Building high-end 'tables cheap at Home Despot II
Although it's OK to replace a 12AX7 with a 5751, the 5751 is electrically slightly different, mostly in that it has a lower mu and slightly lower plate resistance than a 12AX7. And I am not sure the 5751 is inherently a lower noise tube compared t... 
Our home system: How good it is?
Elinor, Amen to what you wrote above. Home theater and the internet have killed the retail two-channel audio industry and the camaraderie that went with it and are threatening this hobby. I have a couple of 30-year friendships with guys whom I fir...

Robyatt, Thanks.

Your enthusiasm for the Ortofon caused me to try to learn more by Googling it. All I can find is text that refers to their 2M model, which apparently had design input from a person named Per Windfield. I found no reference to an Ortofon cartridge ...

"The ESS AMT4s have those fabulous Heil Air Motion Transformers midrange/high-frequency elements (said to be the best overall driver ever developed)..."Who said that? I remember those drivers quite well. Heard them with a wide variety of ss and tu...

Dear Robyatt, I would be very interested to learn the results of your testing. I am on the same or a very similar path. I quite agree with you re the special qualities of the very weird RS-A1 tonearm. However, no matter what I find in my own expts... 
Belt stretch
Rccc, Assuming you own high quality examples of belt-drive and direct-drive turntables, have you done the experiment of listening to each one with the same tonearm and cartridge? If so, do you hear any differences that could therefore be ascribed ...

Unfortunate metaphor, JW. Having once owned a beautifully restored Porsche 550RS Spyder, I would choose it over Schumacher's race car any time, but I guess I know what you mean, and I do agree with your basic sentiment.Robyatt, I would be interest... 
table turning backwards
Shadorne, That takes the prize for the funniest post I've seen in a long time, and in the process you managed to give good advice: check the capacitor. Also, "reverse the plug" assumes you have a two-prong plug. If so, pull it out of the wall sock... 
How Many Turntables Have You Owned
I did indeed have an ADC XLM at about the time I owned the Transcriptors/Vestigial, but I don't remember that there was any special association between the two. The XLM was just thought to be a great cartridge in those days. I once bought about te... 
How Many Turntables Have You Owned
The Vestigial tonearm has to be the weirdest device I ever owned. It should not have worked well, and I really have no recollection of how it sounded. But I think it inspired the Dynavector 505/507, which certainly is a top level tonearm. The Vest... 
How Many Turntables Have You Owned
Since early 70's: AR with AR tonearm, then Transcriptors Reference with Vestigial tonearm, then Thorens TD125 with Keith Monks tonearm then Alfason tonearm, then Sota Star Sapphire III with Alfason at first and then later the Triplanar, then Notts... 
Atma-Sphere MA-1 amps
This is a very interesting thread. Trcnetmsncom, I looked up the impedance curve of the Avalon Eidelon. It's below 5 ohms (closer most of the time to 3 ohms) between 50Hz and 20kHz, except for a narrow "peak" in the midrange, where it gets up to 7... 
$ 2500 -- Best Way to Spend It Today ?
I've got to agree with Oregon. You can find a mint Lenco L75 or L78 or a Goldring-Lenco for under ~$300. Then ditch the standard tonearm and invest in a Rega or some equivalent, and you'll still have plenty of money left over. What's more, there i... 
dead quiet
BdGregory, Where do you get your AC power for all the gear? Is it coming from more than one wall socket? Is the system AC grounded at more than one socket? If so, the simplest thing to try first is to lift the grounds of all but one component, pre...
