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?  
Amps Atma-Sphere M-60 Mono blocks OTL design
@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... 
Why Single-Ended?
How much potential sonic performance would I lose by using my SE preamp into the unbalanced inputs of a fully differential amp? e.g., my UV-1 preamp into the SE input of an Atma-sphere amp, or using this preamp with a Pass Labs amp.If using our... 
Why Single-Ended?
I'm not knowledgable about how you  configure your circuits but I'm thinking you do not float the signal from input to output so eventually the signals do get referenced to pin one.We try to avoid referencing signal to ground as much as possible... 
Watch out boys,there's a new game in town!
I can think of a few engineering bugs built into that but that does not change it being kinda cool. One bug is no platter pad so no vinyl resonance control as the needle tracks the grooves. Another is the short arm length which is problematic for ... 
What are the best speakers for 80's hard rock?
In my example contrasting MBL vs Soundlab, it was not my intention to suggest that Soundlab would fo a poor job with Van Halen.   It WAS my intention to suggest that the big MBLs would do a better job (at least to my taste).  The delta is proba... 
Speakers for electronic/hiphop/rnb [$4000 range]?
Speakers don't care what you put through them. Classical music is pretty demanding- what works well for that works well for hip-hop and house as well. That a speaker is good for a particular genre of music is one of the longest-running myths about... 
SET 45 Amp Driving Dynamic Speakers
I thought 45s made 2W and one should run them at under 1W draw to keep distortion from growing much.Is this what you mean by 0.75W?You can get 2 watts out of them but if you really want to hear what they do its a good idea to run them at a lower v...
