Which headphone amplifier with balanced input?

IMO, the Sugden Headmaster is an excellent solid state headamp (very quick, precise, and detailed) with an absolutely beautiful finish and outstanding build quality, but it's a bit on the expensive side if you buy it new. It mates particularly well with the Grado HP-1000 series headphones as well as the AKG K-1000 earspeakers. Check with Carlo (his username) at head-fi.org concerning the mods that he does for the Headmaster that are reputed to be an outstanding value and bring the amp up several notches in the foodchain. My Headmaster is unmodified but I'm definitely considering the possibliity of having Carlo do his magic.

As I mentioned in my previous post, the Ray Samuels XP-7 would be an excellent buy (the company name is Emmeline Audio). Also, the SinglePower Audio products from Mikhail (another head-fi username) are "bang for the buck" headamp champs. I don't mean to be repeating myself, but these DIY bargains should not be overlooked. One last option would be the Perreaux SXH1 for $349 from Audio Advisor. This is another headamp that has received a lot of attantion and great reviews of late at head-fi.

Good luck.

Hey, it's nice to see all of the referrals to head-fi, which is definitely the best place to ask this sort of question but it's always nice to hear from the Audiogon crowd on headphone-related matters as well.

Depending on your budget, I wholeheartedly agree with the XP-7 recommendation. It's hard to believe that this is a $495 headamp because the soundstaging it produces in awe inspiring - and it's a small portable headamp! I just got mine this past weekend so I'm still in the honeymoon stages with it, but it's leagues ahead of my Creek OBH-11SE or Antique Sound Labs MG Head. My first impressions are that the XP-7 may just compare favorably with well respected headamps in a slightly higher price category such as the David Berning micro ZOTL or the Sugden Headmaster, but I have not done any A/B comparisons yet. Ray Samuels is a great person to work with as well (as is David Berning).

As another suggestion, a head-fi member named Mikhail also produces some excellent tube amps in all price ranges that are a great bang for the buck. The company name is Single Power Audio, and I'm sure he could include balanced inputs in the design if you so require.
