Question About Capacitor Upgrade in Tube Amp

Yes given the cost of the map I did not want to spend too much on the upgrade but honestly I do not think it could sound any better. Bass, middle, and treble are all clear and in balance with each other. 

I am sure all the other caps recommended would have made a significant improvement as well. Maybe with just slight variations in bass or treble response. But the difference from the original cheap factory caps was much more than I had expected.

On SET amps the key here is not just Caps, resistors and etc but the trannies are the keys elements which will make the amps sound best.   To me it doesn’t make sense to put a $500 caps ( duelund)  on a $1k amp, You are not going take or make that amps sound like a $10k amp. Yes improvement, for sure there would improve compare to the original parts but to what extent, cost and time?  So to summarize it up i personally would not spend so much on caps upgrade unless i know what trannies that are fitted on the unit.

Does anyone compared directly:

1. Vcap CuTf vs Mundorf Supreme Silver Gold Oil?

Vcap Cutf is in the class by itself if untilizing in electronics application. If you are using it for speakers then the Mundorf SGO is a much better cap on speakers.

The amp comes out of the same factory a Cayin and PrimaLuna. I have seen it reported that there is some amount of sharing of parts. The transformers are indeed decent.

For the Muzishare amps they are made in the Line Magnetic factory. And once again some comments online and photos indicating identical components being used.

Electrolytics are Nichicon so just for the Willsenton they cheaped out on the coupling capacitors.

In a break-out box, I have compared V-caps with Solen teflon f&f  and Relcap teflon f&f. The latter are good and quite similar IMO, and the V-caps are bright. To my ears, in my system, in my comparison. YMMV.
