Sounds like another 49990 convert! Hope things keep improving.
Has anyone tried the 2107 opamps with the 827s
That's my current combo in an original EE DAC. Sounding v good to me.
Levi, very very nice, can you add any comparison?
I can't believe it, but the LME49990/827 combo has already won the battle over the oem opamps/Psvane tube. I've been playing everything I could over the last couple of hours, and everything sounds better with the LME49990/827 combo.In comparison, the LME49990/827 combo has more bass definition and more bass impact. The midrange is very similar, but the tube comes off as slightly smoother. I can't pick a clear winner here. The treble is where things get even better. There is a slight shift down in timbre, and the treble comes off as more defined and realistic sounding. It's actually a little richer than the tube sounds. Everything is very clean for both, but between the bass and the treble, the LME49990/827 combo wins. So it looks like I'll be putting the tube away in its box. I finally found something that beats the tube output for me.
Thanks, TJ. Very interesting. I appreciate all the testing, and posting what you've heard. I like the 49990 all around, but I may give the 827s a try.Just to confirm- you're running 49990 in the dual U1/2 positions, and 827 in the single U6/7 ?
TjhubWhat dac are you thinking about getting?
The Burson's completely transformed my previous DAC, a Music Hall 25.2, into something VERY special. I won't sell my DAC until I at least try the Burson's.
