As an alternative integrated tube amplifier, consider one of the Audiomats. They start with Aloha, Arpege, Aria, Adagio, Opera, Solfège. Here’s a link to their webpage

The North American rep is located in Canada, Pasqual Ravach.
i have lived with two of their integrated amplifiers, the Arpege and the Prelude Reference MKII for almost 25 years and they are wonderful products, really solid, utterly reliable and musically outstanding. I think they are priced below their real value. Check out any of their reviews and you will find them very positive. They are sadly not well known in the US.
