Hi guys, is anybody know why my speaker B&W 685 sounds a whole lot better than my MA GS20 ( my concern is the GS20 cost 3x more expensive than BW685 ). I hooked them up with my Roksan Kandy L.III Mk.III ( integrated amplifier) and Arcam DV79 ( cd player ) and I used QED Silver Spiral for analog connection and I used Analysis Plus Oval 12 bi-wire for speaker connection. After I tested them with B&W685 and MA GS20, I'm very surprised because the BW685 sound is very good, very smooth, very natural and the treble is very nice to hear meanwhile the GS20, oh man... !!! the treble is too bright, the sound is not very smooth not natural, I don't understand I paid the GS20 3x more expensive than BW685, but the result is very very bad...
Is this because of my Roksan Kandy ??? or my Arcam DV79?
Can somebody help? If it is because of my Roksan kandy, what integrated amplifier is the best matched with my GS20?

Thank you guys in advance.....
