Note in the above set-ups, that the grounding has been removed from the analogue stages of the setup as it was degrading the sound quality. This became clear during the installation of the Melto2.

One thing that is for sure is that the EtherREGEN and its PSU run hot; very hot. I have ordered some heatsinks and will bond them to a machined brass plate (3 mm for the moment) to improve their cooling. It certainly does. Mine has sported a large finned heatsink on its top surface for a long time.

I completely agree - grounding boxes only work on my digital components, too. I tried and removed analogue grounding some time ago.

Interestingly, it was not apparent on the Uphorik, but the it was obvious on the Melto2 and you could even here the grounding on the Allegri +.

Thanks, Mike, but the cables are not quite as tidy in reality!

Cables have a way of tangling themselves up when you're not looking

Closely allied with socks and quantum theory !

Apparently Erwin Schrödinger only ever wore one sock: once he'd opened the drawer and taken one out, the other could never been found!

Perhaps the other one was superpositioned with the one he was wearing?

Thanks for the listen and coffee earlier, Pete. I'm playing the Ani Difranco and Cowboy Junkies tracks you played me earlier. Both excellent, but sounding very different on my system I like the effortless soundstage and disappearing speaker trick your system plays. It'll be interesting comparing the Aqvox Blaze USB cable with both my current and new Mad Scientist cables.

Hi Pete, a very quick listen to the Aqvox Blaze cable in comparison with the Mad Scientist Black Magic revealed only very small differences, meaning they're both excellent cables! If I had to identify a difference, and it's quite small, it would be that the Aqvox has a brighter upper-mid to lower-treble presence region. It really is the tiniest difference that I could hear.
A (hopefully) stiffer test will come when the Black Magic Ultra arrives.

I should probably have mentioned that the AQVox cable was completely new and would have changed a bit over time. It was bought to go with the AQVox CD burner, but for now it will become the input of an Innuos PhoenixUSB re-clocker I bought to try in the UK system. I'm hoping not to be impressed as otherwise I'll need a second one for here! They also make an ethernet re-clocker too, but one step at a time! Anyway, the reason for this post is that I have spent today fiddling with the German system. As I have mentioned previously, although I use the Royd Apex speakers most of the time I do have a pair of Shihanian Arcs as well. Today I decided it was time for a swap over. They have many similarities in presentation to the Royd / Rega speakers, but also some differences. The most noticeable difference is that the soundstage presented slightly more forward than occurs with the Apex speakers. I also think the Apex (and Elas) deliver a slightly tighter position. However, they do a superb job with well recorded drum, especially bush-work and their rendition of vocals is very natural, but again without the razor sharp focus that the Royds deliver. However, this might be because I am using the Townshend Supertweeters and they are position slight off access at present compared with where they sit on the Royd / Ela speakers due to the lack of flat surface on the Arcs. I have ordered two stands designed for the Sonos One units which are the right height and will position them better. They should arrive on Monday so I will soon know if that helps. The other thing that surprised me was the changes to the sub settings that were needed, and I also had to increase the Supertweeter setting from 2 to 3. The sub had been set with a crossover point at about 60 Hz for the Royds (and this is similar to what I use in the UK for the Elas), but I needed to increase it to about 100 Hz for the Arcs and increase the output. I was expecting them to have more bass extension than the Roayds not less I used Musicscope and a calibrated Earthworks M30 and some test tones to check out what was going on and then made (and am still making) fine adjustments while listening to some 'test' tracks. I have also tweaked its position a tad too. As I have observed in the past, the Shihanians are superb for acoustic and orchestral performances and are very good on vocals, but are more fussy with rock and don't handle electric bass as well. Still it makes a nice change although I suspect the Royds will return soon - mind they are doing a stunning job with the drum and vocals on "You Oughta Know" by Alanis Morissette on the acoustic version of Jagged Little Pill at the moment. I will route the cables from behind if I decide to leave them in for a longer period.

Blimey, the Arcs make a stunning job of "The Trinity Sessions Revisted" by Cowboy Junkies!
I have also started to play with fuses again. The Lector VM200 power amp. now has a HiFi Tuning Supreme - Kupfer in the rear. I'll give it a few days and then maybe try an SR Orange again.
Trying to work out what to do about the fast blow fuses in the Arcs. Maybe I will try replacing the 3A ones in there with a couple of the 3.15A ceramic fast blow ones I have ordered to use in place of the two plain glass fuses inside the power amp. I figured that at least they will be less affected by any microphonic effects at least> No one seems to make a fast-blow 'tuned' fuse. I suspect I can get away with 'slow blow' in the speakers (and just be careful!), but I'm reluctant to risk it in the amplifier.

I'm wrong as it seems SR do produce a 3.16A fast blow fuse.

Fuses in speakers? Yuk!
