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... 
Harman Kardon A300
@ccogopher Before you go to a tech you might compare the working channel against the bad one. I hope you have a schematic!! Have you been able to sort out if the weak channel is in the power amp section? Or does it occur further upstream? Do th... 
XLR to RCA conversion
the specific model he recommended isn’t available.  That’s why I posted. He recommended the Jensen PI-2XR. @hifinut51 I know someone that bought that exact ISOMAX unit only 2 weeks ago. Did you talk to anyone at Jensen?  
Using PA Speakers In A Home "Audiophile" Application!
@ditusa Its worth noting that my drivers use a beryllium diaphragm (as you probably already surmised); the driver is also modified to run a field coil. As far as I'm concerned, JBL knows what they are doing with their horn structures- I've seen no... 
Analogue clipping from digital sources
but phono stages have additional gain just for them.  It's true that you almost don't need any gain for CD's, but tape decks and tuners were often near that, no?  @erik_squires No. quite often a tuner or phono section will make 1Volt. A cassett...
