It's reasonable value for money. Let's leave it at that. ;-)

Okay, the crunch question is this: do you think the amp in question will
sound better or worse than a Cyrus 2? And why?

Maybe so, but how far downwards can the quality go, if they are to get
away with calling it a 'reference class studio monitor'?

'Reference' and 'studio' are often adspeak. Like 'pro'. A monitor is a
speaker, not an amp, in this context.

I dunno - you'd have to audition both. But my gut feeling is the Cyrus
would be better for domestic use.

There have been several threads in rec.audio.pro about Behringer
kit. Divides into those who like it and can't believe the price and
those who are prejudiced against it. The usual argument is that
they are charging premium prices for setting up their sound systems
for gigs and customers wouldn't approve of 'cheapo' kit! There
have been some notable conversions of the sceptical. Some say
that at first B kit was sometimes unreliable though it is generally
agreed that this is not longer true if it ever was. Apparently Uli
Behringer lurks on the audio ngs and takes note. To give you
a taste, have a look at the manual for the CX3400 XO on their site:
www.behringer.com. It's downloadable as an acrobat file. It's
an essay on setting up multiple speaker sound systems.

Early days but I'm impressed with the 3400 so far.

I can appreciate that, but they don't use those terms WRT to their other
amps, which are patently PA jobbies, the spec for the lower-powered one
being 260Wpc into 8 ohms, 0.1% THD, -100dB noise 20-20K, freq resp +/-1dB
20-20K, 3dB points at 5-50K. I think the message between the lines is that
the new one is better than the PA ones.


Like 'pro'. A monitor is a
speaker, not an amp, in this context.

My error - the official spielspeak is "Professional 500-Watt Reference-Class
Studio Power Amplifier".

Same here. I'm still at the stage of trawling through my CDs, hearing stuff
I didn't know was there. I honestly didn't expect to be doing that - I
thought I'd have a better sound at high volumes, but an overall loss in
fidelity. It may well be taking something away, but, if it is, then the
change in amp and passive xover configuration seems to offsetting that. So
far, the difference is a nett gain - I'm really glad you mentioned it in
that other thread!

I've found a forthcoming power amplifier that I may be interested
in, but the only specs available at present are that it does 500W
into 8 ohms bridged for mono, and 230W per channel into 4 ohms.

What would be its likely stereo output into 8 ohms?

Likely to be about 130 watts/channel into 8 ohms, but that alone
doesn't make it a good amplifier...


That presumes that the power amp's power supply and other components
result in a power amp that performs like an ideal constant-voltage
source.

An amp with poorer power supply regulation will produce less than
twice as much power at 4 ohms, than 8 ohms.

For example, some of the low-cost "plate" subwoofer power amps have
the same rated power output at both 4 and 8 ohms. Their power supply
regulation, etc. is obviously a lot less than ideal.

ones.

The hidden agenda is that most PA amps have specs equal or better than
HiFi amps, if you back off their power ratings. IOW, take a 200 wpc
power amp with speced 1% THD, drop the power rating back to 160 wpc,
and watch the THD drop to 0.05% or better.

Case in point are my bench measurements on a QSC USA 400. At 130 wpc
it might have like 0.5% THD. Upon closer examination, the amp is
barely clipping. Back off the power output to say 100 wpc, the
clipping goes away, and the THD drops down to about 0.01%.

The wording in the spec sheet is...

20 Hz - 20 kHz @ 0.1% THD, both channels driven:

8 ohms per channel: 260 W

4 ohms per channel: 400 W


Is there any reason to think that the quoted THD is at anything other than
the quoted output?

I must admit my views are based on their compressor/limiters. Which a
'fan' installed in a facility I sometimes work in. And I dislike them
intensely - I bring in my 30 year old Neves which work rather better. Of
course they cost many many times the price.
