SUGGEST A TUBE AMP?

Quicksilver makes some nice amps here in the US, they've been in business a very long time and have a great reputation.

My first foray into tubes was a pair of QS 8417 mono's that I mated with Quad 63's; wonderful sound! I sold them three years later for exactly what I paid for them.

An Atma-Sphere S-30 would match very neatly.

Atmasphere for "...UNDER A GRANDE{sic}..."?

Unsound, an S-30 was just recently offered here for $1100. Don't know what the actual selling price was. List new is $3200.

For under a grand I would suggest a Conrad-Johnson MV 52. Usually goes for around $800. Try to get the 52 over the 50. The 52 has all polypropalene caps in the power supply.

BTW, I'm a long term S30 owner. If you can get one for around a thousand dollars, go for it, though I'd be a little cautious about why it's priced that low. Typically. it goes for $1800-2500 used.
