    I really want these but I just don't have the room. Please do not tempt me.
  3. I'll need to get it to my house in London.

    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.

    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.

    70W for a 2 x 50W O/P into 8 Ohm does not suggest class A all the way to max output.

    Looking for advice on bookshelf speakers that can be wall mounted

    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.

    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?
  10. This pre-amp looks extremely stylish. If you have never heard one you're in for a treat because it is so much more than a regular pre-amp. It boosts low frequencies in small speakers, so you don't need subs. And it lets you keep your equipment close to the back wall without creating boomy bass. It compensates for poor source material and it even allows you to change your perspective, so you've always got the best seat. This Quad 34 is rightly famous for its controls, which may never have been bettered. The BASS LIFT control does the best job I've ever heard at low-level loudness compensation. It also compensates well for smaller loudspeakers, acting as an electronic subwoofer, boosting only the very lowest bass without altering the mid- and upper-bass. The BASS STEP control removes bass boom or bloat caused by placing loudspeakers too close to the wall in a small home. The smooth HF filters eliminate high-frequency zing or distortion. The TILT control allows the listener to choose his own seat in the hall. I have the receipt for the Quad service. Everything is working fine, just no longer needed. The box, Quad's own box, made to measure, wraps it in incredibly thick packaging, so you know that nothing will happen in transit. Loads of pictures here Small chip on volume control and light marks to the top. I never noticed until I got it out today to sell. Priced to sell -- £225 plus any postage. You are welcome to collect from London (SW19)
  11. Does the sound quality deteriorate as the capacitors deteriorate? Do properly restored amps sound better? Is an older unserviced amp more likely to go DC? Does a stitch in time save nine? I mean, are you more likely to save yourself an expensive or even impossible repair if you get it serviced?
  12. Mine is over 20 years old, it naturally runs hot, and as far as I know it has never had any capacitors replaced. It sounds fine, but for all I know isn't performing at its best. Do I let sleeping dogs lie?
  13. I want to revive this thread to see whether the feeling of people here is still the same -- which in 2012 was, leave old solid state equipment alone until problems start to show up. I'm especially interested for amps which naturally run hot (class A)

    FOR SALE - MARANTZ PM4 Integrated Class A Amp

    Marantz had a technique called "Quarter A", where bias current was adjusted such that Class A power reached 25% of maximum power output. In a 100 Watt amp, that means the amplifier deliver the first 25 Watts in Class A. I don't know whether this is part of that technology. By coincidence I ordered a Marantz Quarter A amp on ebay today -- it's on a "30 day return" I would be very happy to take this one if I could hear it in my system before committing -- parcelmonkey please PM me if that arrangement suits you -- I'm in London.
