what's going on with specs?


I'm having a hard time buying a power amp. I'm in the 5-10k range and whae I'm finding are things like PS Audio BHK 250. Specs show 250@8ohms and 500@4ohms. Then the Parasound JC5 shows 400@8ohms and 600@4ohms. Looks like PS Audio doubles at 4 ohms which makes me think it's a stronger amp until I notice the PS Audio spec is at 1 kilohertz and the Parasound measures 20 to 20 kilohertz. That is very confusing and I don't understand why PS Audio doesn't give full power measurements. Anyone with knowledge of these two brands or others. I have the Elac Vela 409s to drive.

If you’re discussing Watts, the room size, its acoustic liveness, and most importantly YOU and your musical choices and volume demands all matter in determining how much amp you want. SS amps generally have low output impedance and ones on your list have high current, so the 3.4 Ohm minimum of your speakers will not faze any of them nor cause major tonal surprises.
Even a Naim 80 W amp can deliver incredibly dynamic music reproduction. People love the Pass Labs 25 W amp. If you’re looking for nightclub volume you need all you can get…and bigger speakers.
