Parasound A21 and A21+: Significant Improvements in SQ?

I have the same question and also wonder how the A21 + fairs against the JC5, Also Is the new A21+ a John Curl update? One of the two will hopefully find its way into my setup to replace my A21 which really can't fault after its many years of wonderful service but the journey must continue.

Great info guys , looking like the A21+ for me.

I have the Jc5 for about a month now and the darn thing is still breaking in! Now having said that, this is just a first rate amp period! Out the box , I questioned the whole upgrade process, two weeks later I started upgrading everything around it cables,dac etc.. (JCP 2 bypass is being saved for as we speak) The integrity of the soundstage is so solid on a three dimensional axis., images are palpable, musical timing and flow can produce goose bump city. Volume be  it low level listening or cutting loose the music just remains stable and no hint of dynamic compression  just unbelievable. I"m so glad I went all in on the Jc5!
