p.s. and two for the Passeq so far?
Just the 2. By 'new' I meant the 2016 model. I edited my post to prevent further confusion.

Well about the Spl PQ, at the beginning it was the model 2050, with motorized pots and presets/recall function. Then they released a "recording version" wich was basically the same without the motorized pots and all the logic circuitry etc.
Now they released an updated version of the PQ with an updated design wich "cut down" the production cost overall.
I did listen to the newer model and, if I remember correctly, it was a bit more "open" or let say "present" in the midrange, and "less" warm in the low / high area. The power supply is quite different from the original design aswell, so that can change a lot of things about how the unit sounds etc.
I'll do a shoot out with smoothtone files to see if I hear the same thing

i was curious how the Tube Tech HLT2A would sound if I only replace
the two nr.1 tubes, as the developer is of the mind that only these
two would provoke a tonal alteration (ref. Teebaum's earlier posts).

So I replaced the two 1st Tubes (L/R) with
Mullard M8137, as I had great experiences with Mullard,
when I had the Thermionic Phoenix "11th anniversary edition".
(although it uses another Mullard M-Tubes).

interesting!

the sound difference is huge, you can't imagine that you used the same setting.
the original tubes sound snuffy, the mullard much more open, whereby I would like to listen in again tomorrow with fresh ears, the brightness could also come from more saturation.
the version with the mullards also seems to be much louder, something that is not confirmed by the measurements, but rather by the brightness and possibly by saturation.

your sound sample makes it a bit difficult for me to clearly recognize saturation, moreover, it is difficult for me to estimate the punch and lowend range of your sample.

i ordered the same mullards after your mail and now these new cryo-tubes from jj.
i will make a comparison of all diveser tubes to find the optimal combination for me!

yes I'm really amazed!

With the Mullards, the hammer acts more like that huge Steinway that I've recorded ;- ) : more weighty, with a bigger body, more open. But you're right the punch is not that obvious as it would be with drums or even bass guitars etc... so I am looking forward to listen to your test results.

And the Mullards reproduce the dynamic, spatial and tonal complexities better in busy/congested musical moments: better resolution specially in the mids.
Or maybe the original Tubes are not just the right ones for this device!

I just can say, it was a great investment to buy both the TubeTech and these new Tubes, thanks to you Teebaum.

* update: the mullards sound even better after a short break in (4-5 hours only).
** update 2 after several days: the already very good tt stepped a new level of quality with the M8137 (or maybe will with any other good tubes as well, except the original ones). Besides other improvements in the mids and basses, the Highs are now like a sweet dream.
