Hi,
The SP-15 is one of my favourite pre-amps. Compared to other pre-amps, there's a lack of colouration and the phonostage is awesome. The SP-10 and 11 are coloured pre-amps, just like the 'nice' Conrad-Johnson Premier 3 was. Maintenance-wise the SP-10 is a bad choice (too many tubes and excess heat). Comparisons with the LS-series amps are nonsense, since these were made (much) later.
You should combine the SP-15 with a decent solid state power amp and good speakers, such as Quads '63 on very high stands and of course a decent source, such as a Goldmund or similar turntable. Then you're in for a sensation, voices are splendid. Do not connect mid-fi, you will surely be disappointed.
I will probably buy a good set myself someday to 'relive' the old memories.
