Well either that or he was assassinated to keep him quiet?
Haha oops! The OP is back, thankfully not assasinated... most certainly not ungrateful for the advice received... and happy to report that I have not been tied up with blue belts, kidnapped by Linn, or admonished into submission by the dealer! (Oranges & Lemons are very friendly, knowledgeable and helpful and not at all frightening I am pleased to report!) I must apologise for the delay in coming back with an update though... it has been a very, very long time and there are many reasons. I didn't plan for it to be this long, particularly as so many people have been so helpful... the very least I can do is update you on this mini saga!
First of all life happened - I run two little businesses, and people in my life like me to help them with
lots of things. And I've been ill unfortunately (perhaps problems with the LP12 will send me to an early grave?), so time has been very scarce sadly, and even listening to records has had to take a bit of a back seat.
Secondly, I got pretty overwhelmed with the potential routes to fix the issue but elected in the first instance to switch back to the original bearing and subchassis to see what that did. It didn't fix the problem but I did notice a difference - I would say that it warmed up / softened the definition and clarity of the lower end... perhaps this is the 'bloom' that was mentioned by some.
Thirdly, and this is where it might get a bit embarrassing... it became clear there is something wrong with my hearing. Typically my hearing has been above average - yet suddenly there is a bit of tinnitus, a feeling of fullness and some things are more muffled than before. I became convinced my ears were full of wax (as this has happened before) so dutifully followed instructions to use Earol (measured doses of olive oil) before attending to have it sucked out with a little machine. I was alarmed when they only found a little bit in one ear... and even more alarmed to discover that I was now occasionally getting distortion in my left ear, particularly in restaurants / pubs and sometimes just from speech. After lots of research and discussion with doctors, its possible there's something up with my Eustachian tubes. Either a partial blockage, inflammation, or I wonder if some of the olive oil has got in there. SUCH a nuisance and so ridiculous if there was nothing wrong with the setup of the LP12 at all, but that it just coincided with my hearing going a bit funny. I expect to be laughed out of the forum if so!
Anyway, currently I am in no position to properly evaluate the sound. Although I can still tell when there are differences, I can't properly analyse anything. It's deeply concerning, not only because I love listening to music so much but also because I work with audio a lot in my film work... and I'm a musician. So I have an appointment with the audiologist, steroids for my Eustachian tubes and I've put my car under close scrutiny... it may be up for sale soon, as its a bit racy and has a rather throaty exhaust. I want to preserve my hearing over everything else, so perhaps its time to go electric.
Thanks as ever for everyones advice... I'm sure I'll be back with further updates on this thread, because it's far from over. It's just taken a very odd and unexpected turn! I am looking forward to your recommendations for upgrades to my Eustachian tubes, and observing heated debate as to whether I have used the right oil in my ears etc
Perhaps some of you are doctors, audiologists, ENT specialists... I hope so!
