Mmm . . . made a few changes recently, biggest was the inclusion of an 'ISOmat' a 3mm, acrylic platter mat, a brilliant twenty quids worth.
A downer was going deaf, I get realy grumpy . . . :wall: all OK now. So I have spent the past few days catching up, its amazing how much I have missed because of the creeping deafness. Been fitting listening sessions into the snooker schedule on the TV red button.
Also tracking down and purchasing the various small bits needed to produce my DIY vinyl vacuum cleaning machine . . . thats all ready now to start assembly.
I've had occasion to move my TT and isolation board . . . listening yesterday was not good, the detail was there but the soundstage was a mess??? One was agitated last night on the Horlicks hour. Whilst Hazel listened, I thought . . . whats going on, why? The problem was easily solved, but not obvious in detection. The P5 sits on 3 feet, triangle style, the DIY asymmetric, broken bell, isolation board, sits on three adjustable, inverted wood spikes, also home-made. The pattern is the reverse of the TT, ie., two feet at the front of the TT, the board sits one spike at the front, feet and spikes straddle each other.
The single front spike was not in the same position as previous, perhaps a couple of cm's to the right . . . nah, surly not???? . . . that 2cm made all the difference in the world, sound stage back to full width, depth and height. There is even a small improvement in definition in the delicate parts, most noticeable on Miserere, in the distant balcony parts, the individual voices are so well defined.
Another late night listen ensued . . . enjoying some Carol Kidd, Jazz at the Pawnshop, Miserere, Gershwin, one of the beauties of being retired, time has little relevance? . . . unless there is an early Doctors or Hospital appointment, how life changes as one gets older, you have to run your life according to the NHS!
So if you have isolation boards supporting your hifi equipment . . . maybe? . . . a re assessment of the position of the supporting feet might be in order . . . it certainly will not cost anything? I remember when I first did the boards, I tried four metal spikes, three metal spikes mirroring the TT feet, the best was three as a revere image and finally swap the metal spikes for wood/metal hybrid. Critical spike positioning is a new concept for me but logical when thinking about the harmonics in the board?
