Bottom Line:   
I was flabbergasted to read how good this is supposed to be, allready owning the old quad II and an audioresearch amp with a transcendent pre amp, I wanted something new and decided on the re issue Quad designed by Tim de Paravinci . At first I tought it was a mismatch with my speakers, but the other amps play so nice that finally I brought this amp to a friend who has other speakers and we listened and on his 3 systems it all sounded as dead as dead can be. He has Fostex basshorns with ribbon tweeter, a ceramic 3 way system and a big JBL monitor. So off the amp went to an audiogouroe, there it became apparent how low quality this thing is build. I'm still considering to let it be modded or to just sell it.

Bottom Line:   
The closest approach to the original sound was the line that Quad used to promote its’ hi-fi equipment in the past. Perhaps they should change the wording to ‘The original approach to the closest sound’ because they have created these amplifiers, based on the circuit topology of the past, but using modern components and high quality wiring.

The quad 11 forty are the power amplifiers and they are driven by a matching pre-amplifier called the QC twentyfour. The products are meant to be used together and in some markets are sold as a set.

I am a fan and I really enjoy using these amplifiers. I concede there may be amplifiers out there (tube or transistor) that may do certain things better than these amplifiers and that some audiophiles may huff and puff about old fashioned technology, or go on about harmonic distortion and all that, or power output, or frequency response. All I can say is that I’ve used a great many different modern amplifiers that all claimed better distortion specifications and more power than these amps and they all sound constrained and shut in by comparison to these units.

If you expect a mellow warm sound and an ovaltine glow from these amps you are in for a big surprise. Stan Curtis from Quad and Andy Grove (Audionote products of classic status) designed these amps to play rock and pop as well as jazz and classical music. The noise floor is very low, no hum from the speakers and less fizz than solid state amps at a similar gain setting, so silences are stark and quiet. There is a lack of intermodulation distortion that is quite eerie and this means that it is possible to follow each and every instrument in a good large scale classical recording. This is fantastic news for music lovers because you can listen to favourite recordings again and again and concentrate on a different instrument each time. There is always something new to hear and you never tire or fatigue from listening to the same recording. How many of you have records in your collection that you seldom listen to because they became boring with repetition? Not with these amps. You’ll want to dig out all your older recordings and listen to them afresh to hear all the subtleties that you missed first time around.

The power amps produce 40 watts a side. I guess that works out at about 100 watts of solid state power. Why watts from tube and tranny are different, I don’t know, but these amps go as loud, with considerable less strain, than my TagMcLaren 125 watt monoblocks.

The clarity, stage depth, presence and stereo width are impressive, but it is the neutrality and the projection of voices and instruments out into the room that is unsurpassed. The dynamic range is stunning and the way orchestral passages build up with layer upon layer of beautifully defined instruments rising above the others. The amplifiers seem to have limitless reserves of power available and this gives music at home the sense of realism that normally resides in concert halls. It’s very involving and once you’ve got a taste for it you don’t ever want to return to more mundane amplifiers. The vast power reserves mean that the amplifiers enjoy complex music and never appear to get bogged down, no matter what is being played. Music has the texture and lushness you expect from such amplifiers, but only if it is in the source material, and then there is that sense of great solidity to instruments with natural air and space that seems to be the preserve of valve amplifiers. Otherwise, the enthusiasm of the amplifiers allied to a great ability to track rhythm and pulse of the music means that just about every genre of music sounds – musical!
What about kick, slam, attack and agility? Here there is a difference with solid state presentation. The mid bass is not leaned out as in most solid state amplifiers and this means that bass guitar and cello, for example, are fuller, more natural sounding. The kick of drums is, as a result, more integrated into the sound stage during many rock and pop recordings. Listen to drums on their own however and there is great slam, attack and precision. During loud orchestral passages the amplifier easily shakes the walls and floor with the impact of a great bass drum being thumped hard and cymbals shimmering, stinging the ears, just as in a real concert. Voices - from great choirs to close mike’d vocals are totally convincing and solo instruments scythe out of the mix in impressive fashion.

This is a fabulous amplifier giving a lush full bodied and modern dynamic sound. Like all good amplifiers it needs good sources, interconnects and speakers. Take a mix of recordings along to any audition because good recordings will sound good and bad recordings will sound really bad. Your recordings may not be as good as you think they are and good amplifiers, being truthful, will not flatter bad records.

This is a good amplifier because it can really carry a tune and move the listener in a way that few others manage.
