The Thorsten’s mark.
fiogf49gjkf0d

Yes, Thorsten was the man that made the initial modification in the EAR 834 and I need to note that it was not redesign of any kind but juts basic modifications and admitting the unnecessary things. Even though Thorsten is the industry person he did not play any game sand posted his write up open and public. My contribution to the projects was supplementing the EAR 834PT (“T” comes from Thorsten) with no dielectric capacitors (air caps) and bounding it with ET-2 transformer that make great phonostage to be “End of the Life” phonostage. I do not particularly care about my priority in this process as I do audio for MYSELF. All of those industry idiots do not get that for a person who does audio excessively for own needs all their stupid self-pomposity is very much irrelevant and their pretentiousness screaming is just a noise to me.

Still, do not discard behind the stupid TdP behavior the elegance of 834 TdP’s design and the quality of 834’s sound. > >

Sound beats engeneering

3)      The common mode filter you have at the PS’s input- why do you use them? They do eat some dynamics. As many time I removed them from all imaginary components as many time I witnessed better sound.



After a long break I'm slowly comming back to my system. Only now I've found the time to check that and I must agree with Romy: Removing CM filters, MOVs, arresters the rest of the engeneering crap (apart from the hour meter) from the power lines has cleaned the sound, its more emotionally involving, direct, the dynamical contrast does seem better. The change was rather subtle but noticeabe, in a bit similar direction as my experiments with vibration decoupling- some subtle veil got removed.

Engineering Crap
Yes, an ongoing theme here at GSC: If it sounds good, it is good.  Conversely, no matter the "logic", and no matter the "technical genius" or "technological breakthroughs", if it sounds bad, it is bad. Likewise with any sort of "logic" or "intuition" that is not actually borne out by acceptable sound: it is not good.  The problem with the empirical/subjective method for audio is mainly time/money, also the Big Problem that the listener's tastes are required to make the judgement calls in the first place. Of course, this is antithetical to most engineer's ideas about who they are and what they and their ilk stand for; hence the discussions on their forums vs. here at GSC.

Best regards,
Paul S

Its not that it sounds "better"
it's more similar to removing say some delicate wool from your ears. I guess some recordings benefited from a bit of the veil but then its a problem of the recording.

In this case I hear an increased recognition of low level details (e.g. when musicians take air in your hear it as taking air in), which
I'd promote to sth more objective than just down to the taste. Anyway, vinyls kept spinning.

Burn, motherf....r, burn!
It took me 5 freaking years to fin-anally install a second set of SUT's in my EAR834. 4 out of those 5 years was waiting for Tribiute Pieter to make me custom silver SUT's on nanocrystaline core. I even found him the wire. I went boutique and the new input path is silver WBT, Pieter AG SUT's 1:12, silver wireing from Neotech (the blue cables) and a TKD switch. After bitching at German mafia I finally went their way too as it's the only switch with a solid silver contacts. The switch was Paul S treated with all the contacts polished and protected with a dielectric grease (Paul I hate you for teaching me this procedure - it's such a  pain). Now the path is being burned in. I found an ingenious way to do it: inject the signal (Hagtech's frybaby) to the input tube's socket and close the circuit with some 6.8R resistors at the headshell. This way  all the path is current loaded including the tonearm wiring and the tonearm cable. 10 more days of burning (due to travels) and I try it! It will serve for a FR64S+Fr7f combo, connected by AQ Leopard.

And who wins the prize for the least optimal layout? Meee!
