Between L2 and L10 it would be L10. Some points to consider:
1. It is serviced or restored. At this price, L10 better be restored or at least recapped. Otherwise, IMHO it is not worth that much as a restoration will COST you.
2. It has 2 DML ICs which do go bad. The originals are not available but there are 3rd party substitutes but those cost around 80 GBP. Does the L10 have the 2nd gen of DML of Luxman (which do not fail) or the substitutes. If the DML are original ones then do consider the cost of replacement.
3. The output transistors are sanken which are responsible for the famous sound of L10 but are now unobtanium. It will work with substitutes but that sound is lost. For me, this aspect is a deal breaker as in the absence of appropriate subtitute outputs, I cannot future proof an amplifier.
Hope it helps you in taking an informed decision.
Edit : Just saw your new post. As prem said, L10 but ...... as I said above.
