Integrated Tube Amp approx. $2,500

Have a look at the Muzishare X7. I've had one for almost a year now, well built and sounds excellent. I had looked at the Willsenton but they had way too many issues, the X7 has been rock solid quality wise.

I would not look at any of the offshore offerings that do not have local service support in your market. Save your money and look at brands that have distribution and service support.

I run the Quicksilver 20wpc integrated with a pair of vintage Klipsch Belles (104db @ 1 watt) and it's a very nice combination - I rarely have the volume knob past 10 o'clock.  Plus, Mike Sanders is a pleasure to deal with.  Both he and his company have been around for a while, so I would expect no dramas or future concerns.

I can second newfxz ‘s suggestion on the Muzishare X7. I owned one for a short time, and only sold it to move to a dedicated power amp. Great build quality and it’s  point to point wired which should offer better reliability and ease of repair by most competent shops if something does go wrong. I’m pretty sure these are built in the Line Magnetic factory.

The Wilsentons get a lot of great reviews, but I don’t have any direct experience with them. Well under your budget.

Rogers 65V-2 Integrated Tube Amplifier. If you call you get for less than the eBay listing price. Rogers High Fidelity integrated Amps are the real deal.
