hey, I am the new importer for Art Audio. The Jota is a lovely amp. We encourage you to look at very low gain with a tube stage for pairing with the any of our SETs. The volume control is just a volume POT in a passive stage.
The recommended preamp from Art Audio would be the Conductor Simply 2 which lists for $5500.
