Audio Research LS-15 Infincaps

Warnerwh thanks. I did think of that before and decided against it. Your suggestion, though, is not an answer to my question. But thanks anyway.

I think I neded to be more clear in my original post, but I will clarify this a bit now. I don't want to sell my LS-15 and replace it with something else. All I would like to hear is if someone had compared the one with infinicaps to the one with REL caps. What is your opinion. What did you think was different. Worth sending for upgrade and be left without music for 3 weeks? Or live with REL caps and not bother with infincaps. Thanks.

I assume the upgrade had noticable impact? Resolution, bass... Where is the most change in the way it sounds now? Could you please xpand on it a little?
Thanks a lot.

I ended up installing the new TRT Dynamicaps instead of the Infinicaps I planned to install. So far I have about 15 hours on the new caps and they are improving with every hour of use. Big improvement in the bass region, cleaner overall presentation. Sounds more natural now with better dynamics. I'm beginning to get used to the new sound and I like it. I think the sound will improve further with more hours/listenning time on the new capacitors.

Thanks gents! I do like my LS-15 a lot, have it for long time and I am the original owner. I just heard that infincaps take this already fine sounding pre-amp a little further up sonically. That's the reason I was looking into upgrading it with infincaps. I will send it out for an upgrade now for sure. It doesn't cost that much and besides, I have no plans to sell it in a near future. I like its open sound and good soundstaging, imaging and overall reliability. Thanks again, but keep it coming if anyone has other suggestions for LS-15 upgrades.

Agree...those sovtek 6922 tubes that come with the LS-15 are not worth the effort. I did replace them with nos Amperex EC88 it is much smoother now. what is ei 6dj8? what brand is that?

Thanks. This is what I am talking about!!! Great suggestions. As I said before, I really like my LS-15 and just looking to improve the way it sounds. Selling it and getting something better is certainly an option in the future, when I really get sick of the pre-amp, but for now, I had it since 1999, bought it new, and still not tired of it. As for the tubes, I saw tubedepot on the web before, just dodn't know how reliable those guys are. Is it safe to buy tubes from them? I may check out these EI tubes. Thanks all.

LS-15 production with infincaps I think started on or around `'99 - '00. Also, along with infinicaps, ARC started making LS-15 with detachable power cord. Not being a big fan of replacement power cords, I don't care about that particular change
