Tube or Solid State

How big is the room and what kinds of music do you care most about? Also what pre-amp will you be using?

I believe the MC2102 is 100 wpc and the MC402 is 400 wpc. The Ushers are around 89dB @ 8 ohm.

So 1 watt = 89dB, 2 = 92dB, 4 = 95dB, 8 = 98 dB, 16 = 101 dB and so forth. Once we get north of 100dB, I have to ask how loud is loud enough?

An increase from 200 to 400 wpc seems like a lot until you realize that the increase from 200 to 400 gives you the same thing as an increase from 2 watts to 4; that is, a 3dB increase in SPL. So the difference between 100 wpc and 400 is 6dB.

Assuming the impedence curve of the Ushers is fairley flat, that is, that they are not difficult to drive, the 2102 should be capable.

I have read that one tube watt is equal to two SS watts. I do not know if there is a scientific basis for this or not.

Hope this is helpful.

Cheers,

Jim,
I've read what you said regarding db's many times before but it never made much sense until now. Thank you!

Go with the solid state Mac. The often subtle differences between tubes and SS is the liquidity of the tube sound which I think can be largely lost when you are listening to really loud music, as you seem inclined to do. Now if you maintain a SPL level around 80db and have heard and appreciate the difference between tubes and ss go for the sound you like best. Either of these amps should be able to drive your speakers with comfortable head room for peaks.

I agree with Tvad, watts is watts, BUT I do think that the sound of tubes often has a fullness in the lower frequencies (the 'power frequencies') that may cause one to think they are hearing something more powerful. Not fact, just opinion though.
