Quicksilver Audio Headphone Amplifier any opinions?

The 1/4" connector is pretty serious on the Quicksilver. Compared to everything else I have, it REALLY holds on tight, it takes significantly more force to plug and unplug my headphones, which I do ever time I listen.

It's tight to the point where I'm concerned about excessive wear to my connector ends. I have a pretty expensive cable and would hate to wear it.

Perhaps there is a good 6" extension that I can just leave plugged in so I have a "softer" fitting?
Can you buy the extension from the same cable maker, using the same cable materials? I personally wouldn't want to introduce anything potentially inferior into the chain. That is, if you care about cables, which sounds like you do :)

I leave my headphone cable plugged into my Quicksilver all the time for this very reason.

Gold Lion 12AX7s just came in (now paired with my Gold Lion 84s), the highs are brought up vs the Mullards and it's noticeably punchier. It tightened up the bass even more so it's very close to my iFi Signature. Still not as "3D" as the original JJ/ Mullard tube combo, though that might be partly because the highs aren't nearly as elevated.

Since these tubes are brand new with just a few hours on them now, I expect them to change as I put the hours on.

Tungsram EL84s (foil disc getter) & RCA 12AX7s (black plate) help to bring out the best of PS500e…

Since I have a headphone measurement rig I decided to throw the ZMF Verite's on and compare the raw frequency response of my iFi Signature to the Quicksilver (with the Gold Lion tubes).

I expected some deviation but the result surprised me:

Exactly the same! (Brown & Blue line)

It's crazy how they can sound so different yet measure with the same tonality.

Someday I'll measure the stock tubes vs these as well.

*** What does that tell you about the sonic veracity of frequency response graphs?…

They measure almost exactly the same. Ergo, they must sound exactly the same. Audio is way easier than I thought!
