Glad the Sylvania's worked for you, probably my favorite sounding preamp tube.

Thanks for the review. I’m thinking about buying an NFB 11.28 for solid state(critical listening) and then a Tor Roger tube amp for more buttery smooth sound and maybe some extended woblyness in the bass department. I like how you explain things and how you go in to detail with the sound and what you hear. I really do like the old fashioned style and tube rolling reminds me of changing coffee to my La Pavoni machine.

Would be very helpful if you included the “magic” tube details in the description.

I think that this is such a cool looking piece of gear. I am envious that you have this headphone amp even though I think it is way too expensive. Cayin's A-88T Reference integrated tube amp goes for about $1,900. Maybe if Cayin had integrated a pre-amp section with 3 inputs into the HA-6A so that I could drive a pair of powered speakers or a power-amp, then I would definitely buy it. Now it is just on my maybe-list.

Great review. Thanks!

Excellent review 👏. Well presented. Thanks.

Thanks for your review. Do you mind me asking what is the brand/model of small wooden component rack behind you to the left - the one with the dual headphone stand on top of it? Love the look of it. Thanks!

Great review. I do have the Cayin ha1-mk2 which is also very nice but yours is a definite step up.

Whew... I was worried when you initially mentioned "buyer's remorse". Cayin is a big deal and very well regarded in Asia but a relatively unknown here in the U.S. Not sure why. I almost got a Cayin amp to drive my Klispch Cornwalls (horn speakers) but decided to get pure Class A, made in the USA SET amp instead. .... Cayin's are beautifully made.. .strikingly similar to PrimaLuna and Line Magnetic.. Someday..... maybe for my study once I get into headphones. Would be curious what your TOP 3 to 5 headphones would be as I am a novice. Well done !!!

Well done Sir. That’s an excellent review. Keep going in feeding your passion!

Thanks for the review! Can this tube amp drive Susvara?

Just for understanding: you bought some new tubes and let them burn in for the night and then said "ok burn in changed the sound" compared to the previous setup. Did you tried to listen to the new tubes before burn-in? I guess new tubes are a big(ger) change respect to burn in

You can put kt77 or 6ca7 they're the same el34 give you a stronger bottom end but still with the lush creamy mid-range better than the 88

How is this compare to feliks euphoria?

Hello, did you maybe compare this amp with violectric hpa v 550? which of the two has more power? Thanks for your answer in advance

Where do you buy this? Can you only by directly from the manufacturer?

Thanks for your good video and I fount an adapter (SAT UB-1) that can connect headphones by connecting to the amplifier speaker terminal on etsy.

Thank you so much for this amazing review!! 👏👏

Is there an way that the change was the zmf headphones

very good and comprehensive review. I'm interested in this range of amps too. I'm a HD800S user.

Howe does this sound compared to a Mjolnir 2?

Is this a dark/warm sounding amp?

Great Amp just hart to buy one.

How many DB is it per click of the volume??

I found the Aolous to be very slow on that amp. Compared to a focal clear. Its was nice the mids but just didn't compete on a technical level.

If you had a choice to keep only one of your headphones which pair would you choose?

Most likely the Arya. Check my headphone battle vid if you'd like. I consider it the most balanced

Really enjoy your passion and this was a great review :) Now I'm so tempted to pick this up but might go with the more affordable HA-1A MK2. Keep up the great review's! BTW I really like your rack set up (where the RME ADI-2 sits)...can you advise what model it is? thanks!

the Cayin ha-1a mkii is amazing, when I first got it with stock tubes it did have some hiss but at proper listening volumes it wouldn’t really be there & it was time for a tube change so I went with the genalex gold lions for the main four witch I got on tubedepot.com, I got the 12au7 with balance triodes, I got them matched & the low microphonic, these are options you can choose when on your tubes & for the el84’s I just got them matched & for the 12dt5 I got a nos tube from eBay & it’s the General Electric one, if you jus look up 12dt5 tube you’ll see it & in my opinion it sounds much better & they’re not even fully burned in yet

Nice review! In my main system in my Mystere pa21 amp I use Kt88s which I prefer over the el34s, to me they sounded more tube like. I use the gold lion brand which I feel sound much better than the electro harmonics.

Not yet. I keep eyeing the tube amps in the Head-Fi F/S forum. There's currently a Bottlehead Mainline and a Glenn OTL that I'd love to get my hands on for review & comparison purposes.

That is bad news about audible hiss. Manufacturers often make their amplifiers too powerful.

Update: there is still a hiss, you can definitely hear from switching the HD6XX headphone output from active to inactive. It's still pretty low, but if you set the the impedance to medium then it goes down to an almost inaudible level.

@@MidFiGuy Computer and monitor can cause the interference buzzing too. From my experience the source of buzzing were: Ground loop, DC current, Valves, Poor power and RCA cables, too sensitive headphones, Interference from the surrounding equipment. (Firstly, try to move away from the monitor with separate power connection, /not shared with other equipment). Also can use Cooking foil wrap isolation test (around amplifier) to find the source of buzzing. Play with cables and roll the valves. Good review, looking forward for more. Regards from Russia. Kim

​@@leonidkim3708 Thanks for the detailed & helpful response! So I actually unplugged everything in my room, moved the Cayin on top of my bed with no inputs connected. I plugged it directly into the wall and the hiss was still there. BUT! I found that the balanced 4-pin XLR is the issue. If I plug the HD6XX into the single-ended 1/4" jack then the hiss is virtually gone! You have to really listen to hear it. I don't have a 4-pin XLR cable for the Aeolus which is why it never really posed an issue!

I've been looking for a clean high end tube amp for my headphones. Maybe this or the ZMF Pendant.
