Need Some Tube Amp Advice

Check out Quicksilver Audio, they are sure to have something to meet your needs on both the amp and preamp, Carved also has a pair of mono block, 75 watt amps that look to be a steel at around $2,700.00. I personally replaced a pair of VTL 125 monos that were 20 years old with a pair of the QS m120s at 1/2 the price and love them. Enjoy the music.

You might be better off with getting an integrated amp. Check out  this Rogue Audio integrated, it includes a phono section. It should fit the bill!

Line Magnetic makes a nice line of integrated tube amps.

Luxman makes SQ-N150 integrated (10 wpc) includes phono preamp and remote. I great sounding amp at $2,795  with plenty of power for your speakers

What's your budget? The Cornwalls are pretty tube-friendly.

You don't need a lot of power so this is all about nuance. Smaller tube amps often have more bandwidth (although because our amps are output transformerless this doesn't apply to our amps) which allows them to be more spacious.
If you decide to go with an SET (Single Ended Triode) amplifier, keep in mind that whatever power the amp is rated, you will not want to exceed about 20% of that power in order to get the most out of that amp. With push-pull amps this isn't true- they typically have a much wider 'usable power' range (SETs are typically 10% distortion at full power; to keep that down and hear what they are really about you need to stick to that 20% rule). A push-pull amp that will do the job on a speaker with this sort of efficiency need only make about 15-30 watts. A lot depends on room size and how lively it is! Because of the lower power requirements, a triode amplifier is nice (and there are triode amps that are push-pull).
If you get this right you'll be hearing things in the music you didn't know were there and overall the system will also play in a more relaxed effortless manner. One thing to keep in mind- its not so much about money as it is about nuance. There are good inexpensive amps and there are good expensive amps, along with their opposites.

Are you planning monoblocks or a stereo amp? Balanced or single-ended connections? How big is your room and how lively is it? These are things that will help people here be able to help you more.

I live in a loft space with 15 foot ceilings in downtown Miami! Basically a cement rectangle with polished cement floors! Its 900+ sf and I have an 8'X 10 foot oriental carpet running down the length of the apartment as well as a 4X6 foot in front of the system! So to say the room is lively its an understatement! But at one end of the rectangle is my bed which offers no return off the wall.
