Seems to be that this circuit was already discussed in 2009 and Edmond Stuart has simulated it. See the Blowtorch thread.

Have now been going through the BT thread, and did not find any sims,
I think that the that340 with matched dual npn-pnp could be the medicine if that kind og input is to be explorred

No, that was in 2009 as far as i know. I found this interesting, but this is not important at the moment. I have enough to do.
Just today. I wanted to try out the MM stage of the Tanzmusik. I had visited Fink Consulting some time ago and Karl-Heinz gave my an AT95E. He said something like "it is so good that i do sometimes not know what the fuzz is about expensive MCs". That is strong medicine but i was curious enough to try it out. I put it in my Goldring table that is the cheapest REGA with a wooden platter. It is somewhat modified but this again is not important. The sound i got really surprised me. In a very wide midrange everything is fine. The stage is wide, deep and high. At the extremes of the spectrum there is some loss of grip and punch in the bass and the upper treble is extended enough but a little bit fuzzy. It does not sound as energetic or spontaneous as my reference table either but it is interesting and sweet enough to draw my attention. Fatigue is low too so there is no excuse any more not to try vinyl if you are bored by your crap DVD player. Buy a used REGA or restore a Lenco L75, put this marvel of a bargain in and you are set with maybe 150,-€.

That makes no sense to me. Ones i have adjusted a cart in my Triplanar it is "holy" for at least two years. It is just too stressy to find the sweet spot and then loose it. Just smash your "Sparschwein" and buy that damn thing. I found it new on Ebay for 19,98€. If you do not like it i buy it back from you.
