The main thing to look for is an amp with a friendly input impedance, since the main tradeoff with the 17ls is its output impedance. This is especially true if you are using long ICs and/or high capacitance cables.
The McCormack suggestion is good (same as what I use with my 17ls) and it should run much cooler than your Aleph. If you like tubes, I'd save up for the CJ premier 140. Your vinyl setup and speakers are impressive and probably deserve the Premier line of amplification.
