Stereophile Class A

For a $1000 best to get a used integrated amp. You may be able to find a YBA Integre for about $1K. Maybe a Creek 5350. The 5350SE might be more since it is a new model, but the 5350R will be around $1K. Also look for a Classe CAP-100.

Do not forsake the Class B list. There is some very nice stuff there and some for a lot less than $1K. Bryston B60; Musical Fidelity A220 or A2; Linn Majik and many others.

Saw on rec.audio.marketplace a pair of Meitner MTR-101 monoblocs (100 wrms into 8 ohms, 200 wrms into 4); seller asking US$700 (retail 1990, $3400). They're A/B, not class A, but my advice is: BUY THEM! I would, except that I already have a pair, plus their smaller 50 wpc STR-55 in my bedroom system. These are extremely powerful, very accurate (but rich), detailed mono amps. They'll drive most anything; they have beautiful polished hardwood sleeves. MOSFET output devices. No longer in production, but still serviced and upgraded by A/D/S in Calgary, AB, Canada.
To do significantly better, you'd have to spend thousands.
Good luck.

The Musical Fidelity A3cr is currently a Stereophile "Class A" though it is I believe a Class A/B operation amp. It sells for ca. $1500 new and I have seen it used for $850-$1200 depending on conditionand age. I have one (with the matching pre-amp and love it.

Before I make any suggestions, I need to know what speakers you are going to be driving.

You need an amp that are going to match you speakers.

Peace.

The Rogue 88 (tubes) is excellent for the money. Can be purchased for under $1000. Can be updated later to Magnum series. Look at an Anthem Pre1L for about $400. Tubes and a great deal at the used price. If you want to keep the cost down look at Cambridge Audio solid state gear. They are an excellent value for the money.
