For the price point I would checkout Spearit Audio online based in MA. They are dealers in Conrad Johnson which are outstanding tube and SS products. The SPEARING owners is retiring and they have a lot of new and used gear for sale at good prices. A Classic tube preamp should be accessible. Great sound. Only issue for me is no remote.
Aric Audio Systems Unlimited Preamp
They have a tube model called Unlimited that appears to be a decent value for < $800. It is tube rectified and with pair of tube voltage regulators and 12AX7 driver tubes. It even has a phono stage. Anyone is familiar with this preamp?
