New TT : Balanced vs. Unbalanced Connection?
You muddy the waters when you mistakenly claim they aren’t balanced. @cleeds  I've not once anywhere on the web made the claim as you suggest above. I think you misunderstood something, since what I posted previously did not contradict this sta... 
Class D Amplifier(s) for SWARM Subwoofer System
@peter_s Why not get the sub amp that Duke recommends? It works quite well (I use one in my system at home) and has the crossover built in and its far less money.  
Does a turntable mat make any difference?
Sota’s mat is also the same durometer and mechanical impedance as vinyl and 1/4" thick. I do not think they sell them separately. @mijostyn SOTA used a platter pad designed by a friend of mine- he sold rights to the formula to them. They never ... 
Good Speakers for Rock and Roll Under 15K
I could not disagree more..  @mofojo Big myths die hard. So this does not surprise me- I get pushback on it all the time. But it comes down to something very simple, which is can you find a designer who can say what parameters exactly will favo... 
New TT : Balanced vs. Unbalanced Connection?
What balanced gets you, mostly, with phono is a few db of gain. I say, residential, short runs: no advantage,  RCA single ended is just as good  as balanced xlr unless your running long spans of cable  @willy-t , @elliottbnewcombjr , @rmd... 
Good Speakers for Rock and Roll Under 15K
It’s obvious that a few here have never really listened to Rock, otherwise they would not be recommending Vandersteen, Volti and other speakers that were voiced with Classical and Jazz. @stereo5  This is nonsense. Speakers are not 'voiced' usi... 
Grounding System Dissection
@davetheoilguy I stay away from these sorts of things. But the equipment in my system all has proper grounding systems internally. I suspect that even if they didn't, a few diodes would be of no help at all.    
Earth (isolated) ground vs. wall outlet ground.
Puritan Audio offers a product Ground Master that requires adding a seperate ground rod that connects direct to the Puritian PSM156 power conditioner. They say it is safe, any thoughts? ’Yikes!’ is a thought...    
Does a turntable mat make any difference?
It does. But the one you got probably doesn't do its job. A lot of mats are intended for DJ 'scratching'. For home hifi, the pad has two jobs: damp the platter from ringing and damp the vinyl from any resonance. If the platter pad is doing its j... 
Good Speakers for Rock and Roll Under 15K
I don't think you are going to be in a room and picturing where the lead guitar is vs the bass guitar.  @willgolf This suggests to me that you've not heard every rock recording out there. I run a studio; we pay attention to where we place instr... 
Harman Kardon A300
@ccogopher 'upstream from the power supply' means the AC power switch and power cord, so I'm thinking you meant something else. The power supply is shared by both channels. So I think the power supply is OK. Since you have a schematic, check the... 
Eliminated my preamp with amazing results
@arhgef There are plenty of switches that can do the job.  
2a3 ?
SETs have a limitation of the greater the power, the less bandwidth is obtained from the output transformer. 7 Watts (300b) is a practical upper limit to what can be considered 'hifi' bandwidth. The 2A3, being good for about 4 Watts, allows the de... 
Good Speakers for Rock and Roll Under 15K
@gregjacob Its actually a myth that a speaker can be good for one genre of music (rock) and not another. If your speakers aren't good for rock, then they are likely weak with jazz and classical too. Put another way, no-one has ever figured out a w... 
Best Vintage tube amp / preamp manufacturer
@koh_i_noor If you like the old ARC stuff (like the SP-3) then if you can find an H/K Citation 1 and have it refurbished you're in for a pleasant surprise. The weak bit about the Citation was its connectors (which were the only game out there at t...
