Is too much power in an amp really a problem?


As recently as 8-10 yrs. ago, I maintained my card carrying residence in the ‘lots o’ watts’ camp’ regularly. I’ve since held only a casual attendance to that group, and since departed with the acquisition of higher eff speakers, and lower powered tube amps.

Now I’m debating the future and appropriateness, of that perception and considering another SS, or a non tube amp. This time a digital amp… such as a class D or ICE configuration… as in a Bel Canto, PS Audio, Spectron, Wyred 4 S, etc., to use for both music and HT with my current Silverline speakers.

Several of these amps profess IMO rather high ratings for output power. 250, 300, and 500 wpc into 8 ohms, as your ‘oh by the way’ choices, and then doubling up should the impedance drop off to 4 ohms!

1000 wats per!

E frekin' Gad!

Truth be told, I’ve never put together a high eff speaker & high powered amp combo, nor felt the need, so I’m in a whole new ball game now, or am I?

I understand immense power reservoirs on tap, (like with my former BAT vk500) is a good thing, as well as are other attributes like a good input impedance, and control or damping figures. that amp ran VR4 JRs though, and both have since departed la casa Sunburn.

Additionally, my current tube mono blocks (120wpc) handle my 93db Sonata IIIs quite well IMO. My Odyssey Stratos SE also does a good enough job too rated at about 160 wpc. Between the two amps, the Dodds are the better sounding, and appear to have better control and more ease with the Silverliness.

In making a choice on one of these Digital or ICE amps, should the power numbers be regarded as something other than what they are? I mean more likely, do 250 wpc into 8 ohm rated ICE amps provide likewise results or the same feel, of an SS amp having the same output? Ie., control, power reserves, etc?

I do feel a good match between the speakers and amp is a prime consideration now, and do not wish to buy far too much or too little an amp, given these thoughts.

There too is the thought of the amps actual 'voice' itself to consider.

I sure wouldn’t want to smoke the speaks with too little or too much power on tap. Or have the amp ()s) always loafing. Or is that loafing bit just nonsense?

Any experiences and insights here on the digi power front is more than appreciated as I'm trying to get a 'feel' for this 'new to me' amp topology and not over or under buy.

Thanks much.

Hey I was going to answer this thread with some esoteric audio-crap opinion, but now I have forgotten what the thread was about.

So, what are we talking about again??

We paused for some further station identification and a few words on our sponsors.

I apologize for this interuption and now return to the show... (with any luck at all)

...ICE AMPS and their similarities & relationships with real world speakers, mainly in the moderate to high eff arena... 91-93db or greater.

Can a 'lots o watts ICE amp make beautiful music with reasonably high eff loudspeakers?

or should the two never meet?

Myself and several others that I know really like the Rowland Continuum 500 and/or 312 combined with speakers in this sensitivity range. The 91 to 93 range can actually be quite demanding if you enjoy peak sound pressure levels over 100 dB (think Mahler, etc.).

I think when you get sensitivity of 97dB and above, then I'm wondering if the power is of any use or could it even harm. I haven't tried that so I can't comment directly, but I'm very confident that there is a place for high power with 91-93dB sensitivity.

After you have thoroughly examined my posting history, please note that I use a Rowland Capri into a dbx Drive Rack and out to a Rowland 102 amplifier driving 108 db horns. I have a slight rushing sound from the dbx. When I bypass it and go straight from the 102 to the horns there is dead silence.

I have owned some kind of Rowland equipment or other since 1979 and have seen steady improvement in performance from every upgrade. During these years I have, of course, owned a lot of other gear concurrently. For reasons of convenience, preference and security, I keep returning to Jeff's stuff.

Despite the warnings that sometimes are issued against Class D, I have found it to be sonically exceptional and very user friendly. I'm quite happy with mine.
OK, I'm back on track now: amp power is completely speaker dependant. I have Maggies, and like lots of tordial power from Parasound, Bryston, and currently Cary (there are others). I have not really liked the digital amps I have tried, with the notable exception of the Innersound/Sanders Sound ESL amps. For some reason those sound much less dry to me.

I love tube amps for any speaker, of course depending on the speaker they need more or less power. But, power alone doesn't matter, it's more the load the speaker presents. That said, wow, more power is always better, never worse.
