Apologies to rixthetrick for the thread derail. I originally jumped in here as I was considering the Primaluna DAC at one time.
@erictal4075 , I own the L2 May DAC, and despite the original buyers guilt of dropping $5k on a dac, I don't regret it. Short of outright failure, I don't think I'd find a reason to "upgrade" in the future.
When compared to the internal DAC of my CD/SACD player (Yamaha cd-s2100), the May presents a 3D illusion in the room, with much better soundstage depth, width, and thrust. Swings in music are more dynamic, whereas the Yamaha's dac is more 2 dimensional, and lacks the dynamic swing that pulls you in. The Yamaha sounds "nice", relaxing, and polite, but it does not engage.
I'd place the MP-D2 somewhere in the middle of these 2 experiences. While the pricing on the MP-D2 has gone up, I found it a steal at the $800 black Friday price i paid. I've not heard the Evo 100, but have to believe the MP-D2 would compare favorably in sound quality with the right parts/tubes installed. The PL casework is better, more robust and in my opinion better looking than the MP-D2, which has odd dimensions, thinner gauge case, and decent, but not outstanding build quality.
