Following our chat today, I put the Linn felt mat back on my LP12 with my brown paper and cork studs on top. Didn't bother to adjust the arm height but the difference was enough for me to do that next. I'll do that before we talk at the weekend.
At the start I thought that things had softened up, especially the drum kit but on playing different lp's I decided that it had to be the recording, Kenny Burrell - A Night At The Vanguard as the rest of the discs I played were anything but soft. Sonny Rollins- The Bridge, Duke Ellington- A Drum Is A Woman, very precise and detailed. More listening is required, possibly the same set up on the 401 . Also I was surprised at the Linn I actually had a sound stage which I've missed for a long time, some fettling is required elsewhere.
As an aside that Hana that I'd used today isn't as advertised, it certainly NOT a mono cartridge, I had instruments spread all over the place, piano hard left, drums and saxophone central and bass overlapping, vocals towards the right. Please don't tell me that it was an illusion and that I'm imagining things, we all know that stereo is an illusion don't we?
