So I finally got my LPS-1 in the other day and realized it wouldn’t work without an adapter to their stock jack. For some unknown reason PS Audio uses a 4.75 x 1.75 mm jack for the LR, which is very unusual, and necessitates an adapter to fit to the much more common 5.5 x 2.1 mm jack. It’s even more curious since the ICRON unit the LR is based on uses a 5.5 x 2.1 mm jack. Whatever. So I ordered this adapter set from Powerstream that has multiple different sized adapters, including the 4.75 x 1.75 mm, based on Alex from Uptone Audio’s recommendations.
After I bought it I found another single one here I think would also work:
Anyway, I finally got the adapter in today and plugged it in to the stock LPS-1 jack and powered up the LR and and then gave a listen for a couple of hours using my standard reference material. I must say I think it improves my overall sound. It’s hard to articulate, but everything sounds a little more crisp, maybe with better instrument separation. I dunno. I’m going to let it burn in a little bit to see if it changes. Maybe what I’m hearing is a lowering of the noise floor that people talk about. The noise floor of my system is pretty low already to my ears so it’s hard for me to say that, honestly. Another confounding variable is that I recently changed the fuse in my Directstream and I’m getting used to the new sound from that change (amazing!). For sure everything is sounding better than it ever has with the fuse and the LPS-1 powering LANRover. Once it’s broken in for a bit, I’ll report back with a more scientific a:b comparison.
