I own a Bryston 4B-SST2 amplifier and have it via Pangea '9' from my Furman REF 20i conditioner.
I find the sound is very slightly warmer (good) and smoother (good) and clearer (good) with the Furman.
So I use it.
I decided to buy the (used) big top of the line Furman because i tried a smaller Furman on my Denon 4806 Receiver and was very pleased, even though I returned the cheaper Furman because IMO it was (retail) very overpriced for what it had inside. So I found a BIG Furman ($3,500 retail) and got it for a good price ($1,400) and could pick it up. great!
I use the Furman for the non-digital (pre/amp/Plasma TV/Receiver) and the Monster for all digital stuff.
Prior I had a Forte' 4a amp and alternated plugging it 'in' or 'not in' the Monster 7000SS conditioner I owned (and still use for digital). The Forte sound was a trade off with cleaner purer sound bur LESS bass and a leaner sound with it on conditioner, and better bass but a veil over the sound off the Monster.
Once I aquired a Pangea 9 power cord I used the MOnster as the Pangea restored the bass even though the amp was on the Monster conditioner!!
So I use the Pangea power cord still, on the connection from Furman REF 20i to the Bryston 4B-SST2
So the best course it to try it and listen for yourself!!
Any commnet is only a review of someone elses listening experience.
The 'old saw' about amp straight from wall is best is just OLD 'common knowledge' and not always actually valid for modern or good power conditioners.
The golden rule is:
TRUST YOUR OWN EARS.
