Is SUT needed for a low output cartridge with a Gryphon Pandora & Legato phono module?
I recently upgraded my cartridge from a high output Sumiko Blue Point Special EVO III to a low output Dynavector DV-20X2L cartridge. I changed the impedance settings on the Gryphon Legato phono module from 47k to 80 ohms and the results are very good. The Dynavector cartridge is noticeably better than the Sumiko. . Some have suggested that a step-up transformer may produce even better SQ results.
I'm hoping that someone with a Gryphon Pandora preamp with the Legato phono module may have already experienced using a low output MC cartridge and can chime in whether a step-up transformer improves the SQ.
Waste of time in my view, SUT's are so variable both in quality and matching you'll be opening a pandoras box (couldn't resist). The Gryphon phonos are very good, no need to look elsewhere. I used one with an ultra low output Ikeda ( 0.15mc ) - dead quiet and very good - better than SUT's I tried at the time. |
Thanks @dover and @jasonbourne52 for your replies. According to the Gryphon Legato user manual, below are the specs including the available gain that @jasonbourne52 asked about. Technical Specifications (Balanced operation) Signal to Noise ratio: MM 86 dB Unweighted Ref. 10 mV MM 90 dB A weighted Ref. 10 mV MC 68 dB Unweighted Ref. 0.5 mV MC 72 dB A weighted Ref. 0.5 mV Gain MC: 68 dB Gain MM: 38 dB RIAA tracking: +/- 0.1 dB 20 - 20 kHz THD: 0.01% Output impedance: 50 Ohms Input overload margin: MC 30 mV pp MM 700 mV pp RIAA out: voltage sving 60 V pp
