Last weekend the Steve Dobbins plinth'd SP-10 Mk3 finally arrived, in all it's retro glory. Friday night i drove the 1000 mile round trip to Boise from Seattle to pick up the Mk3 with the new plinth, another Triplaner, a new 12" arm, the 'Reed L', 2 brand new Allnic Verity Z cartridges, a Lyra Olympos, and.....Steve and his friend Keri.

a great 6 hour drive filled with talk about analog, more analog, and cars.....boys and their toys.

Steve and i had talked frequently about which arm to use on the Mk3. we had considered another Triplaner, the SME 312s, the Schroeder Ref SQ, and some others. We had somewhat settled on another Triplaner in addition to the one i already had on the Garrard.

we arrived at my home around noon Saturday. my friends Jonathan and Dale (from Portland) met us at the house at noon and stayed into mid-day Sunday.

Steve set up the 130 pound SP-10 Mk3 on the GPA Monaco stand between the Rockport and Garrard. Steve installed both the Triplaner and Reed L arms on the Mk3; both with the identical new Verity Z cartridges. my now 35+ hour Verity Z cartridge was still installed on the Garrard/Triplaner.

First we compared the 2 arms; and to my surprise the Reed sorta kicked the Triplaners butt. more detailed, more energetic, and more vivid, more impactful bass.....we had them both plugged into the Allnic H3000 phono stage so were able to quickly A/B. i had very much liked the Allnic Verity Z/Triplaner combo on the Garrard and so was surprised at how much better the Reed sounded.

i'm no expert on arm design; the Reed L is a 12" long gimbaled bearing design with a wood arm wand. the fit, finish and assembly quality appear to be first rate. it's retail will be under $4k.....i think a great value. i will be keeping the Reed.

first impressions of the Mk3 were wonderful. this is a great tt. very very low noise, lots of detail, amazing energy, PRAT to die for. music literally jumps from the grooves. musical lines are well delinated. big soundstage. i was likeing everything i was hearing.

i love the look of Steve's plinth design in person. it has a presence and form which looks right. to install the SP-10 Mk3 motor and platter into the plinth Steve removes the 70's casework and speed controls; and only the motor and platter are inside the plinth. speed control is then done from the power supply. Steve feels that the performance of the Mk3 is optimized by this design as it eliminates the limitations of the 70's sheet metal casework in terms of controlling the huge amount of torque of the Mk3 motor. in any case; what i hear from this tt only validates Steve's approach.

in addition to the work on the plinth; Steve also does a few things to the power supply; including new caps.



after the arm comparison, we mounted one of the new Verity Z's on the Rockport so we could compare the Rockport to the Mk3. we spent the rest of Saturday night into the wee hours doing this comparison. and now, a week later, i am still forming conclusions. there were various impressions around the room as to how the tt's compared. i will only speak for myself.

provisionally; the Steve Dobbins plinthed, Reed armed, Mk3 is in the ballpark of the Rockport Sirius III in performance......when using these identical Verity Z cartridges. the Mk3 slightly betters the Rockport in terms of energy and bass impact. it has a slightly higher sense of vividness. the Rockport has more texture and detail. the Rockport is more refined and nuanced. in terms of nosie floor; you hear deeply into the music with the Mk3.....but more so with the Rockport.

what the Rockport does well is unique to the Rockport.....and it comminicates the music on a unique level.

other tt's do some of what the Mk3 does. but it is also on a special level for the ability to pull you in. i'm not completely ready to yet make any definative comparative statement; only that i continue to investigate these 2 great tt's.....and that i am completely happy with Steve's work.

sometimes when we descibe wonderful gear we forget it's about the music. i want to make the point that all through this wonderful exhausting weekend it was the great music we played which was the main event. we were all having trouble focusing on objective gear issues with so much great music. i wish i would have written down all the great cuts we played.

it's Mother's Day so i must go enjoy the day with my family. later i will descibe more of the weekend.....we mounted the Lyra Olympos on both tt's on Sunday (the Olympos is still here a week later). Monday am i dropped Steve and Keri at the airport. it took me 3 or 4 days to recover from the drive and 2 days of intense listening. as intense an audiophile time as i've ever spent.

Helluva nice looking set of equipment! :-)

I imagine it sounds as good as it looks.

How does the sp10 mk3 compare to the Garrard? I have had a Garrard and sp10 mk 2 in the same system and liked the Garrard better. The sp10 lacked weight in the mid band, you can say it was neutral and the Garrard was colored but it was something I liked compared to the sp10.

It would be interesting to hear your thoughts on the sp10 compared to the Garrard.

Great stuff!!

David

Great write up Mike!

I sense that everyone enjoyed Steve's plinth and the SP-10 MK3. I hope you recover soon!

What I would like to hear later is how you feel the SP-10 MKII and SP-10 MK III compared and contrasted.

I realize you never had the Reed arm on the MKII but these gut level comparisons are interesting in an arm chair quarterbacking fashion.

Thanks for posting.

Those three tables sure look handsome in your room. I bet each of them communicates music with vitality and passion.

What a great hobby when you can play with cool toys while enjoying extraordinary music and great friends. I bet they had as much fun as you did!

Cheers!

A Technics SL1200 on a custom plinth and the GPA Monaco stand, with the same tonearm, cartridge, etc... I'm sure you would hear a difference, but I'd be interested in knowing exactly how much of a difference.

"Last weekend the Steve Dobbins plinth'd SP-10 Mk3 finally arrived, in all it's retro glory"

Doesn't look all that "retro" to me. It looks like an elegant example of form follows function while wearing a tux and black bow-tie. A gorgeous update. Those cantilevered armboards do make it easy to adjust overhang, do they not!

It looks like a lot of fun.

Man, that is just gorgeous! Congratulations on what looks like a perfectly conceived and executed project. I wish I could hear it . . .

I am about to embark on an SP10 project myself and would like to know more about the plinth construction. Does Steve have a web site (couldn't find one in a quick search). If not can someone put me in touch with him please?

I am especially intrigued by the removal of the top plate, I did not know that was possible. I can see how it could make a lot of sense in a massive plinth like yours. Anyone have advice on this aspect?

Check out the DIY audio forum thread below. This thread is all about designing and building a new controller that will allow the motor only to be mounted on the plinth, which should have a large impact on the quality of playback.
The controller will be mounted in its own seperate enclosure. Also, a new power supply design will be employed.
The new electronics will ensure easier and more accessible parts and hopefully more control and performance.

Steve Dobbins can be contacted by e-mail; vetterone@msn.com

the Plinth is built with layers of man-made slate and duraluminim. he makes other plinths with various materials in engineered constrained layers. he experiments to find what plinth design approach best compliments the turntable.

in the bottom picture you can see my Garrard 301 to the right; Steve built the plinth for that using layers of 6 different materials.

Tubes,

it was a great time and memorable for sure.

the Mk2-Mk3 comparison is tough with different arms and cartridges (and a 4 month gap). if i were to make my best 'guess' i would say that the general character is similar; but the Mk3 is on a whole different level of energy and life. it's bigger sounding as well as having better detail retrival and musical envolvement.

would all Mk3's sound like this one? here i must defer to Steve who thinks that the removal of the casework increases the energy level and reduces the noise floor significantly. what i hear causes me to agree wholeheartedly. Steve felt that the ideas in this particular plinth were beyond any other plinth he had yet done.

i'm a happy camper....

You've done it. The first new DIY SP-10 MKIII/Dobbins two arm table. Just like what I was dreaming about - wow. I liked your written first impressions and can't wait to read a full review. If you can get somebody to bring over a TW Acoustic AC-3 running your arms. Reading your write -up on your three tables and adding a TW AC-3 would be very useful for those of us that are looking for the next step up in TTs upgrades. I'd even subscribe!

well...er...um. ok.

if someone wants to bring their AC-3 over i suppose i'm game. but i'm not removing my arms (tone-arms that is) since Mr. Dobbins has set them up and i'm not in his 'set-up' league now or won't likely be anytime soon.

i've heard the AC-3 and it's a very good sounding tt....deserving of it's reputation. i would not even guess how it might compare to the Dobbins SP-10 Mk3. a very reluctant, hesitant guess might be that the belt-direct drive difference would be telling.

Love your' setup. I was wondering if you wouldn't mind talking a bit about how the turntables compare to the MPD-5. I am thinking of purchasing the MPD-5 or the MPS-5 and would love to know your' thoughts.
Thanks,

Don

mikel.
great read. I like what has been done to the SP10. I too have rebuilt mine. with extensive work on the motor housing, new plinth and new platter.(didn't like the sound of the original)
Plinth is triangular laminate of acrylic and lead, sand filled feet inserts. 70kg. Platter is laminate acrylic and lead with dural magnet housing.10kg
Motor is laminate of dural and original aluminium structure with lead loading.

would like to send you and Steve photos. can this be arranged?

What's up Doc? (Sorry, couldn't resist!) :-)

Why not post the photos directly into this thread? I'd be interested in seeing your turntable and I'm sure others would too.

cactuscowboy. Thnaks for the positive view. I still think that it looks great now, 10 years after I built it. Then I am a bit biased since it is the fruit of my loins so to speak. The prime goal of the design was performance, asthetics came as a byproduct of that. There are sound engineering reasons for a non-suspended tt to have three widely spaced feet and a low profile. Its not apparent from the photos but the front two are made from PVC and are adjustable. The rear foot is aluminium supporting a tungsten carbide ball which contacts the granite slab. This foot is fixed.
