Stuart, The line level outputs from an SB are sufficient to drive an AMP3 happily. The AMP3 has a single stereo input, so if you want to change sources without unplugging then a passive selector or preamp will be required.
If you use volume control on the SB then all you need is the AMP3, PSU and some speakers. If you are feeding the AMP3 from a DAC and have the SB set to max (for best quality) then you will need some form of volume control before the AMP3, you can easily wire in a quality stereo potentiometer to do this. The basic AMP3 gain is either set by the input resistors and is fixed when you build it. I am using the AMP3 with an SB1 at the moment and I think the default gain setting for the AMP3 I set at build is maybe a bit too high (certainly for internet radio, but not for classical cds ripped to FLAC). I hope to receive my SB2 this week and will test this as well to select the gain before I build my next AMP3. Total cost - AMP3 £23 inc postage, PSU £15 (could be upgraded), Basic Case & HW - say £15, about 6 hours effort for first assembly (will get lots faster), and very tired hands from winding toroids. I think this is brilliant deal for the quality, but the little TEACs do look much prettier and save fiddling.
