Why the woofer moves badly when playing certain LPs
A certain amount of very low frequency woofer excursion with records is perfectly normal. Just to be clear, my signal chain has 2Hz response from the cartridge input all the way to the loudspeakers, which employ dual 15" drivers. I run them withou... 
Probably the most High End DJ Mixer ever made...
There's a guy here in town named Mark Balma that is building all-tube mixers that look very much like RCA tube studio mixing consoles from the 1950s. They look spectacular! 
Phono stage for 0.2mv cartridge?
One thing that isn't mentioned with gain specs is the noise. A preamp with 70dB might be noisier than one with less gain (although certainly one would hope its the other way 'round). Based on the descriptions here it sounds like one phono section ... 
Why the woofer moves badly when playing certain LPs
One fairly simple explanation for the complaint is the cartridge has compliance too high for the mass of the tonearm.  
Why the woofer moves badly when playing certain LPs
@mijostyn  I highly doubt that mastering lathes are to blame- too much is at stake! I have yet to buy a new LP and run into anything like this; OTOH many of the new LPs I've bought seem to have deeper bass than many of the older LPs (I like electr... 
Separates or Integrated? What makes more sense?
Separates allow you a lot more flexibility and greater resolution. They allow you to improve your setup incrementally, which is great on the budget!In the resolution department as an example, you can keep your speaker cables short by placing the a... 
Phono stage for 0.2mv cartridge?
  I am looking for a quality phono stage with at least 72db of gain. During this last year I obtained a Canary MC10 which sounds beautiful but I am somewhat volume limited and listen at such high volume control settings that tube rush has beco... 
It looks like a debate to me.
I stand by the intent of my original statement:Amps seem to sound more sensitive to impedance issues to me than the math otherwise suggests. @erik_squires I was not contesting this, FWIW. There are far far too many other factors at play including ... 
Futterman. Jump in? Or, not so fast...
Harvey worked with Mr. Futterman before the latters passing, and bought the rights to the Futterman name and OTL design shortly before that came to pass. One of the reasons the NYAL amps were unreliable was Harvey used surplus photoflash capacit... 
Best 6NS7 Preamp for a Pass Labs XA25 amp
IMO/IME the 6SN7 is one of the best tubes you can use in a line stage of a preamp! 
It looks like a debate to me.
I will argue that we are also more susceptible to damping factor and speaker/cable impedance than we think we are, but I, in a very lage part, agree with Ralphs point, that the distortion profile is probably a large, large factor in likeability... 
It looks like a debate to me.
Since I was not invited (for good reasons as you will see) to the seminar I'll just make this post- It should not be a debate. If you have a tube amp that 'measures poorly' yet seems to sound just fine (as has often been seen in the pages of Stere... 
Seriously considering tube preamp…opinions?
@hilde45  with the Salk SS 6M you will only need  about 1/4 the power to do what you were planning before. 30 to 60 watts should be very nice on this speaker provided you are not too far from them in your room.That speaker seems to be quite tube f... 
Futterman. Jump in? Or, not so fast...
The Futterman amplifier proved to be the main impediment to our running a business. This was simply because the circuit (especially under the Rosenberg/NYAL name) did more to convince audiophiles that OTLs blow up more than any other topic (analog... 
Balanced to RCA
NEVER short pin3 to pin1 on a balanced XLR output.@danip   If the equipment supports the balanced line standard then this should be no worries at all. But it is worthy to note that most high end audio equipment and a fair amount of studio gear doe...
