For sale, we have a rare, vintage Audio Experience Music MK3. linestage tube preamp, from YS-Audio. This is an early Audio Experience preamp in very good physical condition, and it is in perfect working order. The Music MK3 uses 3 12AX7 Tubes, and a 5Y3GT as the rectifier tube. The 12AX7's that come with the preamp are Electro Harmonix, which all tested strong on our Amplitrex AT-1000 tube tester. The 5Y3GT rectifier tube is a Sovtek. We ran the preamp on our bench, and then in one of our house systems for about a week. We really enjoyed the unit, found it warm, and it had an impressive soundstage.
Physically, the unit is in excellent condition. The only blemish of note are a few light scratches on the rear left side of the unit. The last picture in the listing has a closeup of this. For further details on the physical condition, see the many pictures in our listing.
We don't have the original box for this unit, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.
