Looking for a tube preamp that has xlr outputs.
I agree, It is also AES48 compliant. @ditusa To the best of my knowledge, it isn't. There are only 3 ways to comply with AES48; output transformer, a solid state circuit specifically designed to allow a floating output and the system we patente... 
Solid State Power Amps
@sgordoxyz Is there a reason you want to spend that kind of money? Just because you did does not mean the amps you get would actually sound better. There is something called the Veblen Effect, in which people will spend more under the illusion the... 
Looking for a tube preamp that has xlr outputs.
@dlowman There is a standard used in balanced line applications which is AES48. If the balanced line equipment supports AES48 you'll find that the interconnect cables make little or no difference in your system and you'll also have immunity to gro... 
Watts! How many do we need?
Thanks for your comment, but I am pretty sure I understand current and how it relates to solid state amplifiers performance characteristics. Sorry, but the article you refer to is so poorly written as to escape making any sense to me, hats off to... 
Transfiguration Phoenix S cartridge - impedance loading recommendation?
@toronto416 I ran that cartridge for many years. It was plug and play; my phono section has a 47K Ohms input (the industry standard for all cartridges). The only reason you might need loading is if your phono section is bothered by RFI generated ... 
PREAMPLIFIER UPGRADE QUESTION
@kjl1065 If you are planning a balanced line preamp, its a good idea to ask if the balanced preamp supports the balanced standard, AES48. The reason this is important is the balanced line system has several goals amoung which are elimination of gr... 
Watts! How many do we need?
From my experience with solid state, current was the primary determinant if the amp was up to the task, the more the better. From my tube amp experience, it is far, far less important. So I went from high current 350 wpc solid state to 70 wpc tub... 
Solid State Power Amps
JA: "The Focal will play loudly when fed only a few watts, my estimate of its voltage sensitivity being 89.2dB/2.83V/m. However, as fig.1 shows, the Sopra No.3 is a difficult load for an amplifier to drive, with a minimum magnitude of 2.75 ohms a... 
Push-pull Tube Amps and autoformers
@mrdecibel Yes, that comment was not directed at you.  
Push-pull Tube Amps and autoformers
Ralph, can you point me in the direction of someone using a beefy solid state power amplifier that are using the Speltz zeros, so I may hear from them their opinion. @mrdecibel Yes- talk to Steve McCormack of McCormack Audio. Perhaps Autoform... 
Which has a greater influence on sound quality, the amp or the preamp?
@atmasphere wrote "you hear distortion as tonality" Could you explain? Thanks! @o_holter Our ears use harmonics to tell the difference between a clarinet and a trumpet. When harmonics are added to a signal (such as when that signal passes throu... 
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...
