Audio research and krell
I believe krell added that jumper during the production of the ksa 250, because a certain model BAT preamp was causing DC issues, not all BAT models were a problem just one model if I remember right.  
Audio research and krell
There was a certain BAT tube preamp that had a problem and was putting out DC into amps. I've been running a tube preamp into a krell ksa300s for about 5 years now with no problems.

Anyone try modern 6sn7 Shuguang WE type vs NOS RCA,Ken Rad
This would clear up any issues and I’d be happy to shut up and buy some should they be 600mA   They are 600ma, the only thing you have to be concerned with is if your tube sockets are to close together they might not fit as the glass envelope is...

That is blatant misinformation. It has to be also deliberate as you have clearly read the quote I provided which mentions Mullard (drawing 950mA, by the way). Care to explain to the community? You must have read my post wrong, I acknowledged tha...

The shuguang CV 181 tubes are a 6sn7 drop in replacement, the Mullard cv181 tubes are not they have a higher heater current of 900ma.  
Weakest digital link: DAC - Streamer - Server?
I've heard amps like that in plenty of systems, rooms and different speakers, they all sound bad to me.  
Weakest digital link: DAC - Streamer - Server?
No, the speaker tends to interfere with that, but many come very close. I encourage you to take some amplifiers that identified as such and see if you can tell them apart without looking.     No thanks, those kind of amps tend to give me a head... 
Weakest digital link: DAC - Streamer - Server?
lot of people use amplifiers, tube, many low feedback designs, etc. to alter the tone of their system. Those will definitely sound different from amplifiers designed to be a straight wire with gain.        Too bad no amplifier is a straight wi... 
You Cant Buy It but you Can Build It
I had that little carver subwoofer and it pressurized the room good, but didn't sound very good. My friend has the carver amazings, they aren't built very good and his apogee's blow them away in sound quality.  
The Big Misconception About Electricity
Remember I take this thread at this state as a joke.      Why would you waste your time then? I guess you don't have anything more important to do.  Is this how you spend time off for work.  
Dedicated 20 Amp Line for Audio
A note on 10awg romex.  Yes, the wire is extremely stiff and you may not be able to install it.  You CANNOT fold this wire when pushing the outlet back into the box.  It is just too stiff.  When I did mine, I had to run the Romex straight through ... 
Garage Listing room
It would work if you put something on the walls over the insulation, like drywall or plywood. It will sound dead with just the insulation.  
Science that explains why we hear differences in cables?
Coincidentally there is a recent review in audio science review in which RCA cables from three distributors, with fairly wide price differences, are compared from both a performance and an auditory perspective. No significant differences were foun...
