build consideration for Zev V4 or Aleph 3

Hi all,

i'm thinking to build either one of the subject two amp.

i have an A-X in use, since it is really too hot ... such that i may only use it in winter or so...

that's why i wanna to build a smaller power unit.

i read the Zev v4 document and seems that Mr. Pass compare it's sound to Aleph 3, which is almost the best sound of the Aleph series (except the J ); )

So, what do you think? which one should i go? and what's the pro & cons of it?

Thanks in advance for your advise!
