Coincident vs Lamm

Markus1229, how much is he asking? If the price is really good, then there would be little downside in purchasing them and trying them out. Well priced Lamm's are always in demand should you choose another direction.

Hi Markus,
I see your dilemma, it may still be worth your time to travel and at least hear
these acclaimed amplifiers If you can't get them in your system.
Brf's suggestion is good, only problem is you'd have to sell your
Frankenstein to swing the deal (and what if the Lamm doesn't suit you?).
You have a terrific system now but I can certainly understand your interest
in the Lamm SET as well. You're thrilled with the Franks so this is your
template. You can listen to your friend's Lamm system and try to
extrapolate to the best of your abilities.
Charles,

Markus1299,
I would suggest that you ask your friend to have "you" bear the cost of shipping (plus insurance) both ways (if you don't like it) to try it in your system. This way, he has nothing to loose. If he is still not willing to go that route, then I don't know if he's truly a "friend".

The amps could get damaged in the shipping and at this guys house. I would not do this for my friend because then if something happens the friend may or may not take care of the damages.

Insurance would presumably cover any potential shipping damages. Ideally the Lamms need to be heard in Makus' s system and compared to his current amplifier. You just never know until you hear a component with your own ears.
