I’ve so far tried a Leak Stereo 20, Leak TL12+ monos, a Quad 303 and a Pass Aleph 3 with either a Audio Synthesis ProPassion or a Verdier Control B preamp. They all work well and bring slightly different things. I’d really struggle to rank them.
Naim NAP 140 is a very good match, strange as it may seem. I use mine with a DIY passive pre with a pair of Khozmo stepped attenuators and it's about as good as it needs to be. Not nearly as good with a Naim preamp, though.
My Gold badge Q7s are new as of yesterday and being fed by a Rega Aethos. Makes it difficult to make a amplifier comparison....... unhelpfully I can make a speaker comparison already, far more detailed than PMC 21s!
Sunny Suffolk!Oh to compare my 'regular' with your silver badge ! Whereabouts are you ?
