For Sale: FS: EarMax Anniversary Headphone Amplifier - SOLD

The EarMax Anniversary is just one in a line-up of vacuum tube headphone amplifiers bearing the EarMax name. There are four EarMax amps in the line-up, which consists of the standard EarMax, the Pro, the Silver, and of course, the Anniversary. All four versions share the same basic physical design - an approximate 3.5" square base, on which 3 tubes are installed, and then partially protected with a wireframe "cage" over all three tubes. At 3.5" square, the EarMax amps are certainly one of the smallest headphone amps in the world regardless of the fact that they run with a complement of vacuum tubes.

Common to all four EarMax versions is an OTL Class A Triode design, an approach which lends itself well towards driving efficient headphones. Indeed, the four EarMax amps are probably best used with efficient low-impedance headphones like those from Grado and Audio-Technica, but it's primarily the Pro that's been designed with low-impedance headphones in mind with its 35 mW per channel output - the Silver and Anniversary have 50 mW per channel output and I have found the Anniversary is an ideal amplifier for the Sennheiser HD650.

Unique to the EarMax Anniversary specifically, is a larger power supply unit over the standard and Pro, upgraded internal components, gold-plated parts including the RCA jacks, a 4-conductor power supply cable and ceramic tube sockets. It is called the Anniversary as it celebrated the 10th year of the EarMax product line upon its release in 2005, and as part of that celebration it received a gold color theme, a deluxe metal "bombproof" style carrying case, along with a very, very limited release - only 100 pieces made for the world-wide market, just 33 of those for North America! A collector's item for sure.

This particular example is serial number 27, a very low and desirable number indeed. The tube complement is one NOS Amperex Bugle Boy ECC81/12AT7, TK1, Date Code 9-47, made in Great Britain; one NOS Amperex PQ (Premium Quality) 7308, Gold Pin, VR5 *6E, Date Code: 66-33, made in USA; and one NOS Amperex PQ (Premium Quality) 7308/E188CC, Gold Pin, 43C1 - 11M, made in Holland. This unit has been very gently used for approximately 50 Hrs only and has always been stored in it’s metal protective case.
