Morch DP-8 arm on a Helix Two turntable

Yes, Dohmann Helix Two.

Hi Vassilis_t

The Morch is a mass loaded unipivot arm with a spindly arm tube. It is unstable and nowhere near stiff enough.
The Helix two is an incredible turntable. Wait until the vacuum platter is ready. If you talk to Mark Dohmann he will tell you not to get that arm. You can email him directly.  The ultimate arm for that table is a Schroder LT. They sell the Schroder CB but the LT is the one for that table. Great
table!

Mijo, Admittedly, I have never owned a Morch tonearm, but they, particularly the model 8, are very highly regarded among those who do use them.  I don't know how you can dismiss it out of hand in this case, unless you have heard one.  I know you categorically dislike all unipivots, that is your bias in this case.  Can you point to even a negative review on the internet to justify your advice to the OP?  The Morch 8 is the one I would choose over all the other Morch tonearms, were I in the market.

I'm pretty sure that Mark D will tell you that the Schroeder CB-1 is the best value for his turntable and that is why he supplies them as the standard choice for the Helix 2. The Schroeder LT is a another, much more, costly alternative that brings more to the presentation. Last time I corresponded with Mark D he was also looking into trying the Reed 3P as an alternative. 
My advice would be to email Mark directly and get his opinion on the Moerch arm. He is very responsive to inquiries and is a great person to bounce ideas off - he will give you his unfiltered opinions. Congrats on the turntable-it is an end game deck for sure!
