Being a soundstage junkie, I've been keen to try out a CJ as they seem to have a reputation in this area. Well, I've got this mid-1990's Premier 11A power amp (and a PV12 pre-amp) on loan from a mate and the reputation is clearly well deserved. On the right material (eg, Tracy Chapman s/t on vinyl) my Audio Physic Tempo 25 speakers just disappear. Lovely bit of kit, really sweet and balanced sounding, and not exactly ugly to look at either . It's 70wpc & uses 2 x 5751, 2 x 6FQ7 and 4 x 6550 for output. Input tubes are all GE JAN, 6550s are Sylvania. Sadly the PV12 pre-amp is faulty so I'm using a Jotunheim instead, which actually does the CJ no favours at all, closing things in a bit. Connecting my DAC/passive preamp (DiDiT DAC212SE) straight to the CJ restores the soundstage, so Jot is doing something funky in this setup. I've also got a really nice upgraded First Watt F7 build here for a couple of weeks to compare. I'll update this thread if anyone is interested in impressions.
