Audio Research LS27 (used) - Preamp is in excellent condition as you can see in the pictures. Electro Harmonix 6H30 tubes test perfect. Serial 62105702. Original box and manual. This is a good choice if you need XLR jacks. If you don’t need that you can do a lot better with a PrimaLuna DiaLogue Premium preamp for about the same price. That’s what this preamp was traded in towards, and the customer never looked back.

The ARC has two chips that cost $4.15 each for volume controls, printed circuit boards in the signal path, and 6H30 tubes which sound rather thin. Plus it only weighs 16.5lbs. The PrimaLuna is 53lbs thanks to its two massive power transformers. It's dual-mono... only the volume control is shared between both channels, tube rectified, and has point to point wiring with Swiss made silver plated OFC cable AND custom Takman resistors in the signal path. The volume control is analogue using a very expensive Alps Blue Velvet potentiometer. And it uses the wonderful 12AU7 tubes which is the #1 favorite for tube rollers.
