Inexpensive integrated tube amp recommendations?

Audio Space AS-3i might go for around your figure used.

Point-to-point, three inputs, the output power you want plus the ability to switch to triode mode from the front panel.

cayin is the way to go, great sound, great value.

The Jolida JD-707A is a very musical 40wpc integrated, but it's around $1200 I think. If you can find one here on Audiogon, it would be worth considering. Other amps in the line that you might consider are the 102B (25wpc) for $650 or the 202A (60wpc) for $850.

Used Cayin A50T should be available or around or just over $800.

Not sure what inexpensive means, but it seem Cayin and Prima Luna are on the must audition list for high value tube integrateds. I'm not sure, but I suspect they are both a step up from Jolida.
