I have 2 Benchmark AHB2 (12 inches wide) and a Topping pre90 and Topping D90se stuffed into an IKEA toy shelf. I use this system because it has as tiny form factor, it is super neutral, and sounds good. The Spendor's I have heard in the past were a little warm so I think this gear would sound good with it.
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.
