Dear Nandric, it was a really sad and dramatic end for Klaus Renner. And yes - since DAS OHR was literally his "baby", there was no way it outlasted it's father and founder. It was one of the very few magazines ever totally independent from advert...

Dear Rnadell, the "x" features silver inside wiring and a second counter weight. Cheers,D.

Dear Nandric, dear T_bone, I discussed the FR-64s alignment parameters briefly with Klaus Renner (founder and editor of DAS OHR who sadly passed away while still in his thirties in 1991/2) in the mid-1980ies. Based on initial proposals of A. Wagne...

Dear Pryso, no problem. My "question" was rather ironic and could easily lead to a misunderstanding. Mea culpa.Cheers,D.

Dear all, "that Dennesen designer" was Francis G. Dennesen himself, together with Richard Wilson, Roy D. Toulan Jr. and Peter Madnick. Cheers,D.

Dear Pryso, as D. read the Dennesen patent paper and measured the alignment spot distance to spindle center with a sliding caliper back in 1991, he knows since 20 years that the Dennesen follows Löfgren A/Baerwald IEC.But it was certainly funny to...

Dear Halcro, to avoid any misleading info here, let me state that "my" calculation for the FR-64s gives - even with VE calculator ...;-) ..... - for the last 66% (i.e. 2/3 of the grooved area) of the record an average of 40% less distortion than B...

Dear Genesis168, despite what some here on Audiogon did say past early winter in a deleted thread, the original Dennesen Soundtraktor is 100% Löfgren A / Baerwald IEC."My" calculation for the FR-64s has nothing to do with Stevenson.The original ma...

Dear all, just out of curiosity - does anyone know, what calculation is used with the Dennesen Soundtraktor ?Cheers,D.

Dear all, the UNI-Protractor does feature on it's main frame laser engraved the inner radii for both IEC and DIN standard in a way that if you place it on the record, you can immediately read-out what is the inner groove limit of the record.Thus g...

Dear Halcro, the change to 231.5 mm mounting distance (and thus effective length, offset(slightly) and overhang does indeed result is a lower overall distortion level for about 74% of the grooved area compared to the "original" specification in th... 
EMT 927 vs. Micro Seiki 5000 or 8000 - different?
Dear Nandric, indeed - essential in our modern times and as such a result of evolution and the need to evolve to survive. An bengal phrase says that it is only the most quiet moments that one can hear a divine voice. As there are no more truly qui... 
EMT 927 vs. Micro Seiki 5000 or 8000 - different?
Sounds a bit like back in 1982 when the introduction of the CD was hailed as the perfect sound forever ......Time went by.As always.BTW - did anybody ever noticed, that life itself is full of "noise" and artificial by-products, which most of the t... 
Uni-Protractor Set tonearm alignment
Dear T_bone, you hit the nail on the head. For instance any derivation from a given tonearms design inherent offset angle results in an alternation of it's mechanical model - here it results in an additional breakdown torque, which has profound ef...

Dear Jj2468, the linear tracking tonearms - in any incarnation we have seen so far from Rabco, Denessen, Goldmund, Versa Dynamics, Air Tangent, Eminent, Forsell et al -displayed mechanical issues, periphery problems and stability problems which di...
