I can't respond with a magic solution for you, but the JMA's are characterized as "warm yet detailed" - I'd stick with 'em for awhile. We don't know anything about your listening habits, eqmpt, etc. - if your post was on a new Facebook thread, you'd certainly get ~100 suggestions. This thread...

I just got my a2m yesterday, and it does, indeed, make my HE6se's very happy! After tasking it for only an hour, or so, I'm pretty "WOW". However, I immediately ran into a lurking deal-breaker: volume control. I switch from FM to Qobuz to France Musique to my music library, and the jumps in...

Thanks - just checked that huge thread: some really good poop in there, but it's also a bit of a cluster.

Thanks for the tips, Dramlin & Dixter. I've only ever fiddled with ~15 selectable chips, including a V6, but my ear always seems to prefer the damned 5532, and the NJM I found on is a sweetie - it presents everything just as honest as I think it can be. I've been a Beyer/Quart man for many...

Wild question for y'all: I just plugged an LM4562 into the little powerhouse amp feeding my V2, and VOILA ! It sounds terrific, primarily because I don't need to EQ the 2K trough !! Unfortunately, I'm now missing key HF elements I enjoy from my standby NJM5532DD. I wonder if any on this...

I just thought I'd update my own chip-swap results to date: tried a Burson Vivid V6, LM4562NA, and a fresh NJM5532DD. Burson will be liked by many, with much body and detail; 4562 "almost" made it, but was lacking just a bit in HF & openness; for the time being, the 5532 remains in the socket...

HEY ! Missed your earlier post - ya, Pros ruled stateside in Seventies, for sure. Essentially weren't challenged here until the HD414 weaseled its way into our market. And the Pros were indestructible, to boot.

Were YOU mfg'd or released in '52, or do you have a CAN mfg'd or released in '52 ? I guess there could be a running 9-month technicality sewn in somewhere . . . .

You, or your cans ???

oooooh, that could constitute a litany of impression, but you asked. In a nutshell, I've spent time with Beyers since the Seventies, and currently have an '81 880 600Ω'er and a now-broken-in-I-think 2021 880 600Ω'er. In a further nutshell: the 2021 is noticeably darker, will never be mistaken...

Let's see: are you as old as my '81 600Ω'ers ?

I have V20, V30, V40 and "had" a V50, which sounded so bad I returned it. My V20 is best sounding, but I use it exclusively as a music player. I'll come right out and probably recommend popping for a new V60, as older phones no longer get any kind of system updates and the apk market...

I only say that because failure of the earbud jack is one of the most common physical reasons cell phones are replaced - just down the list from busted screens & waterlogging. My V20 is a dedicated music player, so the cord that connects to my amp often stays plugged in & unstressed for weeks...
