I installed a set of Mundorf silver and Oils into a pair of Dodd monoblocks for a fellow audiophile. I know he likes a lush sound, but the cap choice was his. He was initially impressed with the sound and the detail and the transparency, but found that he grew tired of it after 6 months and sold his Dodd's.
So transparency and detail are not for everyone. If you're looking for lush then get something that is definitely lush, like PIO's. If you want transparency and detail and texture, then the SIO's and teflons are the way to go IMO.
