Tube Amp, Preamp upgrades -- what did you do that improved your units?

How about upgrading transformers?

Do QuickSilver amps have high enough quality transformers and they don't need to be replaced?

Hilde45,

I believe a call to QS is worthwhile. You tell them what you're looking for in sound production. Tell them your system. My guess, your room has as much to do with your dissatisfaction. That aside, QS will give you insights, regardless of getting their ego bruised. It's worth hearing their opinions.

You've received lots of opinions in this thread, which probably has left you with more questions than narrowed your choices for the right direction. I agree with your price point perspective. Lean on that with QS. "I'm assuming this amp was built to a price point, which makes perfect sense. If the price point was $500 higher, what would you have done differently with this amp to improve it, not essentially creating a new amp? Second question, do you offer these upgrades in-house?"

Those questions offer respect and acknowledgement of their intentions of quality. You also lean on them for their opinions and technical expertise. If they still get bothered, then you go elsewhere...I doubt they will.

Send me a pm here and we can talk more if you want.

Goodluck

I found a great improvement to my tube amp was to buy a power conditioner this made a big difference! I bought one for like $500 and it worked great!

I have benefited from other people who have had experience with asking them about this question. It is denied that anything needs to be improved and there is definitely a lack of sympathy for the question itself. 
 

the room is not the issue. The thread covers these things already.

No on upgrading transformers. They are good, high in quality and function.  

The bones of the amp, circuit, transformers, sockets, point to point wiring, is solid. Not naming the transformer manufacturer, they are quite good in stock form.  More spec info available in reviews. One of the reasons I bought the amps, powering my larger custom 4-ohm 92.5 db speakers. The amps don’t even break a sweat. Nor do they run hot like many of my former tube and SS class-A amps did.
