I would appreciate any thoughts/knowledge that could be shared here re: the following statement:

"...then adjust the VTA of your tonearm to 200 gram vinyl thickness not 120. If your tonearm doesn't have a VTA adjustment then you never gonna know how good this recording is. If your tonearm doesn't have a VTA adjustment then stick with 120 gram vinyl because your tonearm is set for that." ( http://store.acousticsounds.com/d/34989/Yes-Fragile-180_Gram_Vinyl_Record - see the reviews)

I recently purchased a... you can probably guess... a Pro-ject Debut Carbon. As far as i can tell, it does not have a VTA adjustment - am i correct in this assessment?

So in essence my question is "can i play 180 & 200 gram vinyl at all / worth it / with loss of fidelity or what on my Pro-ject Debut Carbon?"

I found some interesting information on VTA, but an overload of information... I'll share it here for anyone that might not have any answers for me but wants to know more about VTA:

http://www.turntablebasics.com/advice.html (basic)
http://www.tnt-audio.com/sorgenti/vta_e.html (advanced - this kind of sort of maybe answers my first question... or maybe not)

Thanks in advance,

I have had some really bad 180/200gm records. It's really the quality of the recording and the pressing that will give you great sound. Roy Gandy at Rega feels that VTA is of very little significance. To be quite honest I've never adjusted the VTA according to weight of the album. If you want great sound make sure your speed is accurate, and the cart is a proper match for your tonearm.smile.gif

The THICKNESS of the record is what changes the VTA.

Some people make the mistake of setting the tracking force too light.

More records are damaged, IMO, by the mistracking caused by setting the tracking force TOO LIGHT than by any other thing.

When in doubt, always use a little more tracking force than you have if you hear distortion. You would have to at least double the tracking force to damage the record, but too light is a real problem.

I set up my Scout with a 120 gram record because that's mostly what I play on it. Some reset VTA for every weight record but that's just too fiddly for me. I also agree that too little VTF is worse than too much. A correctly adjusted azimuth is very important for balanced channel levels.

Thanks for the input.... i'm going with not worrying about it and playing / buying what i want, whatever the weight of the vinyl.

Excellent Idea !!!
Set it up for the record weight you play the most and quit worrying about it. Just spin 'em and enjoy your music. If you want perfect VTA for each record you'll spend all of your time fiddling instead of listening. When you change VTA it also changes overhang and VTF along with it, and it does the same thing when you change thicknesses of records. It's a damned if you do and damned if you don't situation. As you can see, there's more to it than changing tonearm height (VTA) for every record. IMHO it's better to set up with a medium weight record and leave it be. There is an audible difference in playback with different weights but it's slight and a lot of hassle to adjust for it. Yes, you can play 180 and 200 gram LP's with excellent results but as Class A previously posted there are some really crappy, noisy, expensive 180 and 200 gram reissues out there that don't come close to nice, used originals. I've got a highly rated Speakers Corner reissue of the Alan Parsons Project's "Eye in the Sky" that sounds terrible vs my original I bought back in the eighties. The Speakers Corner version has so much noise in the grooves it's unlistenable. The thing sounds like a popcorn machine and cost $35 bucks less shipping. The original, while not having quite the fidelity of the Speakers Corner, is quiet as a church and it's over thirty years old. Go figure.

Thanks Sam.

However, in my Pro-ject Debut Carbon manual i only see three adjustments mentioned:
Cartridge downforce adjustment
Anti-skating force adjustment
Adjusting the azimuth

I don't think any of those is synonomous wtih Tonearm Height / VTA.

My conclusion is that it isnt there; anyone disagree with this conclusion? This was my other original question, thanks for reminding me.

I did some research and, unfortunately, you're correct. VTA can't be adjusted on your table, it's preset for the cart that came with it. Bummer!

oh well (thanks for doing the research)... i'll just pretend i set it and its permanent = )

it seems to be a pretty well liked turntable, and i have no complaints, so they must have set/fixed the VTA well enough.... good enough for me.

thanks again
