Parts Connexion Modified GCPH vs Unmodified

I'm lucky enough to have both stock and parts conneXion modified PS Audio GCPH phono preamplifiers... So I figure why not finally write up a proper comparison.

A bit of background info:

https://forum.audiogon.com/discussions/impressions-of-ps-audio-gcph

First, a quick note on what I don't like about the modified GCPH. I hate the WBT-0210-Cu RCA connectors... Yes, they are probably electrically superior products, but the ergonomics suck. It's why I use Kimber RCA connectors on my DIY projects.

It's also worth noting that, as with all PS Audio Gain Cell gear, you want to make sure you have adjusted gain on the back panel such that the volume level is "correct" with the gain cell adjusted to between 11:00 and 14:00. Think of the gain cell as a tool for fine tuning output level, not as volume control.

Test Systems:

VPI Scout Turntable
Dynavector 20x2h Cartridge
Parasound JC2BP Preamplifier
Parasound JC1 Amplifiers
Mogami Gold Balanced Interconnect
Signet Maximum Transfer Unbalanced Interconnect (isn't nostalgia great)
Pear Audio Speaker Cable
PS Audio PPP Power Regenerator
Usher BE20 Speakers

Technics SL-1210M5G Turntable
Sure M44-7 Cartridge (crazy high output) 
Dynavector 20xH Cartridge - Soundsmith Boron with Nude Contact Line Stylus Retip
First Watt DIY B1 Buffer Preamp
Bryston 4B-SST Amplifier
Magnipan 3.6R Speakers
Transparent Audio Speaker Cable

So... how does it sound? Stay tuned...

Repairing KRK RP6G2 Rokit 6 Gen2 Speakers

I often browse electronics on craigslist when i need to momentarily 'veg out' at my desk. Yesterday i came across a pair of KRK Rokit 6 Gen2 speakers. There were a few things about this particular listing that caught my eye: The seller claims one of the speakers has a "capacitor issue" that he cant fix himself The ad claims these speakers are Rokit 6 Gen3. the screws on the front panel and the text on the back are a clear giveaway that they are in-fact Gen2.  I wasn't really looking to buy speakers, but if the issue is a "capacitor issue"... This looks like a good deal. And it beats only using headphones at my desk all day (although i love my headphones).  I had a nice pair of Dynaudio BM5A's for the desk that i used with a Benchmark DAC1. But i sold both the Dynaudios, and the Benchmark last year... These KRK's aren't likely as good as the Dynaudios, but sometimes a good deal now is better than nothing. And in this case, if i ca

PS Audio Directstream, DS MKII, TSS : New DAC or Mods?

PS Audio has been making the Perfectwave digital to audio converter (DAC) for quite some time, in fact, it is now at the tail end of its third incarnation, all using the same casework.  It started with the Perfectwave DAC back in xxxx, in 2012 it was upgraded to the Perfectwave MKII, and then, with the introduction of Ted Smith to the PS Audio Team, the Perfectwave Directstream (aka DS) followed in 2014.  The DS has remained PS Audio’s flagship DAC since 2014, roughly 7 years, with all upgrades being free and applied as firmware updates. Even more impressive is that many audio journalists and audiophiles still consider the DS to be among the best sounding, if not the best measuring, DAC’s on the market.  Full disclosure, the PS Audio Directstream DAC is my personal reference. From what I gather, the last planned firmware update, Sunshine (named for sunshine peak in Colorado) for the DS MKI is scheduled to arrive by the end of April 2021… Though, according to a representative of PS Audi

PureAudio Lotus DAC5 Review

Work In Progress Review: Background: There isn't much info on this DAC out there yet, but i expect that to change pretty quickly. Here is a foreign language thread i was able to track down: https://translate.google.com/translate?hl=en&sl=zh-TW&u=http://bbs.audiohall.net/viewtopic.php%3Ft%3D11656&prev=search When researching this DAC, I wasn't all that impressed by this unit containing a single ES9038PRO as opposed to some other units that use one for each channel, nor was i impressed by the claimed SNR of > 110db (which represents approximately 18.3 bits of resolution - 110/6), even the ifi micro idsd black claims a SNR > 117db (19.5 bits of resolution - 117/6)... But the fact that the opamps appear to be inserted into sockets for easy rolling is quite interesting, it appears this unit was designed from the ground up for the "tweak" enthusiast. As a benchmark, i typically look for claimed SNR >= 114db (19 bits), and prefer to see clai
