Tube Integrated vs Tube Seperates

LM 508ia is way better in your price range.

as tube 805 is on very high level of the tube world and they provide 48w X2 power,which can meet a lot of speaker.

Separates is going to in most cases get you better power supplies optimized for the job at hand. I would MUCH rather have monoblock amplifiers located within 12”-24” of the speakers and an XLR balanced connection to the preamp. Depending on length of run and RF environment, you might be ok single ended RCA. You could get very close to this with Quicksilver amps and a pre at top end of your budget. What speakers are you running, how big is the room, how loud do you listen ?

I have had integrated dual mono amps that never sounded as good as my primaluna pre and amp.  I am getting another evo400 to run both in mono.  You will find separates to your liking.

PrimaLuna fine at your budget level. Separates better but you'd have to stretch budget. Actually, I'd rather have the PL integrated with it's active pre vs some of the other tube amps with passive pre's.

I prefer the simplicity and sound of a high quality integrated tube amplifiers like the Audio Hungary Qualiton Series. But they are above your budget even used.

My X200 smokes every PL, AR and Mac separate I have ever owned.
