Compared with the previous model PA0901A or miniwatt N3 EL84, PA1501A 6AD10 sounds more powerful, smoother, more musical and details.

I've enjoyed the original four tube S1 since it first came out. Looks like it's being produced again with the same tube compliment but in a different case. I wonder how it compares to your new two tube version?

I thought the S1 sounded better than my friend's N3.

The circuit of PA1501A is a new design. APPJ makes use of the advantages of the 6AD10 double pentode. The sound of PA1501A tends to be a wider and deeper sound stage and more bass than PA0803A.
Thanks.
