A Question: What makes for Good Vinyl?
"the studio engineer, the recording, the label, the pressing" Wait, what’s about MUSICIANS? LOL it was my pleasure to work on live music sound projects with Jon Ericson, one of Rush engineers..  
Turntable Mats for Technics Grand Class, "G" Series
“….Denon DP80 mat is superior to the Technics mats?" technics mats have less contact area to the vinyl record surface comparing to dp80. also technics mat's pattern does not work well with additional weight.. also, rubber itself seems is a bit fi... 
Best Used Tube Based Preamp $2k Or Under?
@nightfall Luxman CL38uC, or older CL36u  
Turntable Mats for Technics Grand Class, "G" Series
Too bad Technics lost their mojo on mats for high-end TTs! Currently I use Denon DP-80 mat (NOS) on my SL1200GAE.. second to it is SFTG172-01 / RGS0010, original Technics.   
Do military/industrial tubes sound better than regular ones ?
"they should  theoretically sound better” only with tangible sound feedback btw spkrs and tubes, otherwise there shouldn't be big difference, other than aging/storage/etc conditions spec.   
Impedance - The most ignored and useful measurement tool
@erik_squires +1 (again) “I was only posting this to show how an important tool can help audiophiles diagnose their problems.. thanks for pointing to the simple tool to check speakers!  my intension was to emphasize on PA system (amp+cable+spkr)... 
Impedance - The most ignored and useful measurement tool
@erik_squires +1 "You’d be surprised how many speakers have a woofer or tweeter that has stopped working but the listeners don’t even realize it. “ I will be not! speakers impedance is good start, but it will not tell us whole story! whole amp+c... 
Do military/industrial tubes sound better than regular ones ?
@inna "Do military/industrial tubes sound better than regular ones ?”  they don’t! typ. MIL and Industry standards have higher shock-vibe, temperatures spec to comply!   
Pass....Accuphase....or......
"Class A means the output device or devices never go into cutoff.” - definition is correct! push-pull A class amps have bias to cover max current for loads, supported by class a! if load is lower than nominal, one of devices indeed goes into cuto... 
A cable too perfect?
@kennyc "I’m still undecided about getting a cable cooker. Many says improvements. Some cook their cables periodically. " is cable cooking recipe included with those? LOL  
Hegel hum?
You may try to contact Hegel and explain to their technical support staff this issue..? I would return such amp to manufacturer, if no help etc.. Foot away hum isn’t good, few inches could be okay.. I had many amps, and the only accuphase designs... 
ATN160ml Beryllium MicroLine Stylus on AT150e body
@elliottbnewcombjr +1 thx for cantilever info! have you seen boron material info as well?   
ATN160ml Beryllium MicroLine Stylus on AT150e body
@rauliruegas 160ML at 200 pF loading cap resonates @ 16kHz, while 150Ea at 19kHz (ML180 res. freq. is 23kHz). you might know as there is significant phase deviation in frequencies closer to resonance point. I am tuning my phono-Rx resonances to be... 
ATN160ml Beryllium MicroLine Stylus on AT150e body
@rauliruegas dear Raul, thanks for your response! All I tried to explain was a 160ml requires more attention to phono-cable&pre, and using 160ml stylus in 150e body might will work better in some scenarios.. also, subsonic cut-off filter most ...

listen jazz, piano, voice etc, or use Ortofon Test Record Vinyl LP if you’d prefer adv. measurements!
