hi all,

when manufacturers of studio amps like alesis, samson, and hafler post the power ratings of their amps, are they posting in RMS power or peak power? I know most consumer companies post in peak and most audiophile companies post in rms and peak - but none of the studio amp manufactures seem to want to post wheather the figure is a peak or rms figure. I'm assuming that an alesis ra100 is capable at riding along at 100wpc @ 4ohms all day. . . . am I wrong?
 
There is more too!!!

Not every manufacture uses the same testing parameters for testing their amps either.

I wish I has time to find the technical paper I read from a website that did a lot of benchmark and product testing so I could link you to it, but alas, I leave here in 30 minutes and don't have the time to find it.

Yeah, 100watts, probably RMS sounds about right. But, I would avoid the Alesis amp like the plague. Hafler is really the only way to go for powering studio monitors.

Phase Linear 400 the best sounding amp in the world.I use them in my studio, home stereo and PA for my band.360 watts per channel into 4 ohms.Sell for about 400 on eBay.
 
really?

I know that most low-cost alesis stuff blows, but I thought the ra100 was as clean and powerfull as one would need, certainly a bit better than the samsons. Why should one avoid the ra100, everyone seems to like it? Have you tried one personally? I know hafler is best, but you pay for it too.

just curious.

thanks,

patrick
 
RE-100....YUK!!!

A studio that I work at sometimes used to have a RA-100, before the owner bought a Hafler. The difference is very noticeable. The RA-100 just doesn't seem to handle the low end very well at all, and the sound seems sort of colored. I would avoid them. They just are not a very good monitor power amp.

There may be many good amps out there that will work. But, you look around at many very big studios equipment lists, and Hafler is going to show up over half the time. They just outright are a clean, dependable, well made amplifier. The TransNova series is revered in studios for the most part. I have never heard a single complaint about them at all from anyone (except possibly the price tag...:D )

then make mine hafler

ok, I'm sold. . . . I'll keep my eye out for a good used transnova in the 70wpc @ 8ohms and up range. For now my trusty NAD stereo amp (which seems slightly full/warm in coloration, but I know it well) will have to do.

thanks for the personal testimony.
 
OK just a little pop quiz for you guys. What was David Haflers First amplifiers called? and what was Bob Carvers first amplifiers called.
 
The Cube

Dunno about Hafler,but Carver's was called the Cube.Now,What'd I win?
 
No cigar Ray. I will wait for a few more answers then I'll spill the beans.
 
Hafler

David Hafler's first company was formed in the mid 50s . It was called Dynaco.There are more of these in existence than any other amp. Bob Carver's first company was formed in the early 70s It was called Phase Linear. There are many nice pics of these old amps on e Bay, check them out.
 
good one Paulie - I remember both those old companies - I still love the BRYSTON amps.
cheers
