If you can get it "off the ground" I would be willing to pay a reasonable fee for auditioning ICs and cables. Why not also add power cords-- much audiophile interest in these.
However, the posters above provide some food for thought re actually getting such a venture started. The last time I got wires from the Cable Co. (3-4 years ago), they were charging a percentage fee to audition wires with the fee(s)to be applied against purchase. If you didn't purchase though, the rental fee was effectively fairly high,in the 5-10% of MSRP range. So it was only a good deal if you actually planned to purchase-- which I did.
Good Luck. Craig
