Hi there... This is my first post to this website and community. This is an old thread, but I couldn't resist responding. It will probably be my last post as I don't think it will be taken very well. But, this thread is insanely negative and without any real info or substance. Just negativity and a lot of conjecture. For those who are unfamiliar with this amp and Mjolnir Audio as a whole, it is the brain child of Birgir and Kevin Gilmore. Two of the most respected minds in the hobby and community. Both responsible for some of the best sounding amps you can either build (if you are a DIY'er, or buy). They give their time and their mindshare to the community, they provide their designs, and Mjolnir exists as a business solely designed around the idea of giving back. Frankly, they deserve better than what I read above.
The Pure BiPolar is a variant of the Dynalo design ethos which has produced the Susi Dynalo, Dynahi, Pure BiPolar and the CFA3. It is an extremely efficient amp that sounds amazing. All of these variants sound amazing. They are extremely clean, and musical; with incredible pacing and timing. If you want to see how this amp measures, and read a review, you just have to look. Bob Katz reviewed and measured it a few yrs back. Here is the link for those interested.

His review is of both an electro-stat amp as well as the Pure BiPolar. It may not be agreed with, but at least it will provide those measurements folks above were seeking.
I respect everyone's opinions. But, the consensus on this amp is not clear. I'd take this amp over most amps out there. I have put my money into a CFA3. It is pure amplification bliss. I am personally looking for equipment that can take me to my musics center. Unravel the complexity, find the pocket and take me to the venue for a visceral experience.
I didn't write this because I want to disrespect the fundamentals of ASR or those who subscribe. I respect this website and those that use the information here to make sound purchasing decisions. I just don't feel this thread is productive. I am not an engineer, nor am I a scientist. I am a music lover who has spent the majority of my life seeing live shows. My experience with music and this hobby has led me to use my senses to guide my choices with my hard earned money and the equipment I choose. In no way do I feel my way is the right or only way...
2 cents from a dissenting opinion... I apologize for upsetting the apple cart with my first comment to this community. Thanks for listening.
