Tube recommendation for Audio Research LS-2b?
Yes a large '253' is etched vertically near the top. The orange labeling is easily scratched off, however. 
Tube recommendation for Audio Research LS-2b?
I have an LS2B-MKII and have compared the stock Sovtek 6922 with an Amperex 7803 (PQ/Orange). The Amperex was much more detailed but added a slight sibilance. I'm not sure if the tube was the issue or whether the preamp needed a bias adjustment. (... 
Cheap Interconnects from Hong Kong
I found this thread after seeing a massive assault of XLO speaker cables from Hong Kong on eBay. Having owned (and still owning) a number of XLO speaker cables the fakes are just obvious to me. It reminded me of the book 'Blink' - trust your intui... 
Hum from Grado on LP12.. Better carts to consider?
Thanks Atmasphere and Snfrosten. I will take my LP12 to the Linn dealer and ask them to try it on their system. I'll keep you posted. 
Hum from Grado on LP12.. Better carts to consider?
Thanks everyone. Does anyone know how to attach a ground wire to a Linn motor? I'll ask my Linn 'mechanic' but I can already see the look on his face. 
Dynavector 20 Xl , Benz Micro Ace SL or Denon
Dear Raul, Am I understanding you correctly? Don't buy a HOMC? Any HOMC? I have an ARC PH1 phono pre with 48db gain. What cartridge would you recommend to upgrade from a Grado Z+?Thanks,George 
Hum from Grado on LP12.. Better carts to consider?
Thanks Atmasphere. I'm pretty sure there is a ground wire going from the arm base to the bearing sub-chassis. The motor is attached directly to the top stainless steel suspension plate. Is there a missing connection between the top plate and sub-c... 
Hum from Grado on LP12.. Better carts to consider?
After doing much research on Audiogon and the web in general, I am beginning to realize the problem is a ground loop hum. I have a rooftop FM antenna that is grounded to a single rebar spike. This apparently is not a good setup - too much resistan... 
PSE Studio 4 amplifier - any good?
I am currently using the Studio IV and still have the Studio V's which I bought several years ago. The monoblock Studio V's have a bit more 'heft' and bass as you would expect, but the IV has, perhaps, a bit more focus, though I haven't done a lot... 
Home theatre power amp questions
Dear Ajkm and Mwwolf: regarding PSE repairs, Dean Klinefelter is back doing repairs and upgrades. He upgraded my Studio V's with a zero (or near-zero feedback) mod. He was 'under the radar' and had my amps for a while, but they made it back and so... 
Hum from Grado on LP12.. Better carts to consider?
Thanks Sean. I do have the Lingo. I've only had two cartridges on this 'table (both Grado), so maybe it's time to live dangerously and try something new ;-) 
Who needs a MM cartridge type when we have MC?
Thanks again, Lew! 
Who needs a MM cartridge type when we have MC?
Lewm et al., ...sorry to backtrack by a couple of weeks... another basic question: I'm leaning towards an Ortofon M20FL. Do the Otofons have better 'shielding' than the recent Grados (Z+). I have a terrible RF problem where I live.George 
Stand out phono stages
Well-said Ed!George 
Hum from Grado on LP12.. Better carts to consider?
Thanks Coxhaus and Metralla. I did some research on hum problems and tried one suggestion with some success. That was to move the LP12 away from other components, especially their transformers. I realized the turntable motor was about 6-8" away fr...
