Recommend me a tube integrated amplifier

Tube amps have a huge variation in presentation.  I would recommend listening to as many as you can before jump into it. I've listened to several types and it's more than just Class A , Push Pull, SET and how much power they provide.  Each tube has its own sonic qualities. 

The only recommendation I could make is to try to listen to a 845 tube based amplifier prior to purchasing.  It might cause you to reevaluate your budget as it did me but then again you might prefer a completely sound pallet than mine.

Here’s a very highly regarded Audio Hungary amp well worth a look.  Best of luck.

I was curious about tubes as well, so I have a second system with a 100db speaker to try out flea watt SET amps (300b, 45, 2a3) known for their midrange tube magic.  

As long as the sub has a high level input, almost all amps will drive them from the speaker outputs. The sub HL inputs have very high impedence and do not load the amp. 

Anyone verify they can be connected speaker level to both speakers and a sub?

My amps of choice.
