I had another source on CDR to LL143. Same recording and original source, different transfer however.
It was a little lower in volume, but the hiss level was also. Speeds were the same. Overall sound seemed about the same.
There was some tiny difference in content, notably a point in the second Walkin', which I have inserted in, more akin to LL143, with volume reduced accordingly. Removed a few pops and gently EQ'd to bring a bit of life to it, but nothing extraordinary.
