Mine ended up being a bit of a puzzle to assemble, but I like the solidity and visibility of the layered clear acrylic. It also came with adhesive backed heat sinks for the three hottest chips and wall mounting holes which I use in its garage closet setting.

The second photo is using a Jameco linear with ferrite toroidal core using standard S/PDIF. I later moved to using batteries and optical. And finally, the entire modest system using another battery with Music Hall DAC 25.3 and Crown XLS-1500 driving modified New Advents.

I ordered it as a kit when Welborne the Company was 'going out of Business'.... So, I built these Mono Blocks myself, and never have had a problem in the 10 years I've owned them.

Welborne did come through for me, but it took a couple of shipments and some misfires....

They Pissed a lot of folks off, by not delivering kits and parts. They had a Stellar reputation, before trashing it within their last year of business.

Too bad acrylic doesn't contain any of the RF radiation that your cute Pi generates. Probably okay if your main concern isn't SQ.

the unit were located within close proximity of other components as is more commonly found. I have a voltage sniffer which detects it's presence at about the three inch mark - far away from anything else.

At least I don't stack digital components directly on top of a preamp or power amp in my garage system. :)

for the Touch. I had no trouble getting the first one and it functioned quite well.

Acquiring a second one, however, was a different story. I had to report non-delivery to AMEX following a month after the charge hit my account. I was aware of reported "inconsistent" service from him, but knew if he didn't deliver, I would simply refuse to pay. AMEX agreed. :)

Can you enlighten me about your voltage sniffer and how it works exactly? Perhaps a link to a technical paper?

Many such devices are available. While their primary role is detecting AC voltage, they are sensitive to electrical field proximity and give an audible warning.

Mine is a Gardner Bender unit.

I am very sensitive to the false brightness RFI interference causes. Consequently, I incorporate sensible physical component distancing along with electrical isolation in the main system via dedicated lines, power conditioners and shielded aftermarket power cords.

You realize that those things are designed to detect active 60Hz electrical lines and not RF radiated by things that radiate RF, right?

In your opinion, is this an example of sensible physical component distancing?

Don't answer. The emperor has no clothes.

I think E-Stat uses the wall of his garage which should be fine.

Also, the DAC DOES have a metal case, after all.

My plastic cased Pi is about two feet away from the nearest other audio component.

I'd worry more about my metal cased Macbook Air causing RF problems before the I would the Pi.

and my sincere apologies in advance as my acrylic stand offers no RF shielding properties and probably lacks vibration control. Oh the horror!

For all the hoopla over how 1ft of interconnect cabling improved the sound of his system, you'd think that RFI would be considered an issue. Then again, you'd think he'd know how NOT to measure it.

Btw, The photo of how not to stack equipment and the photo from my prior post was from the OP's own web site. http://home.cablelynx.com/~rhw/audio/

Only someone who doesn't understand the concept of time would ask such as question based upon my collection of RPi pictures.

I think others will understand the first day's post chronology in its entirety. Or, simply by looking at the pic's time stamp. :)

Is that a BNC connector used for power in the left most unit? The mini USB connector sure is fragile!

Hifi Berry case, thanks to cut-throat for the recommendation. :)

 

RE: Show your Pi case(s)! , posted on June 8, 2017 at 06:40:21
No its a BNC connector for BNC output.

They are all powered via the GPIO connector though.

Since it is located the same position you've located other power inputs, I thought you might have used one of these using it as a more secure connector.

RE: Thanks, posted on June 8, 2017 at 07:31:39
Actually if you look closely you will see that it is located on the "Output" side ie next to the Coax and Toslink.

The others are all on the opposite side.

but is directly above the micro USB power input like the one dead center as well.

 

RE: Ok, posted on June 8, 2017 at 08:09:57
Yeah the one dead center does not have the Digi-HAT, so by choice I just put the power connector at that location.

Obviously you can put the power connector anywhere....correct? Its connect via wire not hard soldered to a board.

1) Moode via Digi+ optical
2) PiCorePLayer via Digi+ Pro coax
3) HQ Player NAA
into Gustad A20H.
I reiterate to the intimidated: None of these setups required one speck of Linux programming or knowledge to set up and keep operating.

Would you care to identify the role of each?

It appears there are multiple RPIs involved.

I was about to buy one of their Ultrapath linestages but after doing some research and reading of complaints here on the Asylum, I decided to do more digging then decided not to buy.

Welborne Labs operated out of a residence in Highlands Ranch, CO only a few short miles from our home back then. We have since moved. I actually drove by the home and it was in slight disrepair with lots of overgrown shrubs, trees, and a lawn that needed mowing. The garage door was open and it looked like they were packing to move. The neighbor homes were looking pretty sharp so I could only imagine that they had fallen on hard times.

The "business address" they listed was actually a UPS Store in Highlands Ranch, CO. I Googled it then went into "street view". I viewed the UPS Store in a strip mall next to a pizza place and Staples office supply. I visited that Staples when I needed something in a hurry. Welborne may have operated from a new location for a couple more years after moving from Highlands Ranch.

Welborne's home page says 1987 - 2015 but they were having problems a few years before 2015. Welborne still has their website up with links to product manuals so that was nice of them.

When I purchased the Touch power supply, the business address was a UPS store in Oklahoma!

My thinking was there was little to go wrong with it so long as I got delivery. First time worked fine. Second time around I purchased a Teradak unit off ebay. :)

For some reason I was thinking they had moved to Oklahoma, but I don't remember why. Perhaps you or someone else mentioned it a couple years back.

1) Moode via Digi+ optical - I use this one the least, mostly just to explore Moode and similar players. I haven't gone so far as to connect Moode to the main music folder on my desktop PC but have used a memory stick with good results. I like the accessibility to internet radio that Moode gives - It's the only way I have found to get the 16/48 Czech classical station to my main system (others say Logitech Media Server (LMS) can do it but I haven't been able to). I've never had a problem doing 24/192 via optical using the Digi+. I could see this Pi, running PiCorePlayer (PCP) replacing a Squeezebox (SB) Duet in my home theater room so I can send high rez to this system someday.
2) PiCorePLayer via Digi+ Pro coax - This box replaced my SB Touch by running PiCorePlayer on it. (LMS is run on my main desktop PC) What a great program, I really like it. The ability to tailor the sound based on the degree of linear to minimum phase behavior you want is just peachy. Why there is almost no discussion of this on the web I have no idea. I have been using LMS for a while and feed numerous SBTouches and SBDuets and SBRadios so moving to PCP was easy. One could easily set up a whole house distribution with LMS with PCP running on Pis...way cool.I think this box, via coax SPDF, sounds very very good.
3) HQ Player NAA - Simply using this Pi as an HQPlayer NAA. Often upsampling to DSD256. Hoping to do 512 into a Singxer SU-1 then I2S to my DAC but not sure if an NAA Pi can do this. Might have to look at a NUC. I have a Wyred Recovery on the USB path, but still find myself thinking that the USB from the Pi isn't quite up the the SDPDF I get from the Digi+ Pro. Hence the SU-1/I2S route...

All of these Pis go into the Gustard A20H, then CAT SL-1 pre You also see a pic of the excellent Digital Amp Company Maraschino Monos, Great amps.
Lots of fun.

Would you care to elaborate on this a bit? I too, have been a long term LMS user and currently have three music players and two video players accessing its library.

The link has the best description I've seen of the upsampling capabilities of PiCorePlayer. I too like the "I" setting, for Intermediate phase. Not too bright, not too soupy.

I guess I need to get my head around the notion of if and where to upsample - my Music Hall DAC 25.3 offers such with a simple press of a button.

Follow the link found here.

Be careful if you post pictures. If you test the unit's operation on top of your DAC for more than an hour (mine was there initially for two), you'll find individuals who will quickly criticize the location. :)

At the expense of repetition, this case includes three small heat sinks and has holes for mounting. Expect to spend a good hour with assembly. Each layer of acrylic has protective sheets on either side. You'll need an X-Acto type knife (I used a cheapo package cutter) to pull back a corner of the film for removal. Then you stack the layers one by one. Mine included a diagram which identified where each piece goes. My Digi+ board required a little bit of trimming of two layers to accommodate the opening for both output connectors. No biggie. The first pic shows that area.

I would buy it again.
