What are those hefty tubes in the QS?

In the front are 2 RCA 5751 1960's Vintage Black Plate Audio Twin Triodes and in the back are 2 Hammond branded Holland Amperex

The 5751 category, at 70x gain, is an excellent tube for the QSA. A ‘holy grail’ of this category is the Raytheon 5751 ‘windmill’ getter. [This is fantastic in Icon Audio HP8.]

Oh man, I wanna try that! Will for sure look for them. Great suggestion!

Recently upgraded to a Dangerous Convert-2 Dac.
Truly blown away by the performance with this Amp and Dac combo. Thought I'd also add in a picture of my shelf:

This is one of the best cat shots ever ... a beautiful cat, plus they all seem love warm, dark places.

My bankruptcy attorney thanks you for this!

…a new Dr. Seuss title? CAT on a DAC in a RACK.

Response #3 : a purr-2-purr DAC?…

My bankruptcy attorney thanks you for this!

…will payment-in-kind fit the bill?…

LOL I never even realized!

What on earth constitutes "in kind payment" for a bankruptcy attorney? (my mind shuts down when I try to think about it).

….perhaps the BA will accept ‘debtor-in-possession’ first lien status post a tube-driven Chapter XIII filing……

Ordered one of these a few days ago as a present to myself. Arrives before Christmas. I spent time clearing out non-essential gear to make room. This is my first “real” tube amp (Vali 2 being a hybrid), so I’m looking forward to the experience.

Chain will be Gungnir MB > Khozmo PreAmp > Quicksilver > a variety of HP, including OG HD650, K601, DT880. May try Elex, AH-D2000, and some others.

It should compliment my Auralic Taurus MkII.

Congratulations @luckybaer, I hope you enjoy it as much as I enjoy mine!

The QSHA arrived and is safely set up on my second rack. Oddly, it shares a shelf with a Parks Puffin - strange bedfellows, indeed.

I’m enjoying the music and am not doing any critical listening or analysis. Importantly, I don’t find anything wrong with how it sounds or functions (thank goodness). All I can say is this: with the OG HD650, it provides a pleasant, non-fatiguing experience with more than enough dynamics, detail, resolution, etc. to keep my toes tapping and to keep my mind on the music and off of analysis.
