Let’s Clean a Record on YouTube has several reviews of LAST Factory products.
Review of Last Record Preservative – a long review of LAST Record Preservative.
Excerpt:
“My mind’s been blown. The ridiculous extent that we went to, to clean this record and to try to eliminate any variables so that we could really determine if the LAST treatment makes any difference, um… I wasn’t expecting it. I was not expecting to hear much of a difference at all, but boy that wasn’t the case. Absolutely there is a difference and it was so shockingly different I said I don’t know, maybe I did something wrong. So we actually cleaned a few more. …Immediately I heard what I was hearing with the Mingus. Ditto for the Yes album, and especially true for this one (Debussy Seong-Jin Cho). This really drove it home for me. Really understood what differences that I was hearing, and I admit at first I wondered – is there some softening of the initial transient attack, you know, like a pluck on a guitar string?
A Better Sound
At first I thought it sounds a bit softer and I wondered if that’s what I was hearing. But I soon became apparent that what I was really hearing was a better separation of the notes, and it was particularly evident with the flourishes of notes played on the piano on this record. It separated those notes far more clearly. It was not only evident when you closed your eyes and listen critically in the dark – you could be in the next room and it was just clear as day that this was a superior sound. It’s better, guys. I know some of you don’t believe that. I’ve seen lots of arguments online back and forth about whether last treatment improves the sound or not, but I got to tell you on every one of these records, for me, for our ears in this room, it absolutely improved it, and, it wasn’t subtle, wasn’t subtle at all.
A Clearer Sound
I would also say that the images within the sound stage were clearer – they were more precisely presented – not so much that it became overly hi-fi, where you get those laser sharp images, it was still very natural sounding, but the biggest improvement was clarity of the various frequencies that were being played. That’s the best way I can put it. And, uh, I really liked it, so, I did not expect to, frankly. I thought, we cleaned these records so well, that’s the best sound that you’re going to get, and it just wasn’t the case. So I am a fan of LAST. I will be acquiring their largest container because it’s not inexpensive. I think if you get the biggest quantity, based on the number of record size that you get out of an ounce of LAST, probably paying around 60 cents a record. That’s my estimate. I think it’s worth it. So.. yeah. Wow. I’m absolutely blown away by this. I did not expect to come to this conclusion, but, there you are and that’s what my ears told me.”
