Quad 99 versus 909 amplifiers

[admin_exported]

Which sounds better, in terms of quality used at moderate power (e.g. 70wpc): a pair of 99 monoblocks, 99 stereo or 909 stereo. I know this is subjective, but pointers where to start will be appreciated. I will be driving electrostatic speakers (ESL 2905, very occasionally ESL 57). I measure quality as a combination of musical resolution, low distortion, clean higher music tones' frequencies and imaging - volume and power are not what drives my appreciation.

Maybe you could email Quad seeing as you're intending to use an all Quad system.

The 909 or the 909 monoblocks. It's not all about power, as you mention (resolution/low distortion etc). Better power amps will perform better, regardless of the volume.

It is a fairly common statement by many dealers that the 909 is "better" than the 99 (mono or stereo). However, Quad recommended a pair of 99 monoblocs, but did not offer an explanation even when I pressed them on the 'phone. And if the 909 is the "better" amp, do you know why then Quad have dropped the 909 from the Elite series? It's all quite confusing. Final question too please 🙂 Is there any difference between an early and a late 909?

What sort of sound are you after?

And I'm not saying mono 909's because I'm a dealer

I just had a look at your website and then at the Hi Fi X. Can I call
you tomorrow at work to discuss ths and a couple of other points that
came up as a result of that look? On 02476 525 200?
