Record cleaning fluids
Record archivists use lab grade detergents Tergitol 15 s9 and 15 s3. One attacks water soluble dirt and the other attacks oil based non soluble elements. Mix with DI water. Look for it at Laboratory Technical supply houses. I bought two pints year... 
What of cost goes into manufacturing cartridges?
The sole determinant of sales price is value in the market place. Cost of production etc. only determines if you will make or lose money.Remember Pet Rocks? 
Pre Pro advice. NAD T 187 or??
I recently went through a similar process and wound up with a NAD T185 which is the previous version of the T187 to replace my NAD M15. I am quite happy with the change.The main advantage of the NAD for me was its ability to do stellar two channel... 
VPI 300 RPM vs 600 RPM Better?
I strongly suspect that the amount of motor vibration varies quite a bit based on the position of the magnets in the motor which I understand is not very precise.Small changes in the phase of the motor drive makes quite a bit of difference in how ... 
VPI 300 RPM vs 600 RPM Better?
Silly me, I thought the 600 rpm motor was the upgrade??? 
SDS speed control
If the bars move counter clockwise the platter is slow, increase the frequency of the sds to correct. If the movement is clockwise then the platter is fast so reduce the frequency to correct.If the rate of rotation of the bars does not change when...

Chris, I can't get the correct tracking force with only two small weights.

Chris,The cartridge that I use has medium / low compliance (15x10-6) or thereabouts.I am using three small or one large weight and it is in the area of 5 on the beam.I did notice a little leaner sound with the double leaf spring but found a loss i...

Well I finally got around to trying the dual leaf I beam. I went back to the single leaf as I liked the bass better. 
2 channel priority in HT Processor...who's is best
I suspect the NAD T175HD is quite a bit better and at that price you could go with a M15 and come out money ahead. It seems that the NAD stuff does not get much popular interest but those who have had the opportunity to compare them always choose ... 
Which surround algorithm is better?
I get a very nice sound stage from two channels and vinyl front end so that is how I listen to music. For movies I sometimes use synthesized multichannel. I think I like the DTS synth better than the Dolby on my prepro (T175HD). I don't think the ... 
NAD T973
Yes the T973 sounds much better than a boat anchor.Weight in audio components is generally associated with more solid construction and beefy transformers.John are you enjoying your new found amp?

I have not thought much about the actual mechanics and physics of turntables and arms but some of what I read does not make much sense to me. Perhaps someone can help me understand better.Folks talk about "draining" energy to the earth or some oth...

An interesting set of articles on the ET2 with a little discussion of resonance in tone arms.http://www.stereophile.com/content/eminent-technology-two-tonearm 
Eminent Technology ET-2 Tonearm Owners
Its a fairly long description in the manual but basically involves putting the second arm / cartridge on top of the first while playing a track and "listening" to it to hear resonances in the first arm.It also includes a discussion of how material...
