The JPS Labs: Abyss AB-1266 Impressions Thread
Nov 17, 2020 at 1:33 PM Post #12,826 of 22,434
or go for an good quality stereo integrated via the speaker taps. cheaper and mostly better in my experience. and yes, i have the 1266 too and tested a lot of different amps :)
I've tried a couple integrateds. My issue on both was too much gain. Hardly had any play with the volume knob before things got too loud. Made sense to me, since any integrated is made to output at much lower impedances than headphones. So IME, this is something to consider. One cannot just get any integrated and assume it will work.

I'm not sure they provided any qualifier with that statement. As long as you're reasonable, you'll be fine. As well, as long as the amplifier is competently designed, you'll be fine.

I've tested the Abyss with the Pass Labs INT-150 at full volume which is about 10W. I've attempted conversely with my Kevin Gilmore CFA which outputs 16W but the levels were severely ear deafening so I wouldn't be too worried as long as you implement good practice as has been the case, for example, with the HE-6 on integrated/power amplifiers for years.
My single Chord Mezzo 140 is 120W per channel into 8 Ohms and my twin mono blocked Chord Mezzo 140's are 240W into 8 Ohms.

Right. Now consider the 50 ohm impedance. Do the math of 22 watts. Plenty headroom. Also consider how much of that output is Class A.

The point being, you are perfectly fine.

Thank you for your feedback paradoxper. Much appreciated. If I can get away with using one Mezzo 140 (being very careful with the volume controlled by my Chord DAVE) with the 1266 this would be great as the sound from them to my Focal Electra Be Speakers sounds fantastic.

I think you'll find speaker amplifiers level up planar drive, say, better than 96% of headamps out there.

Good luck on your journey!

Being so absorbed with researching into TOTL Headphone Amps and the Abyss 1266, I realised about 10 mins ago that when I had a pair of HiFiMan HE6's (about 2 years ago) I used my Mezzo 140 connected direct from the speaker taps with a cable made up for me from CustomCables in the UK. Sounded pretty good. I couldn't listen for long though due to the weight of the HE6's and having quite a small head, they were also very loose fitting which didn't help !

I'm thinking about upgrading my Topping A90 to a tube amp. What are some of the good tube amps that can bring out the most out of 1266 TC, is Woo Wa33 the recommended tube amp to drive it? I also have heard good things about the pathos tube headphone amp. Not sure which one is better.

Yeah, the wa33 is a recommended amp. Several of us have it. You can even get JPS aluminoy wiring as an option.

Has anyone tried any new EQs lately?

I'm quite liking this one. It's from the one posted here a while back, with slight tweaks, and I added high and low shelves.

Congratulations. Enjoy. Now get off the keyboard and start listening 😁
