I owned one and found it lifeless. Yes, ahead of its time in the 1980s, but much has changed since then. And perhaps, mine was out of spec. I would look elsewhere such as Audio Refinement or any other very decent preamps.
Is an Apt preamp a good preamp for my setup.
My system is a marantz cd-67se connected direct to a BEL 1001 amp with the sound fed into a pair of wharfedale diamond II's. Have a chance to purchase a Apt preamp and wondered if it would be a good fit to my system. Plus does anyone currently run the Apt, how do you like it and do you have a copy of the owners manual. The one forsale does not have the manual but it does have the schematic sheet attached to the bottom.
