New phono stage from SOTA
One other thing, I am well aware of the rather, how shall we say it, questionable (or at least questioned) results concerning the ultrasonic sensitivities of human hearing. In any case what makes you so certain that those very sensitivities were ...

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...

Oh. The Sota Acrux will be a bigger box with more functions (knobs and buttons) and even better specs and capabilities- all for 8x the price.

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 o...

The Pyxi architecture is, as far as I can tell, unique, or at least highly unusual. The design is configured to be explicitly neutral. Your preferences are, frankly, inconsequential without some non-empirical basis to support them. Despite the l... 
Pyxi phono stages, two systems.
The Pyxi did have mechanical issues that delayed shipping. Those problems have been resolved and the unit is available, although the first build was quickly sold out. You can order directly from SoTA or from select  dealers.  
SEEKING AN AMPLIFIER THAT MATES WELL WITH MARTIN LOGAN 11 A IMPRESSIONS
I have a pair of ESL11As, which replaced a pair of Montis. I sit about the same distance away as you do, and the speakers are 9’ apart. I have a somewhat larger room, and the back of the speaker bass box is c. 2’ away from the front wall and the s... 
Hovland HP-100 Preamp - Anybody Have Bob Hovland's Contact Info? Thx! :)
I have an HP-100. I rarely use it as I find it excessively colored for my taste, although I enjoyed it for some time. I digitized the output from the line stage and from the "tape" output and they sounded very different, so I spent some time trac...

@rauliruegas  Here is the recognized US definition of freelancer: A freelancer is an independent contractor who earns wages on a per-job or per-task basis, typically for short-term work. Benefits of freelancing include the freedom to work from h...

Dear @tablejockey. The claim was not mine. There are certainly many compromises that need to be made in a commercial design required to sell for $300. However, the measured performance is remarkably good for a unit of this price- equivalent to or...

Several years? I was with ADI- designing a wide variety of ICs for almost forty years and was most fortunate to become an ADI Fellow and Senior Fellow. I am not a free-lance engineer. I retired from ADI a few years ago and I design audio (and oth... 
Cartridge Loading.....Part II
The virtual ground doesn't care what the origin is of the impedance in series with the voltage source. An ideal virtual ground simply means that all of the current that enters a node is conveyed somewhere else with a zero change in the voltage at ... 
Cartridge Loading.....Part II
A copy of a post I placed a short time ago...   I'm in the process of having a phono preamp made manufacturable by a well known audio company. The first thing they insisted upon was that the design would be implemented in SMD- purely for manufac... 
Cartridge Loading.....Part II
The distinction between virtual and actual ground is a subtle one. When an opamp inverting input is used, the virtual ground is extremely similar to a real ground as the action of negative feedback makes it so. The difference is in the error term... 
Voltage mode vs current mode phono stages
I'm in the process of having a phono preamp made manufacturable by a well known audio company. The first thing they insisted upon was that the design would be implemented in SMD- purely for manufacturing purposes. This had it's own unique set of d...
