    Just took delivery of the newly prototyped Pure BiPolar amp by Spritzer. Seems its a new take on the Dynalo Mk II with BiPolar SuSy inputs. 
     
    Short first impressions - clean sounding with good, clear hard hitting bass when the recording has it. Typical neutral to warmish sound of Spritzer builds yet not sterile nor clinical. Pairing well with my Mojo as source and PM2 as headphones. This amp can accept single ended inputs (via adapters) yet produce a genuine fully balanced output via the SuSy tech.
     
    Needs some more run in time but its sounding good without the stress of tube noise and ground loop hums from my Glenn OTL (another firm favourite amp). Well done, Spritzer!

    Have you tried some stax amp like the 727 or 007? How does it compare to the stax amps?

    Sorry have not tried the stax amps before.

    Thanks. Have you tried any other stax amp?

    I’m strongly weighing a Pure BiPolar. Any chance you could give a detailed review of this now that you’ve lived with it for 3/4 of a year? I think this really might be the one for me but I want to hear a variety of opinions before I commit this kind of money.

    From memory the amp is pretty transparent and fast. Very little coloration except for a tinge of warmth (but that could be also due to my tube Dac). Sorry I can’t remember too well but I would say it is transparent to the source and drives both Low and high inedanxe headphones admirably.

    It sounds like you no longer have it. Pity!
