SME 20/2 sound problem. Remedy suggestions needed


Dear Readers! I bought SME 20/2 w/V tonearm as an upgrade from my Roksan Xerxes w/SME IV tonearm. I use Denon DL 103R cart, a very good phonostage just in league with Manley Steelhead, amplified in biamping by Primare Integra on high/midrange and Krell KAV250a on bass, Danish Physics DP.02 speakers. Xerxes palyer with very airy big warm soundstage, the vibration bound turntable design (similar in construction to LP12) being compensated by rigidly controlling Krell produced a rhytmical, colourful sound. Lots of so called coloration transformed into big big lively music. Now replacing it with SME 20/2/V arm all life got immediately lost - sound is dry, flat and monochromatic . Could it be that Denon DL 103R does not live up any near to the SME high end purism, or would You rather say that theres no synergy between a very uncoluring and rigid SME deck and Krell which is known as most monochromatic synthetic and sterile sounding amp? Is it possible that given same system and cartridge the difference between Roksan w/ SME IV and SME 20/2 w/V arm could be so startlingly negative towards the SME deck? I read somewhere that SME decks play flat on rock - I listen mostly to rock/metal - but such a vast devastating difference? colours vs no colours, life vs lack of vitality, music vs. synthetic flat sound? Please help with your knowledge, I'd highly appreciate suggestions. thank You!

I totally agree with Pgtaylor. The SME turntables are far more neutral and of higher resolution than the typical mid-priced Brit belt drives from Rega and Roksan. While I've never heard any of the REALLY expensive (> $100K) turntables, the SME 20 and 30 series are the best I've personally heard, particularly in the ability to convey the emotional power of the music. At first Concerning the DL-103, the SME IV has the same effective mass as the SME V, so it must be the 20/2's ability to drain more spurious vibration out of the turning of the record. In other words, the Roksan table's colorations were compensating for a bad cartridge/arm match. The DL-103 needs about an 18g arm, and the SME IV and V have an effective mass of 10g. Have you messed with VTF and VTA on the SME to listen for the effects?

I was listening to a Roksan Radius a month ago and found it to be highly colored. The midrange was recessed, which made the bass and the ambient details sound bigger than they really are at the expense of the voice or instrument carrying the tune. Switching to a more linear turntable may be revealing a less than optimum arm/cartridge match.
I have heard Lyra cartridges on the SMEs that sounded fantastic.

As for the DL-103, it famously has a short, stiff cantilever and wants an effective mass around 18 g. With arms with detachable headshells, this is easily remedied with a heavier headshell. Not so easy with a fixed headshell, but could be done with a headshell weight.
