TOTL Headphone Amps

I don't know if I'd call the HA 430 "TOTL", but I have one and it's fantastic.  The Sony TA-ZH1ES is also excellent.  I have no experience with the Rogue amp.  Others I've owned or own:

Hifiman EF6 (it's a beast!)
Auralic Taurus
Musical Fidelity M1 HPAP
Oppo HA-1

Guys, I hope I don't come off as a snob and don't mean to belittle your gear. There are a lot of nice headphone amps available for under $1K and I'm sure some "punch above their weight", but I don't think the amps you're discussing are in the same league as those being discussed by the OP.

The 430HA is a great amp, very neutral with tons of power. Some characterize it as slow and boring. If your preference is for something more on the hyped up side, it might not be the best choice. I find it very easy to listen to, with great detail. The volume control is excellent, providing almost infinite control over volume settings. 

@oddiofyl  I'm glad to hear that.  I have some nice stuff, but it's mostly "mid-fi" and most of it I have purchased second hand.

First off, I'm not really a DIY person, I like to purchase fully realized products.  You may have me confused with someone else.

I have no doubt that I would enjoy listening to those amps.  Headphones amps (and a lot of the other gear we use to enjoy our hobby) don't have to cost a lot to be good. 

I recently sold my Musical Fidelity M1 HPAP headphone amp, which originally sold for $799.  It was class A and had a lot of power, two inputs, and sounded really good.  I'm sure the person I sold it to is enjoying it as much as I did.  If I would have had to sell all my other amps for some reason and only keep that one, it would have been only a minor "downgrade", more a loss of features than anything else.  I think it sounded as good or better than the Oppo HA-1 headphone amp I had.

I've moved on to some more expensive gear and it does sound better, but incrementally.  In most cases, there were features those pieces had that were also important in my purchasing decision when I decided to upgrade.

I don't think something like the Manley headphone amp is "worth it" for any practical reason.  I think much of what you're paying for is the look of it, which of course is hard to put a value on.  It's unique and would be something to show off if you're into that sort of thing.  I have a Manley Chinook phono stage and think it's a really nice piece, but there's nothing flashy about it and it was "affordable" for me.

@cbl117 Sorry, I missed your question.  I haven't used them both in the same system, so the sources were different.  I had the Taurus in my main system, which of course has my best components.

I found the 430HA to have more power and to be a little more detailed than the Taurus.  I think they were more alike than different in terms of the sound signature (both fairly neutral), but the 430HA has a lot more power and gives you more flexibility in terms of outputs with the rest of your system as well as remote control.  

Glad to hear you're liking the 430HA. It's my favorite. 

For others still considering a great headphone amp, the other one I have that rises to the top of the many I've tried is the Sony TAZH1ES.  It has a really good DAC, a ton of power, great dynamics and is very clean sounding.
