SOLD: Mapletree MAD EAR+ HD Special Edition headphone amp w/NOS tube assortment
Will Ship To: Anywhere
For sale: Dr. Lloyd Peppard's Special Edition Mapletree MAD EAR+HD headphone amplifier/preamp (serial #250). This is a one-of-a-kind "tweaked out best version" of the popular EAR+ HD amp finished in a unique color scheme featuring gold plated tube socket, NOS Noble stepped attenuator, and is one of the last units to feature the Black Gate filter capacitor upgrade. Side panels are selected maple with heart and sapwood patterns. It can also be used as a preamp (has two inputs and one output).
The Grado + Mapletree synergy is well-known by now, but this amp can drive headphones of low and high impedance (including the HD800) superbly at its price point. It has two dedicated headphone jacks: One for low-impedance, one for high-impedance. I am the second owner of this versatile amp (purchased originally from rattesp on Head-Fi via http://www.head-fi.org/t/552710/mad-ear-hd-special-edition-s-n-250).
The tube complement has been narrowed down from a handful of "OK" ones to only the best ones I found for it: A pair of GE JAN 12B4A's, a 1950's military-issue JHS Sylvania 5751 (triple mica, black plates, gold label... nice tube), and one JAN Sylvania 12AX7 green label w/dual grey plates. I recommend using the JHS 5751 blackplate with Grados, and the JAN 12AX7 with Senns.
Ouch... you guys are killing me on the price! Originally this bundle is worth about $1000. Now SOLD... thanks for your interest!
