SP10 Mk II vs Mk III


A couple of guys here were planning to do listening comparisons of the Technics SP10 Mk II vs the Mk III, in their own homes and systems. Has anyone actually completed such a comparison? I am wondering whether the "upgrade" to the Mk III is actually worth it in terms of audible differences between the two tables. Possibly mounting either table in a well done wooden or slate plinth mitigates any sonic differences that would otherwise be heard. I am thinking of Albert Porter and Mike Lavigne in particular, who were going to do the comparison. Thanks for any response.

T-bone,

The MkIII was modified as well by Steve Dobbins. The plinths for each table used different materials to deal with the motor noise created by each table. Steve Dobbins described to me what he did with each of the three tables but I don't remember them all. Maybe Steve D. could weigh in here or maybe you could contact him directly for the information. The work he did on all of the tables was substantial.

Johnp,

great report on the shootout between the Dobbins tt's.

as i own(d) all three of those exact tt's (i sold the Mk2 last year and still have the Mk3 and 301) your report has interest to me.

first a comment; i never percieved my Mk2 with Schroeder Ref SQ arm as 'dry'. audiophile terms are not exact things and one man's dry is another man's 'detailed and transparent'....in any case, the Dobbins Technics SP-10 Mk2 was involving and natural sounding to me. OTOH i've not had a Strain Guage cartridge in my system.

a question; did the Dobbins Garrard 301 use the Loricraft UPS 301 AR power supply? i've only heard mine thru my Loricraft so i'm just wondering about how the presence or not of it might affect things.
one more thing......thanks for the report on the Dobbins 301 platter. Steve is supposed to be visiting me in a few weeks and he'll be bringing the 301 platter which i'm planning on purchasing.
Hi Lew,

"But I must confess, there is so much information in your post that one essential element eludes me; were the MkII and the Mk III BOTH mounted in Steve Dobbins' plinths?"

Yes, both were mounted in Steve Dobbins' plinths. However, all three plinths used different materials and construction. Each was designed to reduce noise transfer from the particular motor of each to the armboard and platter of each. Steve tried many combinations.

"Also, what platter mats did you use on the Technics tables?"

The MkIII had a SAEC SS-300 with a sorbathane "like" material on top of it. The MKII had the orignal rubber mat. Since getting my MkIII, I have tried two different mat combinations. First I compared the original rubber mat to a Saec SS-300 with a Herbie's Way Excellent Mat on top of the Saec. The Saec & Herbie combination sounded muffled and dull in comparison to the rubber mat. Next, I compared the rubber mat to the Saec mat alone. I couldn't hear any difference between these two mats. For each of these comparisons, I adjusted the VTA on my arm to get the best sound for each combination.

The 301's I heard previous to listening to Steve's 301 were uninvolving for me, no "juice". The plinths were different so maybe that would account for what I heard, I don't know for sure.
I don't remember all the modifications that Steve did to these three tables, but I know what I heard. In this situation, the MkIII was much better than the MkII but maybe in a situation with different plinths with different modificaitons the outcome may be different. I can only give you the conditions for this comparison and my opinion, for what it's worth, given these conditions.

Best,

John
Hi Mike,

I not sure what power supply Steve used during the shootout.

Best,

John
