Per recent custom build music server.

This particular server build is result of number of individuals endeavoring to assemble the finest music server available. This endeavor began in 2017 with various modifications to mac minis. This evolved into assembling servers based on ATX (Windows/PC computer motherboards) boards. A number of these builds ensued over the following years, each one surpassing the previous. Greater knowledge base and incremental improvements in individual parts accounting for these server improvements. This particular server was the culmination of those endeavors late 2019, early 2020. At this point individuals involved in these builds determined diy route had reached it's limit, each purchased Taiko Extreme.

My server was the personal server of one of these individuals, subsequently sold to individual I purchased from. This individual also moved on to Taiko Extreme.

Previous owner continued to make improvements with addition of HDPLEX DC-ATX 400W and upgraded cables. HDPLEX powered with Paul Hynes LPS. Euphony Version 4 operating system and Stylus music player also installed.

In considering sound quality of this unit it was rather recently compared to Aurender W20SE in which this unit was preferred. At the point of that comparison this unit was lesser HPLEX power supply and Roon w/HQPlayer.

So, moving to present.  I have purchased JCAT Optimo S, the first 100% linear power supply ever for atx motherboards. Not going into much detail here other than to mention three discrete power supplies within one unit, each capable of supplying 23amps continuous, 30amp MS, microprocessor control power delivery. This unit weighs 55 lbs and comes with all looms of cable required to power atx board with relatively powerful processor. This was not easy undertaking for designers, providing that level of amperage with exact precsion is not easy thing to do, PC's have been around for more than thirty years, this lps is a first.

So, in recent weeks installed new modem, Netgear CM500, Broadcom chip based vs. ISP supplied Arris, based on inferior Intel chip. Netgear also has external power supply vs internal in Arris. Added LPS to Netgear, result is likely biggest bang for buck network upgrade I've experienced, and quite substantial for any expenditure. Simply greater transparency, resolution, and most importantly, more sense of ease, more analog like presentation, this due to lower jitter in Broadcom chip modems.

Also installed four Duelund CAST PIO tinned copper coupling capacitors in 300B amps, wow, relegates every single other audiophile film caps I've heard to distant second place. More transparency, resolving, but even more important, just far more natural than any of the others. I believe Humble cap comparison rates these like 3 or 4 notches above all the others, I'd rate the tinned copper even higher, they're like no capacitor, just so open and flowing!

Expecting new custom built ATX motherboard based server/streamer and JCAT ATX LPS  to power it in house later this week. Major, major upgrade on paper over present modded Mac Mini which sounds wonderful. Guys who built this server moved on to Taiko Extreme, only server they thought bested it. And this was with HDPlex DC-ATX internal power supply with much lower quality lps than JCAT. The JCAT alone cost $5700, 55lbs of intense goodness!

Apologize for not responding to some comments, not getting notifications. @jond Output transformers custom wound with silver litz wire.

Scott I am curious what output transformers you're using in your Tube Fantasy 300B mono's? And looking great!

Hi Dan,
We must have similar tastes, I've owned or certainly considered purchasing many components in your system.

Coincident had both single chassis 845 (mine) and mono block version for a short time, both no longer available. Perhaps they'll come back some day.

I do need to upgrade my vinyl, looking seriously at AT art9xa.

Thanks for the positive comments, hope you continue to enjoy your system.

Scott

SNS, I really admire your system. I didn't know Coincident built an 845 amp. I've been inclined in that direction for my custom-built Tannoys, but as of yet,  haven't found one that is affordable in my situation.

I have a DIY Garrard 401 with Dynavector 501 arm. I used a Zu Denon 103R for years, but, currently, I'm loving the heck out of an AT ARP 9.

Well, continue enjoying your well-built system, and the great-sounding music  it makes.

Regards,
Dan

@jaytor I modified Crites AA crossovers, first to A crossovers, which meant getting rid of tweeter protection, mods proceeded from that.

Yep, the Acme 300b just starting to really come along, at 80 hours now, starting to bloom, fill out, relax. I can tell these major upgrade from the Shuguang Black Treasure. Acme's would be real contender for your new 300B amps.

Cool system. Did you build the crossovers for the Klipsch speakers? They look pretty impressive. 

Are you still happy with the Psvane 300Bs?

I'm using Jelco TK850L with Denon 103R. I've been concentrating on digital side of system now for a couple years, analog has fallen behind, looking at Lyra Delos, Audio Technica  Art9xa, Soundsmith, some others to bring up analog to higher level.

300B tubes used Shuguang Black Treasure and Psvane Acme, Acme play on much higher plane. Still burning in the Acme, so final analysis waits, so far seem like keepers. I may post mini review on one of the existing 300b threads here.

@jond The amps are that much better with Acme, reaching potential with nice power tubes. 300b amp now ahead of Coincident 845, will need top flight 845 tubes to compete at this point.

sns

Nice looking system. I'll bet you've got a lot of synergy there.

What arm and cartridge are you using with the SP-10mkII?

What 300b tubes have you been able to roll? And did you write up your experience somewhere? Curious to see where you've ended up.

Awesome system sns! I would love to see a pic of your Tube Fantasy amps they sound interesting.
