Check out Fosi amps on Amazon perhaps before automatically dropping more $$$s. Little to lose. I have one in one of my systems and it is a big time overperformer for the price. Drives kef ls50s nicely which is not a particularly easy task and sounds very good. Also have Bel Canto c5i which is a wonderful device as well.
Small form factor integrateds
Going back to looking for a small form factor integrated for a desktop placement of electronics running PC to USB. I know about Rega Brio, Heed Elixir and a used Bel Canto. Anyone ever compared any of these? The Bel Canto is I guess a Class D but reputed to sound excellent and high powered. It could be a multi use am which is why it made this list (plus costs about the same as the others used). Any comments on sound for these? Will be driving Spendor S3/5 on bookshelf in home office playing a wide spectrum of music. Thanks.
