Mostly small scale boutique manufacturers for me. Point to point wiring and DHT pre's and amps, so more elemental circuits which means easier diy repairs if ever needed. Low heat with these components as well, heat the enemy of reliability.
Also, virtually none of the large scale manufacturers offer components that fit my needs or desires, SET and DHT are virtually exclusive domain of small scale manufacturers. The other thing I like about small scale is I can always directly communicate with the owner/designer of equipment.
