The best coupling caps in power amp ?? Mundorf, Infinicap ??
No; but if you've handled a Teflon cap, then unless it was hermetically sealed you probably changed its value. You won't see much in the way of physical deformation though.  
The best coupling caps in power amp ?? Mundorf, Infinicap ??
We've been auditioning coupling capacitors for close to 40 years now. The current king is the V-Cap copper foil Teflon; it is both neutral and extremely musical.As far as musical goes we've heard some extremely good paper and oil types but the pro...

Tube Watts Vs. Soild-State Watts?
The watts are the same.In the end as much as we audiophiles hate to admit it, its all about what distortions exist and how much.Tubes tend to have higher amounts of lower-ordered harmonics (which sound like 'richness' to the human ear). Transistor...

Where's a good source for Russian and Chinese 6AS7?   We stock both and both are available on ebay.Usually when we ship a set of amps we precondition the tubes first and then play them. In this case since the amp was used it came with its own tube... 
SS preamp with tube amp
If you got that Mac a good price, hold out for a good tube preamp at a good price and then see what you think! 
Help needed with Tube Audio Design (TADAC)
If the XLRs are male then they are outputs. If female they are inputs. Did you set the input switch to the correct position on the Hegel?

@ozzy ,The Tung Sol name got bought out a few years ago and is now being used to mark Russian-made 6SN7s. Usually these are the same tubes as the Electro Harmonix but with a brown base. They are nothing like the old-school Tung Sols which were a n... 
SS preamp with tube amp
IME transistors don't do the low level detail thing as well as tubes. Fast yes, but low level detail, no. So I figure tubes in the front end and a solid state amp if you have to have solid state. The idea there is if the signal source gets messed ... 
Why Single-Ended?
Yes! It brings the shield into play as part of the signal. IOW its not just for shielding any more. As soon as that happens, then the cable imposes considerably more artifact.  
Parallel SET with sufficient power
@georgehifi , there’s more to it than that... generally speaking, SETs behave as power sources rather than voltage sources (which might be your typical solid state amp). The reason to go this route is to avoid the brightness and harshness often as... 
Parallel SET with sufficient power
@ normie57,You might want to read this; it will help you understand the issues of driving a speaker with various kinds of amps.http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpIf you are planning to use an SET, the speakers yo... 
Why Single-Ended?
^^Just FWIW, star grounding is nice but the real issue is how the chassis and circuit grounds are handled! 
I've decided to try Tubes

Fuse and Power Cable improvements 'how'? - Nuprime ID-8
Coming previously from a B&W 805N paired with Yamaha amp, so far my listening with my Kudos C2 with Nuprime is that while female vocals play loud volume wise, singers like Adele and Whitney Houston sound like they ran out of lungs (lack big...
