In Reply to: RE: I have the Eagle PSU on my Thorens and had a SDS when I had my Scout. posted by Lakeshore Larry on November 29, 2015 at 05:07:48
I've never used either one, and so far don't feel a need to buy either of 'em. 'Course that could change if I was able to demo in my system.
Have you directly compared the Eagle and SDS in use with your tt and found the SDS did not provide stable speed? If so, with what tt?
Follow Ups:
I own a Phoenix Eagle PSU and RoadRunner and use it with a VPI Scout turntable. I have never owned or used an SDS. I never said the SDS does not provide stable speed, I said the Eagle is more stable.
Phoenix has compared the two and measured the differences in stability:
Since you've never owned/used a SDS and haven't directly compared it with the Eagle, I can only assume you base your statement that the Eagle is "more stable" than the SDS just on what the Phoenix guy claims.
Seems to me that if there's a significant difference between his product and the SDS the way to show it would be to employ each device separately one after another with the same tt and compare/measure the results when the tt is running - not just initial startup.
I think the greatest advantage of the Eagle over the SDS is its ability to be controlled by the RoadRunner tachometer in order to maintain accurate platter speed. To me, that constitutes a substantial advantage. Next to that, the only other major advantage is cost. The Eagle and RoadRunner combination represents a cost savings of $641 compared to the much more expensive SDS. Based on those two advantages alone, I don't understand why anyone would be promoting VPI's SDS over the Phoenix Engineering components. However, to each his own!

I have to agree that the CLEAR advantage of the Eagle over the SDS is the cost and the ability to hook up the roadrunner for constant correct speed management. Do VPI tables run at accurate speeds? Absolutely. Do they drift over time due to belt wear, movement of stand alone motor from platter, bearing wear, etc.? YES. Does the Roadrunner/Eagle combo control all of that? YES. Fantastic product.
that cost difference would sway me -- assuming the Phoenix products work as well with my SAMA as an SDS would.
Both the Phoeinx and the SDS are great products. The $ difference between the two is considerable, but VPI has been in business for 40 plus years, therefore, they will be around to support the SDS for many years to come. The audio business is a real tough business and the survival rate is difficult. Something to consider.
This argument is often used, but how important is it really for a system that costs only $759. The warranty will protect you against manufacturing defects and without any defects, most electronic components usually last a very long time. Therefore, even if the component breaks 10-years from now, it will probably be more cost effective to buy a new one rather than have it repaired.
How many audio components have you had to repair over the years? I have probably spent one hundred thousand dollars on stereo equipment over the years and I've never had to pay to have a component repaired. The very few components I've owned that have failed all failed during their warranty period. Therefore, I don't think your argument holds the slightest bit of weight for something that costs only $759.

The fact is that a lot of money is spent in the repair of audio gear. Some repairs are normal wear and tear, and others are components that failed out of warranty after only a few years of use. I know a lot of DIY'ers who can pull off simple repairs that save them good money. But the repair of a digital speed controller? Nope, that's going back to the manufacturer.
I'm a dealer for both products, and both products are fine. VPI has more years in business than Phoenix has months, but VPI had to start somewhere too. I wish Phoenix much success.
I find these devices interesting. In the case of VPI, their controller works well but does no monitoring of speed.. Phoenix does, but they can't correct an error, they can only compensate after the error.
"Hope is a good thing. Maybe, the best of things. And no good thing ever dies."
Good point. But you also have to consider the age of the SDS, IIRC it's pushing 20 years and the parts used in 20 year old designs have a way of going obsolete.
One of their customers just got bit by this on his PLC controller which might only be 5 years older than the SDS:

Did you look at part 2 of the video?
When I saw the tt near the end I was hoping that he was gonna do the kind of comparison I mentioned. To me - a technical ignoramus, the most interesting and persuasive test would be to actually *hear* a difference between the two products as well as see it on a tach.
Lakeshore Larry....so what?? They say that there is instability while starting, or changing speeds.... By the time one releases the tonearm to play the record, the instability checks itself out. My turntable (VPI Superscout rim drive with SDS is stable to MY ears. It runs when at 33, from 33.2 to 40.1, but varies primarily long term from 33.3 to 33.6.
See above (re part II).
33.3 to 33.6? Or is it a truncated 33.69 (let's call it 33.7, what's .01 between friends)? So your maximum speed error could be 1.1%? If that's not a problem for you, then congratulations and enjoy.
Whenever a manufacturer compares one of their products to a competitor's, they lose all credibility for the test. They can rig the parameters any way that want to skew the results. I suggest that claim is bogus from the start and not even worth considering.
