Is this why my analog rig isn't so hot?
Raul said "I have more than 35 years in testing analog rig and, beyond what Ken told us, the 70% to 80% of the quality of the sound reproduction comes from the tonearm/cartridge combo"...I would have to side with Ken on his interpretation of this ... 
Home brew cleaning solution
I agree that reduced surface tension is important. It should be the goal of ANY type of cleaning agent to penetrate below the surface IF the design of that product is meant to do "deep cleaning" rather than just be a "surface rinse". After all, if... 
Why do only US makers focus on time coherency?
Dawgbyte: From what i saw of Mitch's crossover design from his speakers, Hales are not time / phase coherent. There was an 18 dB / octave crossover in there somewhere if i remember correctly. Sean> 
Why do only US makers focus on time coherency?
Dawgbyte: Thanks for the info on that thread. I'll check it out when i get done posting here. The Ohm F Walsh designs were phase and time coherent, but they can achieve this coherency only at one specific listening height. This height will vary wi... 
Douglas Self on Negative feedback and distortion
Hammy & Marakanetz: I'm somewhere between the two of you. That is, i believe that you CAN hear specs, if the tests are performed in the proper manner and ALL the spec's are taken into consideration and properly interpreted. Having said that, P... 
How do YOU find the hole?
I was able to find the info that i needed on one arm, but not on the other ( so far ). Since it is an OEM Pioneer arm off of a vintage table, i don't know if i'll ever be able to find it. I do appreciate the responses and suggestions though. Sean> 
I'd like to buy a cd recorder . Please help.
Lngbruno: That's encouraging to hear that the TDK held up that well. I have a different model than what you do though as i think that mine is older than the one you mentioned. The model that i have is a DA-3826, which seems to work fine although i... 
X250 Isolation?
Thanks for the response. I appreciate your explaining your process too.. Sean> 
Tube power amp - keep on continually?
Aroc's comparison between tubes heating down and an engine heating down makes for a pretty good anology. Both have built in design tolerances, both require specific clearances / spacing for optimum operation, both are made up of a complex sum of p... 
Ham Radio Interference from next door neighboor
Topvideo, i was only joking but i appreciate the offer. I want to stick somewhere reasonably close to where i am now. I couldn't afford to move all of my audio gear that far : ) Sean> 
Ham Radio Interference from next door neighboor
Glad to hear it. Since that guy moved out, and i'm looking for a house, mind telling me where you're located??? Take my word for it, that guy had a "little" transmitter compared to what i've got : ) Sean> 
Tube equipment use in high altitude?
Gs: The "tubed" ICBM's don't sound quite as "shrill" sounding as they whistle by you... : ) Sean> 
Why do only US makers focus on time coherency?
Dawgbyte: What thread appr 1 week ago was discussing the Walsh driver? I somehow missed that one. Sean> 
Douglas Self on Negative feedback and distortion
I think that what Audioengr was getting at is that there are loop-holes to every generalization. That is, something can deliver flat response over a wide bandwidth at a given amplitude on a steady-state basis, but that doesn't mean that it will re... 
Douglas Self on Negative feedback and distortion
You're asking the right questions. I haven't read his books but i've seen enough quotes from them and read enough on his website to know that he and i don't see eye to eye on too many subjects.I will say that to achieve ultra-wide bandwidth with e...
