This is a Mapletree Audio Magic 5B SE Triplex Tube Preamplifier. Wow, what a mouthful!
Anyway, what this is is a fun tool for experimenters and the continual tweak in all of us! Giving three modes of operation: Passive, SRPP, and Cathode Follower, with corresponding increases in gain, this preamplifier brings that warm tube glow to anything passed through it (with preamplification engaged, of course!). There's also gain and volume, so you can decide how hard to drive the circuit. Hours of fun in one box!
This preamp came from the estate of a local audiophile, and has been working my house for the last couple weeks with nary a hiccup. After a quick clean of the input selector with deoxit, there have been zero issues.
It looks cool, sounds great, and offers a multitude of options. What's not to love? I liked the SRPP setting the best in my test setup, which leans a little bright, but the gain of the Cathode Follower was additive, too.
