Push-pull Tube Amps and autoformers
with your particular tube amplifiers you do not need the Speltz Zeros, as I am surprised Ralph is saying it is ok. They were created for OTL amplifiers. @mrdecibel The ZEROs can really help solid state amps sound better driving lower impedances... 
Tube preamp topologies and music
@gochurchgo There are now class D amps that have the same distortion character as the best tube amps (but lower overall). Distortion is why tube amps sound the way they do, just as distortion is why most solid state amps sound harsh and bright. Pu... 
Which has a greater influence on sound quality, the amp or the preamp?
If your preamp or source is lacking, it will not matter how good your amps and speakers are- they cannot make up for signal loss or coloration! The preamp has to be right! Amplifiers tend to have the most distortion of any of the links in the ele... 
Futterman. Jump in? Or, not so fast...
All 16 matched 6LF6 tubes (that were running at about 65% of their original strength) have been replaced with a new matched set NOS 6LF6 tubes. The dozens of photoflood caps, which were about 1/2” x 1”, not as atmasphere described, @unreceivedo... 
Push-pull Tube Amps and autoformers
@audiodidact I think the best way to use the ZEROs is to use the 16Ohm taps on your Quicksilvers if they have one. Then use the ratio on the ZEROs that seems to sound best. Keep the speaker cables as short as possible and as heavy as possible bet... 
Magnepan LRS plus & Atma-Sphere digital amps
@izzy2 Our local dealer demos the LRS + with a set of our class Ds so I guess it works OK. Unless your room is exceptionally large it should be fine otherwise. The LRS+ doesn't seem as power hungry as some of the larger Maggies.  
300B or 2a3 SET Class A for Heretic Model A?
Due to the good impedance and DB of my new speakers, how would compare a proper SET 300B Class A to small EL84/34 based tube integrated such as Leben CS-300Xs, Luxman SQ-N150, Mastersound Dueundici, etc. @superelmar That will depend on how well... 
Not sure what to think
Alas, as much as I still have a passion for the McI for the non-auditory reasons above, for the moment I will be sticking with my Krell. @olfac87 The distortion signature of any amp is its sonic signature as well. Obviously not a lot of differe... 
300B or 2a3 SET Class A for Heretic Model A?
@yaluaka I am very focused on the sound; if its right then the music is processed by the limbic portions of the brain which increases body movement and emotional response. Increased engagement. I run a recording studio as well as manufacture am... 
High end Class D amps?
3 1/2 yrs later, I could not resist.  Of course there are Class D amps out there that are "just as good" as Class A amps....just like there are Hyundai autos out there that are "just as good" as a Ferrari.   @jymc Ferrari was founded in 1939. I... 
audible distortion and tube gear?
@immatthewj The designer of the CD probably didn't understand what makes distortion audible to the ear. So they probably just added harmonics to the signal without doing anything else. One of the things that makes distortion more audible (especia... 
audible distortion and tube gear?
I know that I have read on this site about "tube sound" having something to do with the way tube gear handles distortion, but would tube gear make it harder to recognize distortion? @immatthewj Perhaps, depending on how much distortion your amp... 
300B or 2a3 SET Class A for Heretic Model A?
To me this is also a specious point, the idea of accuracy in recorded reproduction. I’m looking for something I like. I don’t want a stereo limited by only sounding good with any particular music or record label. It’s not about accuracy, to me ac... 
Vacuum Tube preamp with my KRELL KAV 250a, a no no......WHY?
Does your direct coupled preamp put out a DC surge when it turns on? If someone has their direct coupled solid state amp on and you turn on your preamp.....could it blow up the amp? Long ago, I had heard that your preamps could blow up things (is... 
Vacuum Tube preamp with my KRELL KAV 250a, a no no......WHY?
I have an older Krell KAV amp that has been recapped and refreshed.  A technician that I respect very much said do NOT use a vacuum tube preamp with my KAV 250, or any other Krell amp for that matter.  Can someone with more technical knowledge th...
