TOTL Headphone Amps

Three noteworthy amps, from my experience:

Benchmark HPA4 - maximum transparency and detail, clinical in its precision 

Ampsandsound Bigger Ben - incredible musicality, a touch of warmth, lots of power

JDS Labs EL II - All-around solid performer at a budget price of $250

The Darkvoice 336SE OTL amp would be an interesting choice, haven't heard it but I imagine it'll have a distinct sound: alas, I've heard about quality control issues.

WA33 is probably the best tube-based option. If your preferences run Solid State I'd consider the HeadAmp GS-X mk2, and if aesthetics don't matter to you, the Audio-GD Master 9.

The best deal out there on an excellent OTL (David Berring’s ZOTL design) is the $1250 Linear Tube Audio ZOTL. I actually have David’s prototype of this amp that is so good that it can also be used as a preamp in a very high end system! Also as an amp for very high efficiency speakers. Natural, smooth clear.

@mglik , yes but I believe it’s only 1 watt to speakers.

However regarding your post, I’m sure it’s an outstanding headphone amplifier. LTA has been on my shortlist for a while.

In my dream setup, I would have an OTL amp driving some 300 ohm cans for classical and jazz and everything acoustic. That is my search. Just discovered about the Glen headphone amplifier. I’m reading different things but apparently it’s a 6 to 12 month wait time.

I also listen to a lot of electronic drum and bass and jungle. For that, my Hegel Rost driving my Arya is much better then my Burson and MHDT DAC. Frankly, it sounds so good on classical and jazz I have to be out of my mind to consider anything else.
