Seriously considering tube preamp…opinions?
but I'm completely in the dark about what your stuff costs.We make a 6SN7-based preamp that as a line stage is $1900.00.@hilde45The line stage of my prior comment above is the UV-1.  Were you planning to run a balanced preamp or single-ended (the ... 
Seriously considering tube preamp…opinions?
One parameter is budget. Is this Atma or Ear in the neighborhood of $3k?@hilde45  We make a 6SN7-based preamp that as a line stage is $1900.00. It is single-ended. We also make balanced preamps (and were the first to do so) but they retail for mor...

Atma-Sphere MP1 with single-ended inputs and outputs? Adapters OK?
@luisma31  Tie the shield at both ends, or only at one end. If only at one end traditionally that would be at the preamp end, but you'll find its not of much concern. What is important though is that pins 1 and 3 are tied together, and that connec... 
Class D amplifiers have very little phase shift
but that is horse chasing after barn doors are open, and there is always a better way.Sorry, I can't make out what you're trying to say here. 
Class D amplifiers have very little phase shift
In a self oscillating class D amp, the feedback itself is used to correct phase shift. Its pretty effective in this regard.But I've been listening to a class D amp with zero feedback, switching at a fairly low frequency (400KHz), with a rather con... 
Low-sensitivity speakers — What's special about them?
What it comes down to is... really good mids with any type of top end extension without cone break up is hard to find in true high sensitivity speakers.The Classic Audio Loudspeakers use a beryllium diaphragm with Kapton surround in their compre... 
Best Value Line Stage Tube Preamps?
Given that very helpful clarification, what would be your optimal components for a balanced line electronic chain (source - preamp - amp)?Optimal? The sky is the limit... I prefer analog, and since all cartridges are balanced sources, I would pro... 
How to guarantee to lower noise- ground loops in your system
What many people don’t realize no matter how good your equipment design is if you are feeding ground off the same circuits you can pickup noise @audioman58  This actually isn't universally true. Its only true if the audio equipment puts current th... 
Looking for a plenum-rated balanced cable that won't require a second mortgage
https://www.redco.com/Carol-E2102S-Plenum-Rated-Balanced-Install-Cable.htmlMake sure your gear supports the balanced standard, else this **might** sound pretty dreadful.  
comparing two pre-amp/phono section buying scenarios, so weigh in!
If I were to stay with the CJ line section I'd simply have the CJ phono section installed. An internal phono section doesn't have connectivity problems (if you've ever heard how an interconnect cable can change the sound then you know what I'm tal... 
Low-sensitivity speakers — What's special about them?
Generally speaking if you do have to play the speakers at volume, lower efficiency speakers have something called 'thermal compression' where the voice coils can heat up, significantly curtailing musical peaks. But if size is an issue and your roo...

For that kind of money you have a lot of options.Do you have or are you planning a low output moving coil setup? 
How to guarantee to lower noise- ground loops in your system
Yikes! a topic like this certainly brings out a lot of ... stuff.It is this simple:1) the house wiring should be to code2) you will not experience a ground loop unless your equipment has a grounding problem. Despite an enormous amount of informati...

Any particular reason you are stuck on that preamp?
