Looking for an amp for my Proac 1.5's.


Hi,

I've recently purchased a pair of Proac 1.5's. Great speakers. Currently running an older ADCOM GFA 555 200 w/ch.

Looking to upgrade amp and preamp and looking for suggestions.

Also, a buddy has an old Threshold s150 Class A amp for sale - would that be a good fit?

Those 1.5's are really nice. ProAc's Stewart Tyler supposedly uses tubed Audio Research components.

I'm running a pair of Tablette 2000 sigs with a Threshold FET ten hl & S/350e combo. The top of the line Fet ten, which replaced a Forte F44, really smoothed things out. Flute, soprano sax and grand piano sound musically natural. They were a touch harsh thru the Forte. What's the hang-up with the Adcom?

The Threshold S/150 is a class A/B design rated at 75 watts per channel. When Threshold added optical bias to the S series the entry level S/150 became the S/200 @ 80 watts per channel. The S/200 is deemed class A/AB.

When I was in your spot I called Threshold to ask about their Forte line. The nice guy I talked to said "Look for a used S/300, you should be able to find one. They were quite popular." I took his advice and started with a pre-optical bias S/300. It's the next step up in that line. It kicked butt with floor standing KEF Uni Q's and held its value like a champ. In optical bias form the S/300 retained the 300 designation and the cosmetics changed. Good luck in your search.
