Pass Aleph 3 or 5 for Proac 1sc

I used an Aleph 3 to drive my NHT 3.3's for a time. I was mostly interested in testing out the Aleph line of amps. The 3 is a great product, but it didn't have the headroom or bass control that I want. I've not heard the 5, but my recommendation would be to go for the extra power.

I have owned both the Pass 5 and the Pass 3 amplifiers. The 5 is a more refined sounding amplifier. It is not a power issue, but a design issue. The circuit and number of components internally is slightly different. IMO the 5 is well worth the extra $$. Also send a note to Nelson Pass via his website. His description of the differences between the two amplifiers is quite eye opening. The Pass 5 is a classic amp. Good luck.

For existng Proac owners. What speakers would you use for front speakers in a hT setup. Proac 2.5 or 3.8 or Aerial 8's
Thanks
