1101 Audio custom crafted headphone amps
Apr 17, 2021 at 5:27 PM Post #691 of 1,281
FYI - for Blue Halo owners - I can’t get enough of the Foton 6n6p tubes. The ones I’m using have square getters and they are dead dead silent. Get some adapters and go get em!

Seems that some of them are going up in price a bit. LOL!

Also, Schiit will be releasing an amp that uses 8 of these puppies in the near future, so best stash up now. :smile:

The first ones I got cost $2 incl shipping but that was 10 years ago...
Seems the the box anodes with square (dimpled) getters are becoming few and far between. Lots of cheap ones still out there from other factories and later years, but I'm assuming the square mica Fotons are the preferred ones.

Thunder into the Abyss. Gets a big thumbs up from me.

Mischa says 2.2 watts into 50 ohms with this amp (and says good job I asked for those massive 170uF output caps!). The Abyss are 47 ohms, so near enough.

Using this amp, can you switch between different drivers instantly, or do you have to wait for the different drivers to warm up?
Need to switch the amp off. Wait a minute. Then select different driver. Then turn amp on again.

Congrats. Will be getting mine soon to partner LCD4 and He1000se.
I've only had a few hours on the Abyss, but I think you'll find they compliment the LCD4 quite nicely. More thoughts in a few days. I've been keeping my eye on the local used market, and a pair appeared. Don't think I've ever purchased a new set of full sized headphones.

I've found the LCD4 pairing very well with my 300b amp. Several years ago listening to the then original Abyss 1266 phi with Woo Audio WA5le and Takatsuki tubes was also a very good outcome.

If you find a very good condition Abyss why not but I'll be getting new. More like end of year timeframe though but these timeframes have a notorious way of getting shorter for me. The LCD4 and 2 tube amps are very recent purchases.

I must say that is a great picture of Abyss on Omega stand on top of your tube amp.

It’s a masterclass shot that only the Sennheiser HE1 can compete.

Thanks! But honestly it was just a quick snap with the phone.

Just saw this. That’s a great coupling.

Your next custom amp will be even better.
It's probably not going to be better. Smaller footprint, different design, hopefully passes the WAF - as we'd both like this headphone amp in the living room. And I certainly don't have any more room upstairs for a 3rd headphone amp.

That's a beast of an amp. Very nice! I'm going to be joining the 1101 Audio club this year myself. Really looking forward to it!
