Hey guys, I've had the LD1+ for about 3-4 months now and I have a pair of 6AK5W tubes which cam with it as an upgrade and I also purchased a pair of Voskhod 6J1P-EV tubes which I've listened to for most of the time I've had the amp. I was going to (and still may) purchase the MAD ear+HD but I was reading a thread today where they compared the LD1+, Asgard and the Ear+HD and found that people were changing their op-amps and trying all different types of tubes, so I thought since I have the LD why not try this before jumping into the Ear+HD. I read that a lot of people really like the Burr Brown OPA2107 by Texas Instruments so I ordered one tonight and it will be here soon. I like the way the LD sounds now, but I recently purchased the RS1i's and would like hear some different sound choices with them. I really like crystal clear clarity, crisp highs and detail. Can anyone please give me some advice on some tubes I can purchase for this sound, and that also match well with the RS1i's and the OPA2107, this way I can order them so they will arrive about the same time. I think I should do some experimenting with the LD being that there seems to be so many options for this great little amp, but I really don't where to start, so I figured I'd try a different op-amp to start with.
BTW I probably didn't even let the 6AK5W's burn-in before changing them to the Voshods. I would have to say that I have close to100hrs on these tubes by now and the amp does sound nice to me, but like I said, I want to step it up a bit and possibly hear its full potential especially with the RS1i's.Thank you.
