thanks that's quite interesting, i've got another 1364 i can pop into the headphone socket so i might pop that in before the beers and see if i get the same outcome.Originally Posted by rhmjmango
There is quite a big difference in sound signature when using one or two LT1364 opamps. I had a LM4562 in the line socket and a LT1364 in the headphone socket for a couple of days and i noticed that the high frequencies where dominating on my Grado headphones, very detailed, very forward, very dynamic, but for me too much off everything.
I changed the LM4562 for another LT1364 and the sound signature changed completely. Now the low frequencies dominate much more and make the sound more balanced and less fatique. The bass now is really BIG!
I am waiting for the 4032 chip from Tirna how they stand out to this config.
i've given the single 1364 a good 6-7hrs playing time today and some of the forwardness has gone and a bit more bass has developed in the last hour ......was a little bass shy at first compared to the stock opamp (about the only negative) but not much in reality - i could easily live with the 1364 as it stands tbh, definitely lively but not harsh at all for most of my recordings....i think my Arcam amps gell with them nicely.
sounds like the 4032 really stand on top though, mine still aren't with me....but the 1364 is sounding phenomenal, and i can't imagine the 4032 actually improving it lol. - played a wide variety of tunes today Devo (yes Devo rock), Get Well Soon, Hot Chip (sounds unbelievable), INXS, Massive Attack, Black Crowes, Slipknot ....all of it sounds vastly improved and the metal/rock albums have a lot more energy than before.
