Tube preamp with Adcom amp

Thanks for all the recommendations. As for remote, that would be a plus but don't really need one.

I think adding a tube pre is a great idea, but it really depends on what sound characteristics you’re looking for as they run the gamut from neutral to warm and everything in between.  Any further thoughts/goals would be most helpful.

I have just bought a 1 year old UK designed icon Audio LA4 Mk 111 pre for just over US$1000, mainly out of curiosity given AbSounds very positive review. I changed the EH 6SN7 tubes with Shuguang Black Treasures and am amazed at the performance. It is the quietest tube pre I have ever heard and it outperformed my 5 times more expensive well reviewed pre in all ways  - black background, musicality, soundstage etc. I won't name the pre as I will be wanting to sell it but the icon is a bargain even buying new.

Find a good condition Counterpoint SA-5.1 preamp.  One of the best overall sounding preamps and they can be upgraded to reference level. Plus is has an OK built in phono stage if you care to venture into TT territory.

If you are on a budget and decent quality the Schiit Freya + with tubes $1199

and decent relay controlled volume ,not cheap Alps volume pot that looks 

like a round silver can just metal sprayed on plastic wipers.
