A fit of Audiophilia


I am an 81 year old retired software engineer who still dabbles in that activity and am stuck trying to find a minor bug - which has nothing to do with the post except for being the reason for a glass of wine and the striking of Audiophilia.

I started to wonder about different file formats, external clocks etc.

A telling track for my critical listening is the "Bless the lord" from the Sveshnikov 1965 recording of the  Rachmaninoff All Night Vigil.  This has deep Russian octavist voices, a wonderful choir, the intense emotional voice of Klara Korkan and was recorded, I believe, in a basilica.  

In addition to the LP (which wins) I have a DSD128 and PCM 24/192 recordings.  Level matching the digital sources was tricky but playing the DSD at +5.5 dB was as close as I could come. (DSDs are usually about -6dB to avoid stability issues near 0dBfs).

The DAC is the Esoteric K-01XDSE which is a ΔΣ device and so operates internally in DSD 512.  I was listening with 4x upsampling, PCM filtering M1, and DSD filtering off.

The  PCM won, its slightly higher resolution yielded a slight increase in (surprise) resolution.

Conclusion unless something was mastered at better then DSD 128 if PCM 24/192 is available, use the PCM.

I then tried the experiment with and without the external SRS FS 725 clock,10 MHz, sine wave, 50 Ohm.

The K-01xdse has a very high quality OCXO clock but spatiality, these sense of the singers as 3D people, was noticeably improved by the external clock.  The FRS 725 uses the same physics package as Esoteric used to use in their $20k clock (they now use an OCXO clock at a slightly lower price). Conclusion, an external clock may well be worth it.

I do not have a spare $16k to compare the new Esoteric G-01XD with the FRS 725.  But the Stanford Research Systems unit is a bargain.

My clock cable is an entry level priced component usually used for uhf broadcast application, so now I am wondering if I can get even better SQ with an "Audiophile" clock cable, I am thinking of the Shunyata Theta or the Mutec PSC 50.  There are some insanely prices Shunyata and Esoteric products but ...

After all that the 60 year old Melodiya disk has a richer, deeper timbre and greater spatiality - but perhaps that is the effect of the Koetsu RSP/Sutherland Dos Locos front end.

@mahler123 I did not know of the Adam Fischer cycle, which is why I appeared dumb.  I found them on Presto;  I listened to #2 but it did not grab me.

 

Yeah the Adam Fischer cycle initially excited a lot of critics because he apparently tries to be as idiosyncratic as possible, an understandable decision when there are so many competing cycles.  The two that I streamed left me cold.

  I have Ivan and the BFO recordings of 1-4.  They are more mainstream and fall into the good-but-not-exceptional file.  The competition is fierce

Sometimes and often threads do depart away from topic but in doing so on the flip side we glean a bit of the person posting. The cloaking of identifies on AGon fora is to me a bit disconnecting.

This got me thinking; is audiogone more of a database platform or a community platform? To me, at its core, Audiogon feels like a hybrid. While it functions as a massive equipment database and marketplace, its heartbeat is the community. However, alas there is a recurring fracture between the site’s structure and the way people actually build relationships. Mostly this is to prevent end running Agon’s fees. Duh.

1.) Zee Value of zee “Meander” Das ist gott. Oui?

Strict site moderation keeps things organized alright, but there is a “hidden” cost to keeping threads on-track. When a conversation meanders, it moves beyond gear specs and into the personal. It’s in these "off-topic" moments—sharing a passion for a specific genre of music, a record, a life history, or something else—that we actually peer into the character of the person behind the screen. These are tangents and the building blocks of genuine connection. I can say I feel like I actually know who a few members are. To date the tally is three point one four folks and counting with a side of ice cream.

2.) The Privacy Paradox

The "cloaking" of identities on the Audiogon forums creates a sense of detachment. While pseudonymity offers privacy, it to me can feel disconnecting in a hobby that is so deeply subjective and personal. Without knowing the person, the advice can sometimes feel like it’s coming from a robotic vacuum rather than a peer.

3. My  Conclusion

If Audiogon were just a database, it would be a cold cold, transactional tool. It is the very act of "wandering off-topic" that transforms it into a community. By sharing personal tidbits and interests, members move from being anonymous buyers and sellers to being genuine enthusiasts with shared histories. Party on Garth.

At eighty one years young (pens the seventy years old tame fauvist gent..please take avuncular pity on me) I can tell by your writing your cabbage is working well and way above average. The spousal MOMA thing sheds cool upon you both.  As I kid I met Alexander Calder but was too young to realize how lucky I was. Not surprisingly I have become a life long fan.

On topic…kind of… taking a break from Jazz..Beethoven first symphony (Deutsche Grammophon) is on and it is on loud. Those welling up crescendos thrill.  Same as it ever was; taking off the top of my head.

 

@wsrrsw I do hope this is a community!  Where I live most music lovers do not seem to be interested in the quality of the sound.  The only serious one of whom I am aware owns a local company.  Indeed there seem to be few who have any interest in "classical" music so I find this forum to be a major resource - for sustaining my sanity.

It has always seemed to me that a good conversation ends up far away from the original topic and I hope that on this forum this is not viewed negatively.

Audiogon is a commercial enterprise, and we pay nothing for the use of this forum,  so I have no issue with selling being a breach, fees paid by sellers and advertisers allow to have this platform.

I do thank you for your post.
