    Holo Audio May DAC Speculation

    Maybe 5-7 seconds. I don’t exactly remember because I don’t switch sources around. It only takes that time when you switch sources.

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    Based in the follow owing graph you could make a faraday cage or box out of 0.067” thickness or greater 410 steel to shield the primary 60hz frequency. Also, adding distance between you and the source will help mitigate. https://en.m.wikipedia.org/wiki/Skin_effect (The red line represents 50hz)

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    The 91905-69 has the same 0.0005pf capacitance as the -31 and -32 transformers and the exterior construction is the same as well. The difference is it can accept 100, 120, 200, 220, or 240v input and outputs 120 or 240v. The only one I’ve seen is the one I have and unfortunately I don’t have any...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    If the power draw tops out at 700W then an 2KVA IT should be fine if the UPS is t replenish itself. If it needs to replenish itself then you would have take that into consideration as well.

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    @mkaza I’d think the best sound quality would come from the wall/IT/component combination but since you already have the UPS it won’t hurt to give it a shot. I had a Surgex SA1810 prior to my Topaz/MGE units. They are good but don’t offer the same level of performance as my ITs. In the purely...

    FS: MGE T100R-1800 (newer version of Topaz/MGE Isolation Transformers)

    I am selling three MGE T100R-1800 isolation transformers. These are newer versions of the much sought after MGE/Topaz 91XXX—3X isolation transformers (T1 series). I wanted a closer look at one of curiosity but it was a package deal for 3 so here I am. These only accept 60hz or else I’d take...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    Based on the photos (since I closed the case up) it appears the T100R core can be wired for balanced power if so desired. My guess is this allowed the manufacturer to use the same core for both the T100R and T100H models that corresponded to each other. I plan on testing this out and wiring one...

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    I just re-terminated the plug. I’d rate the magnetostriction transformer noise as on par with the large unbalanced -31 and -32 transformers. Makes sense considering the multitude of vents means the core isn’t well sealed from the air outside the enclosure.

    Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power

    My power cable quest stopped at my naked 8 awg magnet wire. I haven’t had much time due to work recently to construction a starquad version of the 8 awg magnet wire with. Plus I need to find a new source for the wire. The place that I bought my current stock from ran out. That being said, I am...
