The 'tube-transistor' enigma by MC carts?

Nandric, I suspect the comparison of different cartridge construction to tube vs solid state is likely a red herring. Tube phono sections do not have to have higher distortion, and some transistor phono sections OTOH can have quite high distortion. There there is also the question of what distortion is important to the ear and what is not. Research has shown that all humans detect distortions in the same way- but that is a topic for another thread.

In phono cartridges, you are also faced with loading issues, and the ability of the tone arm to allow the cartridge to track. These variables play a huge role in the resulting sound you get- Raul is absolutely right as well about the design tradeoffs that a cartridge designer faces, along with the execution. It is not something that can be so cut and dried.

Dear Raul.We are waiting for J.Carr but I made some investigation in between.There is obviously the problem
of the language we use to describe 'sound' so no wonder
the musician invented they own notation (Pearson also
mention this problem and trys some Chinise metaphors).
Despite of this we are aiming,it seems to me,at 'the same'
goal. Your description was: 'more linearity' my was 'more
neutrality'. But I attributed this,say, 'quality' to the
'not-iron bobbins'. Not I but the Swiss guy (from Benz)
stated that Ortofons SPU is a'classic example' of 'iron-bobbin'construction. I knew that there are persons who
will kill,so to speak, for this cart but also that the
majority don't care about this cart.But I had no idea why.
So the information from the Swiss 'lightened' something in
my brain. 'Spying' is also 'a form' of investigation so I
deed some 'spy- work' at your cart-collection.Alas nobody
will pay me on 'cent' for my effort. One 'second alas' is
the fact that I deed not see SPU of any(Ortofon) kind there. So my quess is:someone with such an collection can
unlikely have forget or miss such one 'item'. So my second
quess is:there is something about the SPU that Raul don't
like(?).
BTW there is one 'special' about the SPU on our forum.
About the SPU I will quote two statements:
a.'unusualy high output and a soft IRON circuit with high
saturation';
b. SPU Synergy versus Jubilee. SPU 'more weight&solidity
but not the air of the Jubilee.
You mentioned Ortofon in the context of 'bobbin kinds'and
you named 'armature' and 'carbon-fiber' as ,I assume,the
material of which the 'bobbin' is made.
HI-FInews (from UK) has payd a visit to Ortofon as a kind
of introduction for the review of Windfeld (Dec.2007).
The information:80% are MM carts. The MC carts are produced
by special 'force' with the ability to 'wind' with accuracy
the wire on the 'bobbins'. The 'top' carts are an fraction
of the production and SPU is a small part of MC carts.
I don't know if you know that Windfeld has the same diamond
as your 7500: Replicant 100.
Windfeld is 'basicaly' Jubilee with some mod. As mentioned
the Replicant (more extension in both 'extremes')and some
small mod. to the 'bobbin' so that the coils (copper-gold
alloy) should be more precise wound. The result:0.2 dB
channel sep. and Fre.20-20000 +/_ 1dB.
So there is still progress in the 'art'.

Cheers

Dear Nandric: Yes, fortunately there is progress.

SPU: many years ago I owned and change it for other cartridges that ( in that time ) like me more.
Last year I had two SPU experiences ( unfortunately not in my system ) and I can't find nothing that motivate to go for it. To be fair about maybe it is time to try a listen in my system, yes why not.

Regards and enjoy the music.
Raul.

Dear Atmaspere. Very strange that the answer to my conjecture should come 'throug' me. The Swiss guy (R)was
acquaintance but became a friend so I 'abused' this to
ask more questions. Before stating the aruments I can say
in advance that we all (Raul includes)are right but for
different reasons.
My conjecture about 'tube-transistor' regarding the 'harmonic distortions' is correct. But the distortions
from 'iron-bobbin' are much less then from tube-amps (caused by outputtransformers). You are right regarding
'your variables' and Raul regarding the 'complexity' aswell
the personal preferences ( an constant ,it seems to me,in
hes arguments).
Your mentioning about our 'hearing' is an enigma to me:
those are phisical events and of course we hear 'the same'. But we must 'interpret' what we are hearing and
then we may have different preferences (see Raul about SPU
from Ortofon). So,for example, Van den Hul is 'tuning' hes
carts to the customers preferences. I.e. one can order by
hem what one like.
The Swiss is,as I mentioned befor, for 'it depends ...
approach. I was wrong to suppose some kind of 'objective
facts' behind our preferences.

Cheers

Dear Nandric, I sincerely hope and expect that the Jubilee et al has better than "0.2db" channel separation at any and all frequencies. Obviously, that was a typographical error on your part. But what were you trying to write?

Have you heard both the Windfield and the Jubilee? I am interested.
