. Placebo is a strong medicine. LM4562 = LME49720 = LME49860. There's no reason to believe any of them should be better than the others, but maybe different batches sound different.
Sorry it won't be possible because I have no friends in real life. My method of testing is just extended listening to see if anything changes and switching back and forth to verify. Placebo is a strong medicine, and it can become far more effective than actual medicine once firmly believed in
so in a sense I value my placebo-prone tests to DBT. But if I had friends yeah I'd do DBT
I'm very much impressed by the LME49860's, it gives a very complete and neutral sound but it sounds flat and 2-D compared to the earth hdam. That's my feeling after 15 hours of burn-in. I'll see again how it compares after 50 and 100 hours just to be sure.
I'll take out my sound card and do A/B of lm4562's and lme49860's later, right now I've only compared with my lme49710's, but my memory tells me lm4562's and lme49860's sound similar.
