Martin, since sending the preceding post I have got an education (further) on SUT, a must read for anyone who wants to learn more! I shall email Bob and give him details of my cartridge etc., also my pre-amp and then go with his suggestions... Bob looks like he has had alot of positive feedback, can't ask more than that. Luckily I have a set of MM inputs for my Avondale modded NAC72 thus saving me the expense of a MM head amp. Should be interesting with what Bob comes back with.
