Not a bad call but I cannot comment on price…tho if not already done would benefit from replacing the cheap pots, switches and with a handfull better quality caps and resisters under the hood, a friend did just so and took the SQ of his up a level.
An AI500 working properly is a 25W/ch amp. If you had a 100W/ch amp it would only be 6dB louder. The noise floor can be very valve-dependent. In a perfect world you’d break into Langrex late at night and work your way through their stock of ECC83s until you found enough quiet ones.
Saw the monos and thought that they come in on budget and posted, then my glacial memory said “oh, he wanted an integrated with phono stage” and added the text.
It does say “220V model” at the bottom of the listing. It might be OK across the full EU voltage range, but I can’t see a CE mark on the rear, which is slightly odd.
