When I was in discussion with Thorsten I actually had the low gm Telefunken EF 804S in mind. This was a valve specially developed for their studio microphone preamplifiers, designed to have minimum self noise so probably the best thermionic amplifyin...

The 834P was a revelation for me, being a circuit that I would have dismissed as "old hat" (Feedback? 12AX7 cathode follower? Do me a favour!). I like it so much that I intend to build an "enhanced" copy a la Thorsten/Carsten for reference (and enjoy...

I am really not an expert in digital crossovers. I rented in past a few, inducing the Behringer DCX2496 that Thorsten mentioned. I less was concern at that time about the unit as prototyping crossover but rather was trying to learn if the digital cro...

OK, Guys.
I have sent the “winner’s CDs” to you. I do not remember to whom but for some of the Brits I put 2 CDs. So, who get the second CD then, please, pass a copy to Thorsten Loesch.
I hope you enjoy the Music and thanks for visiting on my site....

[quote user="Romy the Cat"]I might be not “getting” what you are doing but it looks to
me that it is not near close to “CEC TL0X vs Berkeley Alpha”. The Berkeley
Alpha is just an interface to get stream of DAW but CEC TL0X is digital transport. We...

The news just come inhttp://www.amr-audio.co.uk/html/pr_ph77.htmlThorsten use to tell me that his ambitions phonostage project will be coming through in fall of 2008. Well, it is late but it is there: the AMR announced their new PH-77 Phono Equal...

Allo,Well, the divider may certainly be responsible for some softening of transients - in particualr, what values are you using there?Also, the received wisdom is that silver micas are created far from equal; no experience with them myself but I beli...

I'm a phono moron, but having had several phono preamps, I think I can understand what finds Romy right in the EAR 834P, which I love. I'm not as skilled and crazy as to try to make all the Thorsten mods in it by myself, but I've tried some tube swap...

[quote user="Thorsten"]1) It does so in your system context.2) It does so to your personal prejudices how music reproduction should sound.[/quote]T, I do not want to derail the thread into a different direction but still I would allow myself to make ...

[quote user="Thorsten"]Forgive me for saying so, but since Bishop Berkley and David Hume it should be well clear that there is NOTHING WHATSOEVER that is actually objective, at least as long as we are subject to the limitations of matter and the huma...

I guess Thorsten is laughing since he should be the main receiver of TdP email. Popularity of a product is a double bladed sword. I do hope that sales of EAR 834 phono stage increased notably after Romy decided to make that circuit into his "end of ...

Thank youxandcg do you think Voyage MPD/ALSA/Ronald Config is not bit perfect? or you think it is not good?AMR (thorsten) guys in munich 2017 recommended my friend to use Volumio . Volumio use Debian/MPD/ALSA and they claim it is bit perfect.I think ...

Thx for this well written and highly educational piece Thorsten! It
appears that Romy is not very fond of the Audio Consulting
transformers, could you give your opinion regarding those? What is your
opinion regarding the use of pure silver wire in...

[quote user="Thorsten"]If you do, do seek out old Air dielectric AM tuning Capacitors. You only need 110pF & 330pF, both can be found suitably. Once you tuned the RIAA to perfection simply superglue the shaft in.... I used to use that trick in pr...

[quote user="Thorsten"]I have kept the 600R arrangement, but I cleaned up the circuit a lot. The new stuff was posted over at the AudioAsylum, not a place you are terribly fond of. If you still have the Phonostage you build it might be worth rolling ...

Ahoy there Thorsten, you took your time getting here!
Yes, obeissance in the general direction of Huntingdon. Ol' TdeP certainly made a Grand Master move with the 834. Building with the air variables will allow tuning for the 102 very nicely too.

Thorsten Loesch who came up with the mods, details what caps and why on the first page of this thread. Lacking interest for multiple years of auditioning caps, I just built it that way (2012 or so) and have had no urge to change anything. Romy has pi...

[quote user="Thorsten"] So, at least in commonly observable and observed terms and when used as intended the S&B line transformers are notably more capable at low frequencies than your LF OPT's in the Super Milq.[/quote]

Here is the signal box:The design is double mono past the VR's. Including the bias.
The coupling caps are Arcotronics KP172 from RS-Online, quite prised by Thorsten Loesch. THey are sitting on
sorbothane pads. The air caps are: 1) 365pF some +/- s...

Hi Thorsten,
I understand what you are saying and with regard to the particular preamp in question and you may well be right as there is no mention by the manufacturer what brand of autoformers are in use (or if they roll their own). I am curi...
