or anyone else have a way of contacting him?
  2. Anyone got a recommendation for someone who can do a quick job on a Quad? I like in Wimbledon and I'd like to be able to just drop it off to them. Taking it to Quad in Cambridge basically takes the whole day so if there's a possibility nearer then I'd prefer it. It's a 520, dead in one channel.
  3. About 10 years ago I talked to Quad about the right size amp for my ESL 63s, at the time I was using a Quad 303. They said that if I used a more powerful amp I may notice a difference on the attacks of notes, the start of the note. I duly upgraded to a quad 520 and it made a difference though I’m not sure it improved things. Now I’ve learned that I prefer the sweet sounding 303 to the 520, though I’m not using either with the quads. At at the moment I use an Electrocompaniet ECI - 2 with the ESLs (they are with Gradients, so I guess that means that the Electrocompaniet has less work to do) The setup sounds very good . . . but not good enough. It has presence, with a big 3D image, but the image isn’t as firm and airy as in the Spendor/Krell system, which captures more of the details of voice and instrument separation and placement. Like Bencat I have a Mk1 Krell KSA50, which I’ve been assured delivers about 75W per Chanel Class A. This sounds fabulous in a system with Spendor SP 1s, better than the Quad system for imaging. I intend to swap the amps soon (it weighs 30kg, so to lift the Krell around is a pain!), No preamp in all cases; volume control digital through the Logitech Media Server; Theta and Museatex DAC with Spendors and ESLs respectively,
  4. Quad 34 serviced by Quad with box £225 plus postage.
  5. To be got to me in London.
  6. I really want these but I just don't have the room. Please do not tempt me.
  7. I'll need to get it to my house in London.
  8. To be delivered to me in London.
  9. I may be interested in the amp, but not the speakers. And we'd have to find a way to get them to London! But that will be possible. Can anyone find any info for me on the amps. What is class AA? How powerful are they? How much do they weigh etc.
  10. I believe that Class A amps draw full current at idle. And the maximum theoretical efficiency is 50%, in reality probably much less. I have one of these amps, it doesn't get hot enough and it's not heavy enough for 50W Class A. There's no fan. I can touch it without burning my hands. It doesn't heat the room much in winter.
  11. 70W for a 2 x 50W O/P into 8 Ohm does not suggest class A all the way to max output.
  12. Rogers JR149 with brackets, I have them mounted on a wall driven by a 50W amp and they're good. You'll be able to get a pair for around £400 from ebay, and I noticed a pair of brackets on there the other day for £40.
  13. Does anyone know if this runs in Class A up to a certain point? If so, at what point does it switch to Class B?
