what made you decide to sell yours?
All my other amps I currently own are superior.

The zahl HM1 is my main solid state amp now.

Must be quite the headphone amp then. I had a brief listen to the McIntosh MHA150 using 800s and 1266 TC, I much preferred the Form S/ Powerman even though it was cold.
The formula s/p is a very good amp, it was my fav solid state amp for 1266TC, the HM1 is just better at pretty much everything.

thanks for the response, very interesting, do you see yourself reach for wa33 more or zm1 more for the abyss? you have quite the variety, I am sure you are very satisfied.

Formula S/ Powerman has really good synergy with Utopia 2022. I was considering selling Formula S/ Powerman before, but I decided to try it with my newly arrived Hugo TT2 and compared it to Enleum Amp 23R. FS+P opens up Utopia 2022, the treble is more lively and extended compared to Amp 23R. This makes me change my mind on selling FS+P. Now preparing my wallet to get M Scaler.

If one owns the abyss 1266 TC it is hard to do much better than the formula s/powerman for what a used pair will cost you today...I am using my CFA3 which has far more power with my abyss and it is outstanding but I really only need the extra power for the susvara ...I think the formula s combo is outstanding

They are honestly both amazing and its a struggle choosing between them and it depends on my mood and genre of music i want to listen to. For strictly electronic music i think the HM1 is superior due to its grip, speed, slam and faster transient response but the WA33 is no slouch. For most other musical genres i think the WA33 is superior, for a tube amp it slams REALLY hard but its its the tubes that really make it more musical than the HM1 for me, everything just sounds more real especially instruments and vocals on the WA33 plus it sounds more open and better space between everything compared to HM1.

When i listen to the WA33 with 1266TC then go back to the HM1 it sounds a little flat in comparison, I truly believe tubes are the way and having a tube amp or tube pre in your system is the way to go for 1266TC. The WA33 is extremely hard to fault with 1266TC, it is not lacking in any technical aspect apart from not being tubey enough for some people (this is the main complaint alot of people have about WA33).

If i had to choose one or the other for 1266TC overall i would keep the WA33 as its synergy with 1266TC is absolutely incredible.

Interesting, before I bought the Formula S I was looking for for user impressions of comparisons between the Enleum 23r or the previous Bakoon version and the Form S/Powerman.

My DAC is tube based so I guess that’s why I don’t prefer a tube amp as I crave the control that the Form S/ Powerman gives. I’m currently using the grado rs1x on the Form S/P and absolutely loving the combination. I only need to use the low gain as the grado headphones are very easy to drive.

I think I've changed my mind too on M Scaler. I spent last night playing with HQPlayer and eventually I bought one, I can hear an improvement with HQPlayer. Not every setup will hear a big improvement, it will depend on the audio chain. In my case, I can hear a dramatic improvement on Terminator Plus+WA33+1266TC, but not so much on my other setup, Hugo TT2+FS+P+Utopia 2022, the improvement is still there but not quite dramatic.

Instead of M Scaler, now I want Holo Audio May KTE.

I think the problem is finding one. From what I can tell they dont seem to pop up very often, or when ever I stop looking they popup and I some how missed it. I use a K-Dac and Broadway now but I finally got a Sagra and now im going to have to start searching for a formula s to pair with it. For now though the broadway will suffice when paired with my DTC

Will be curious to see what they put out. This would also some what explain a response I got back from a vendor about considering upgrading K-Dac / Broadway to Sagra / Formula S which was well if you dont have 1266 yet focus on cabling before moving to Sagra Formula S. unfortunately I didn't listen because I found a great deal on a Sagra and went for it.
