Hi ACD,
Compared to what other preamp? It's not bad at all if that's what you are asking.

Compare to all other preamps

The reason I ask is that I have never had a chance listen to it.....

Hi ACD,
How can I answer that?

They can be better than many and not as good as some. It is a worthwhile preamp. Sometimes cost has no relation to performance, so this one may turn out better than you expect.

Hi Chris

Some older pre- and power amps has either good or bad reputation

Did a search here, however got no matches at all........

Maybe it's rock solid and never needs repair or it's to good to be modifyed... or it's a piece of junk, that no member of this forum had never bought

Hi ACD,
Well, I'm not going to say they are the best. But I have had reasonable luck with Denon designs. They tend to build good, clean circuits without too much silly stuff. Yamaha would be another good one, but they tend to build some circuits in an over complicated way.

Does that help?

-Chris

I have a PRA-1200 with analog switches, worked very good for 15 years and is still good. I have used it every day since I have TV sound through it. A friend of mine has I think PRA-1000, some model older than mine and it has mechanical switches which are not so good I'm afraid, bad contact nowadays.

The design inside in PRA-1200 is very well done for being a Japan amp. Low noise JFET's, DC-servos etc.

...so if the input selector and the pots are OK it's definitely a good amp if you'll get it cheap.

Hi Peranders

I once also had a PRA-1200 - nice sounding pre

I could be interesting if somebody has the schematic for the PRA-1000

Hi AC,

Then you should know they always decide to make one circuit overly complicated. Otherwise good product.

Ahhh Ha! So you've never looked under the hood! They did sound okay.

That's what I was trying to get across. I wouldn't mind a schematic either. I have a pair of Marantz 3650's. The switches are bad on both! Otherwise excellent product.
