After learning about the Schwarz’s circuit Dima declared that it will be very simple to build into the unit a good quietly multiplex decoder as the plug in modules as a substitute to the original modules. This will change nothing in the Schwarz but t...

Guy,I absolutely disagree and I think there is a huge difference between lettings your wife to know that skin in her neck remind you sesame chicken and letting a play director know that his new production stinks. Of course we moderate our behavior in...

Here is another, simplified assault after some rethink and PSUD simulations.Rectifier: 3x1.2kV SiC per phase should do the job, actually 2 would do, but I'd preferto be safe. Bridge I don't want, as there would be 6 not 3 diodes switching1750V. 1.2kV...

It is fashionable among audio people to play with this analog, rewiring tonearms for instance. It always astonished me how masochistic this ceremony is and how many people dive into it completely voluntary.
Ok, let me explain you something. In MC an...

[quote user="drdna"]The question in my mind Romy is: why? I will be interested to hear your comment on what your goal was to learn about your system in introducing these and what the results are. After the extent to which you have describ...

Computer playback has no autobiographical value. CD, LP, tape etc have autobiographical value and sometime huge value. A location on HD has none of it. Computer playback has no unified standard and no reference in virtual world. If a person uses some...

OK, here are some follow up thoughts after the completion of the project. I am sure I will burn it for a month or so. I think everything will be fine, I do not expect any issuers technical or sonic. The way how the entrance to the corrector done it i...

Thanks, Paul.
I never saw this company. I did call today to the guy who run it and had longer conversation with him then I intended. Size and shape wise it was exactly what I was looking for. Unfortunately he does not do matching transformer b...

Jim,
in my corrector (Dima’s design with R2=50R) I made many experiments adjusting the VR1. Dima proposed 150V on 7788 plate purely arbitrary, what he did it he never ever seen 7788 and it was just a concept RIAA for him. After it was built and I p...

I am not a big fun of Dvorak 9th under Ancerl. I’m not big fun nether the orchestra’s balance nor the recording quality. Anyhow…
I do not think that that you need to worry PH-77’s accuracy of curves or the comfort to switch them. It looks lik...

Perrew,
I do not know if you use sarcasm in there but Lamm LP2 is not my bellowed phonostage. In fact I am one of the very few people whop do not like it at all. How much in what I do not like in Lamm LP2’s MM section come from the WE417 tubes...

Yes, it is a bit ridicules to have 4 boxes – a clearly money-raising project. Probably Lamm need to make it 2 chassis init with box #5 is to store manuals and box #6 to store the tube replacements. Talking about tube – one gain state with 4 paral...

What I find interesting is that none of the Japanese store that sell cartridges for domestic marker sell the Shelter 90X. Who knows, perhaps the 90X is the big conspiracy between Shelter and US importers who decided to capitalize on the success of Sh...

An interesting devise, They allow to adjust the midle point of the RIAA curve. I never have seen it and I wonder why would it be necessary or desierable?

With the recent changes on my configuration changes and employing the “End of the Live Phonostage”, in duty I re-thinked my analog playback. I got rid to arms and one deck, changed the mapping between the arms and phonostages and ended up with quite ...

[quote user="clarkjohnsen"]Yes, the 1953 Scherchen. For over twenty-five years I have hailed it as the best ever committed to disc. So let them laugh at me, I don't care.But the sonics were not good, and it was never remastered, because alo...

There is a new company out there that make some electronics. I do not know them, never heard anything that they do and do not know anyone who use their products. They have a phonostage that might be interesting.

[quote user="rafaroxlm"]As you may know the 7788 is a high transconductance pentode which should in theory be able to give higher audio resolution than say 12AX7, 6072 tubes in tube mic pre designs. On search here the 7788 was mention...

You know, I frequently tend do not listen operettas on LP. Operas are serious, dramatic, requires attention and dedication. Operettas are much lighter genre, no less wonderful but light and less “loaded”. I love operettas and I frequently liste...

…and since it is in LL line I presume that it might be right along with LL2 Preamp – not particularly interesting preamp. In other words it is most likely the “positively expected” and “might be interesting” continuation of the L1 and L2 line.

It is not a the thread about Allnic but LCR RIAA correctors, still there was something expressed in here about the Allnic LCR phonocorrector… and I feel bad about it. It is not that I don’t think that Allnic LCR phonocorrector deserve positive m...

Since Sound in new home is mostly set I kind lost interest to do anything “project-wise”. I play my music and I gradually tune ingredients to get the sonic mixture that I accustom to. Last two week I was slowly playing with my analog setup. Since...
