Can you ever have too much power?

Too much power (especially with a very sensative amp) can get you into trouble if you have very sensative speakers and a stepped preamp.

Basically, in this situation, you could hit a very loud volume at 1 or two notches on your preamp. This gives you lousy volume control.

THe problems above actually (upon a little reflection) are primarily caused by the sensativity of the amp and not power per se.... But too much power in this case can blow real sensative speakers easily.

I think amp designers will agree that is much easier to build a 25wpc amp that sounds wonderful within it's power range than it is to build a 500wpc channel amp that sounds wonderful in it's power range. It is also a lot cheaper. My theory is that unless your speaker really require amazing power, there is little need to go overboard on power.

Then there are speakers that love power.... Maggie 3.6's.... If I could have fed the Pass X-1000's to my Maggies, I would have. 2000wpc and ungodly amps of current into the Maggies would have made em sing.

Didn't you hear his speech last night?

LMAO Subaruguru!

I used to go for MONDO power when running SS amps (class A/B). Now that I've switched to tubes, I like to use reasonable powered amps (say 50%-75% of rated speaker handling power). I'm using an Atma-sphere M-60 MkII.2 (60 watt mono's). Replacement power tubes 6AS7's are relatively cheap ($15-16 ea.) but even so, at this price, a set of 16 (8 per monoblock) will still cost $240-. At least Ralph doesn't run the tubes at maximum parameters, so a set should be good for 2-3 years. Other manufacturers run their circuits with the tubes maxed out (and some can be much more expensive than the 6AS7's) and are know for chewing up tubes (under a year). The MA-2 Mk. II.3 mono's at 220 watts requires a total of 40 tubes...you do the arithmatic! Not to mention the the way, WAY higher list price for an increase of slightly less than a 6 dB's of power gain over the M-60's! Why pay "mucho dinero" for something that you don't need (braggin' rights?) Especially since "tube watts" don't clip out like transistor watts will. Then there's the heat factor. Since I'm in an apartment, the air conditioning fan unit is in the hallway, and I must shut it off for any serious listening. Windows are closed (so as not to piss off the neighbors...and the management). This can be a challange on 110 degree day of an Arizona summer! At least I can keep the amp in standby (filaments on, plate voltage off) when not listening. It's a class "A" amps, so the filaments aren't the heat generators or power hogs). If you're running a class "A" transistor amp, you should leave it on all the time. Not only do they generate a ton of heat, but the idle current (power on, with no signal) can EASILY add $20 to $100 to your monthly power bill. But who ever said "braggin' rights" come cheaply!

Yes, I used to think that I needed a 3.5 watt 2A3 amp, but I found out that my system did all I wanted with a 2 watt 45 amp instead.
