Ok, let's change the question to -
Can anyone make suggestions for a good tube integrated amplifier worthy of consideration for use with my Merlin TSMs?
There is some evidence to suggest that if the integrated uses El34s for output tubes it is likely it will sound good to you, as it does to most users that have used/auditioned/owned Merlin speakers. While subjective, use of this tube seems to appeal to more Merlin listeners than integrateds using KT88/6550s.
