Albert Porters after market panzerholz plinths

Mr Weiss lovely work you do. Your choosen plinth material Pennsyvinia soft slate did you select by scienctific methods or guessing this material maybe be good and simply trying it.

Jonathan,

i'll do my best to answer your question.

Albert does not do the 'nude' SP-10 Mk3 plinth. his Mk3 plinth design keeps the case-work on the Mk3. Steve Dobbins Mk3 plinth, which i own one of, does at least remove the top case-work. however; i do not know myself whether he removes anything else from the Mk3 before installing it in the plinth. my impression from my conversations with him is that the motor is secured directly to the plinth; but exactly what that might mean relative to your question i'm not 100% sure of.

A question about comparisons, based on the Walker-Technics comments posted here.

Many experienced hobbyists agree about the importance of component matching - speaker with room, amp with speaker, arm with cartridge. Raul was pretty specific when he suggested the importance of arm, headshell, and even platter mat for cartridge performance.

Why then would anyone argue that the only fair comparison of the Walker versus Albert's Technics should be made using the same or identical arms and cartridges? Who is to say the optimum arm for Albert's Technics would be the same as that used on the Walker? And even if the same (or identical) cartridge(s) was/were used in the comparison, what is the assurance it/they offer optimal performance when different arms are used.

This may not seem scientific but I believe music is an emotional experience. Therefore applying science-based tests may not always be most appropriate. For me a better test would be to optimize the Walker and it's arm with the best matching cartridge (obviously choices will vary but since the evaluation will be made on an individual basis I consider this OK). Then do the same with Albert's Technics, this time matching arm and cartridge. Then make the sonic comparison with EACH table optimized.

Your choices in optimizing each table may be different than mine and our respective conclusions may or may not agree. But each of us would have based our ratings on the best we felt each table could perform.

I trust this in not beating an old subject to death but in all my years in this hobby I've simply observed too many varying opinions about what is good and what is not so good to believe that rigorous "scientific" testing procedures (eliminate the variables) present any truth.

Pryso,

my guess, knowing the likelyhood that Albert tried quite a few of the pretender/contender cartridges while he owned the Walker, is that Albert had a pretty good idea of what cartridges worked the best on the Walker. and in any case; the Walker does not allow for an alternate arm, so you are stuck with comparing the Walker with it's fine linear tracking arm.

so Albert would have been in as good a position as anyone to make the comparison with the cartridges he knew at that time. he had way more experience with cartridges on the Walker than the Technics.

i have a Rockport Sirius III and sitting next to it is a Dobbins Technics SP-10 Mk3 with a Reed and Talea arm. i have multiple cartridges which have been switched back and forth. i have my opinions about this and that which is as close to 'a truth' as you are likely to have.

i respect Albert's perspective.

Mike, I may not have made my point clearly. I too respect Albert's experience and perspective. So based on that I can accept that he believes his custom Technics to be more satisfying (better?) than his (at the time) Walker.

My intended point was to challenge those who discredited his conclusion because of component variations - the arms in that case. Comparing different turntables by utilizing the same platform, arm, wire, and cartridge may not necessarily be a level playing field in my opinion.
