Better power cord for Bryston

I just bought a 4B ST and it sounds just superb w/the stock PC. I bought some used Blue Circle power cords, model 61 and 62, and it made a huge improvement w/the Bryston BP-25 Pre-amp. (The smaller 14ga. used w/the pre.) The larger guage BC 62 I'm using on a B&K ST 1200 which made a huge improvement as well.) I'm tempted to try this cord on the 4B-ST, but honestly, the amp sounds so good I highly doubt it will make that much of a difference. If it does, I'll be late alot more often for work! Anyway, I'm very impressed my these two cords.

If you look through Bryston's website, they don't recommend aftermarket cords for their product, since they designed it, they should know.

If you check the reviews of the 14BSST on the Bryston site you will find that the review sample sent to AIG(?)had a Sunfire pc. I have used Transparent pcs with a 4BST and 14BST and found significant sonic improvements.

I know it's a totally different animal than your 4BSST, but I replaced the stock cord on my B60 with a modest Signal Cable pc. An already quiet amp got quieter and there was a slight increase in dynamics. An upgrade that was definately worth the money.
