The winters lessons.

I think it's time to move on from this past weeks discussions to something new. This past 5 months I've tried out a number of different footers, shelves, tweaks, power cords and conditioners. I'd like to share what I've learned here and hope others will do the same. Due to the unreasonable length of this thread I've broken it into three posts, Footers and shelves, power cords and conditioners and tweaks. That way you only need to muddle through my rambling if they interest you. My basic set-up has not changed this year, SCD-1,Kora pre-amp, Aloia amp and Audio Tekne interconnects (and my Empire turntable, clearly not a major component here). I started trying different footers but I went in a bit different direction that Redkiwi. I have been trying a number of Black Diamond Racing products since using a series of cheap cones and have found through a lot of trial and error a good match for my system. I also bought two sets of (OB) Orchard Bay cones, one titanium and one brass. These became the building blocks for me. As a lot of you know, and some don't like, I have a sandstone slab on a masonry hearth so my base is solid and in effect ground. For Christmas I got some BDR pucks, Cardas caps and these "vibration sheets" sold at Music Direct. As a summary of the following posts I would rate the value of the below items in the following order. 1- BMI power cords, 2- P300 power conditioner, 3- Neuance shelf, BDR puck, 4- Quiteline filters, 5- Monster HTS-2000, 6- dedicated circuit. For the rest you'll have to judge for yourself after reading this. If anyone has particular questions feel free to post or send me an e-mail. I tried to keep notes so I could tell you more, GOD FORBID!

1st Update on winter lessons' lessons. I managed to locate certain vibration points using Jadem6's water trick (thanks again!). Placing cones accordingly, I gained treble energy and clarity using cones on the power supplies (CD and pre) rather than the machines. Putting cones undet the CD and pre, *shifted* the frequency response upward, giving too much treble at the expense of bass. A friend suggested I use absorbant material as a weight... sand bags etc being out the WAF region, I tried large, thick books (6-7 pounds), placed over the vibration points on: the CD, better imaging, tighter focus; the pre, more neutral sound, no loss of detail throughout the audible spectrum.
Maybe metal weights give their own *flavour* to the system -- i.e emphasizing treble??
On the down side, books on a piece of equipment look a bit silly....
BTW, JD, one cone under the power supplies, placed as per your findings, still sound better than three in my system!

Thank-you for the update Greg. I tried the single cone centered under the wire coil with no other cones. I ended up with it moved off center about 1/4". I think it's almost identical to my previose set--up except for maybe adding a bit more colour. I used Dave's True Story "Sex Without Bodies" song #5 as my test. Without wieght on top the bass was less detailed and a bit softer and the treble was without definition. I found weight with a single cone made Kelly Flint's voice smooth (don't tell my wife but I love Kelly)with good foundation.Bass was well defined, not the best but 95% there. At about 1 minute into this track there is a light either metal on cymbal or brushing of chimes in the left rear middle. The definition was best with cone centered, but the overall presentation was too bright. I'm going to stick with the single cone weighted for a while, I'll let you know the final. I find it just increadable that these tinny movements can change the quality of sound so much.
As per your books, I think that if Redkiwi were here to help us he might think the books add too much mass (slowing pace and storing energy). It might be worth trying the books seperated by cones. Who knows, it's fun trying this stuff though. J.D.

Hey Jd you mentioned where to get brass weights. I would try a jewelery supply,
I nominate JD for best thread, excellent.
