Yes, I use a Melco S100 and there are others here with the same.
I have to say that I can discover no reason at all why it should make any difference.There has been a lot of discussion here and I have had long conversations with a friend who before retiring ran the network for a national airline. Switches should make no difference ( so long as correctly configured for the purpose). However , irrespective of any logical conclusion, they do. So the question for me is now not do they make a difference but why they do? Incidentally everyone who has reported hands on use here has reported audible differences. It just that one or two found it a negative change compared to what they already used. All the rest have reported a gain in SQ.
