unsound....
Aargh! I'm an idiot. The Primare I just purchased is the 34.2, not the model I stated in my previous post. Either Auto-fill got to me before I noticed or I just flubbed typing it.
In either case, Primare doesn't offer/disclose a 4 ohm rating in a few of their products. Bobby, my main consultant at Audio Den here, and I were equally surprised that they don't.
We're assuming a doubling of the 8 ohm rating, but we'd have to have someone test that.
From this site:
"The A34.2 is a 2 x 150 watt stereo power amplifier utilising proprietary UFPD technology. UFPD’s instantaneous rise time results in a naturally fast, clean and agile sound over a much wider frequency range and with exceptional headroom"
I just googled "UFPD Technology" and there is an interesting pdf from Primare that more or less/kind of explains the ideology.
At any rate, I'm liking it through my Audio Research LS 3 pre....
I will be looking at a BAT VK3i pre sometime this week...
