New phono stage from SOTA
SOTA will soon be releasing a new phono stage that they debuted at CAF. I’ve gotten to know the designer who lives about 5 miles away and am currently using one of his prototypes that's been installed for about 9 months. My other equipment - Miyjami Shilabe cartridge, VPI TNT turntable w/ ET 2.5 arm, Muse preamp, Son of Ampzilla MK II amp, Audio Artistry Vivaldi speakers, HSU subwoofers. I've owned three other dedicated other phono stages over the last 30 years, one retailing for over $3,000, and this unit far surpasses those. I have no financial interest, just thrilled with this piece and wanted to pass this along. Looking forward to what the reviewers have to say. https://sotaturntables.com/company-news/sota-pyxi-phonostage/
Never mind, I read the article. Flat RIAA, low noise, no added colorations. How does the designer determine this last part? I went to the SOTA site and it seems the device is available but the shopping cart is throwing an error. Things don’t appear to be working at the moment. Please try again later. |
The Sota web site is being updated to allow for EU (and UK) purchases of the Pyxi. How did I determine "no added colorations?’. Well, I didn’t that was SoTa’s conclusion. I just followed a philosophy which amounts to, 1. Flat RIAA- variations over the audio band below the subjective threshold. 2.Extremely high power supply rejection, and extremely low power supply/ground interaction between stages. 3. Distortion which is below the acoustic threshold (-110dB FS) measured whatever way you choose to do it. There are other aspects, but you get the gist, hence the designed to be explicitly neutral. Finally in subjective testing. It actually sounds neutral, with a very high degree of clarity.

@wynpalmer4 Thank you for the clarification. Would the unit benefit from a larger 14VAC supply? |
The larger unit does not use the 14v wall wart. It, presently, uses a very different supply. The Pyxi WILL NOT BENEFIT FROM A CHANGE IN THE WALL WART!!! The 240v version uses a 15v wall wart due to availability issues. Using a 15v wall wart in the US version could compromise the reliabilty. Even using a different 14v unit could do the same. The filtering/regulation circuitry was carefully designed for the 14v wall wart that was used. |
