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.

A curious thread to the extent that only Larryi has addressed any of the downsides of higher powered amps. An amp with more output devices and higher wattage requires feedback to stabilize the circuit, a bad thing that, for lack of a better description, takes the life and vividness away from the sound. Amps with more output devices, and thus more complex circuits, are also noisier, something that can be audible in high resolution systems. It is often said that the best sounding amp in a particular line of amps is the lowest powered one.

Of course, a high-powered amp can sound better on inefficient speakers because such speakers require current to come alive, but precisely because such speakers have to be paired with high-powered amps featuring feedback, many consider inefficiency in speakers to be a design defect.

Very low-powered amps of course have their drawbacks, too. I run a darTZeel or a 65 watt/channel VAC 70/70 triode tube amp with zero feedback.

On another note, it pains me to endorse anything Audiofeil has written on this thread, but Mr. Corona's writings about Rowland on this forum, and his review of the revised Vienna Acoustics Mahler for TAS, are indeed curious (I have run Rowland gear without interruption since 1993 and owned the original version of Mahlers for six years - I have nothing against this gear and at least with respect to Rowland, stand to benefit from his positive comments if I sell).
If there is no benefit to higher power in any particular user's case, based on preferred listening SPL, room size, speaker efficiency, etc., then no reason to go there.

It will add cost to do a higher power amp well as Raquel relates so the benefits need matter.
"Mr. Corona's writings about Rowland on this forum, and his review of the revised Vienna Acoustics Mahler for TAS, are indeed curious"

Raquel - Beauty is in the eye of beerholder. If Mr. Corona likes Rowland's gear let him write about it. I hope you don't suspect some conspiracy here.

Myself, I bought Rowland class D amp based partially on reputation of the company that did not release any other than great products for almost 30 years. I'm writing as well a lot of positives on this forum about Rowland and amp that I enjoy a lot.
As much rhetoric is being cast about here with regard to Rowland, it's merits and perhaps some suspicious intents, which I've dismissed completely from my mind, would anyone care to compare any of these Lillyputian Giant killers to other more well known topologies and/or brands of amps by way of sonic diffs?

I should think that would glean certainly myself, and any other's on the digi ICE fence more palpable insights on what to expect.

Like for example: my xxx was as dynamic as my Krell, but sweet as my Carrisa on the top end.

or ... My xxx was as warm and musical as my SET mono's in the mids but far greater slam in the lower regions... etc.

guido, among others here has already seen in this instance anyways, I'll not be diving into a pair of Spectron Musician s, rowland 312s, or BC 500 - 1000 monos, anytime soon.

had I that sort of duckets to spend I'd be looking at Pass' XA 60.5 or 100.5 amps probably first... then the Spectron's & Rowlands thereafter. Maybe.

Thanks eternally.
Better yet...

How many high powered ICE users here have high eff speakers with dubious impedance loads? Like the sonata IIIs ... 93db & approx. 4 ohms -/+ ?
