So then you are talking about the performance of the amp by looking at the spec sheet. And now that you've clarified it, you're referring to power output only and not sound quality. That wasn't clear in your other posts.Thanks for finally seeing it my way. I am somewhat surprised by why you couldn't see my point the very first time I posted it. I will repeat my exact quote again and note that I specified Power Amp Section. Further I said almost identical; not exactly.
In fact, I checked the specs and both units are rated at 100 wpc into 4 ohms. So, their power amp sections are almost identical.Sorry if the above wasn't clear enough. I guess I should learn to write better or run the risk of soliciting your unwanted comments. Hopefully the OP knew what I meant though and from the sound of his last post, I believe he did.
And since the PM 17sa is built to a higher standard, why wouldn't it sound better?
After all, that's the most important part as it was his question that I provided a positive response to.
