The Schiit Modi Multibit is your answer. Andrew

With a very brief chat with Paul during a show, I got the impression he was very supportive and encouraging of others. A brilliant reviewer too, the industry will really miss him. Andrew

Great, but it doesn't look like the stylus is replaceable. Andrew

Here’s one. Hermes, just before they changed name to Evri because of the “reputation “ they built. I’d sold an LP12 Cirkus sub chassis on PFM, and packed it in a big padded and bubble wrapped envelope. You know how the Cirkus sub chassis is. Two parts of steel in a reinforced arrangement...

Actually the effect of the GaN psu produced a natural softening of the treble, leading to a heightened ‘hear-through’ dimensionality to the perceived sound. In the humble opinion of my logarithmic hearing. Andrew

I’ve been trying to find a video I saw about a year ago of someone performing a test, showing GaN charger produces a significant reduction in noise over a silicon charger (i.e 10s of dBs). It will also operate at a much higher switching frequency. What I have seen is that GaN FETs produce less...

Some models quote 65W and then state one port is for 30W and another is 35W - which is a bit of a cheat. Andrew

Hang on, I was going to buy another one. At this rate there will be none left 😆 Andrew

I guess you are unfamiliar with the principles of superposition and modulation. If you need an explanation then may I recommend a good book like Circuit Theory by J.K. Fidler. Once you have read that, then read up on communications theory and modulation/demodulation on optical transmission...

Neither does soundwaves over radio. They are both modulated though… Andrew

That’s a bit like “how does sound travel over radio waves?” Andrew

Escape M1 streamer and Accuphase DP450. Also the comparison was conducted previously and separately on my system - picoreplayer (using coax) with an Audio Note 2.1 Signature DAC and Schiit Modi Multibit. Both streamers work off 5V DC. The main takeaway is that if you are using a 5V powered...

Regarding no noise traversing the optical cable - have you considered the modulation of the light source with noise, spurious harmonics and other sources of imperfection? As you point out, ground plane and back EMF are also another consideration. Andrew

“The sound of vacuous beauty” Andrew

Here is a nice engineering link, showing the benefits of Gallium Nitride in the power supply. https://eepower.com/technical-articles/how-gan-fets-have-become-the-technology-of-choice-for-audiophiles/ Andrew
