New rack or power conditioner

The reason I asked about your system was to see if a new rack was the right choice for an upgrade. For example, if you really needed a new pre amp, it would be foolish to put the money somewhere else. Assuming your system is in good order, you really need to look at your components themselves. The type of components, and how well they are made will dictate how bad you need a new rack. Sources with moving parts like TT's and CD players and components that use tubes, tend to benefit the most from a good rack. Also, some components are designed in such a way that they are less prone to vibration. A good example would be my Wadia 861. It sounds the same no matter what you put it on. My Rotel 1072, on the other hand, improved when put on a good rack. Even more so with cones.

All things considered, the best overall approach may be to go with a good quality, but not ultra expensive rack, and then treat each component individually with things like cones and tube dampeners. If you have a TT, you may want to consider a nice base for it. Doing it that way is the best value because it lets you put the money where you need it most.

I buy these types of products from The Cable Company. You pick whatever you want and they send it out to you to try in your system first so you don't waste your money.

Babybear and I were going down the same path...I think room treatments are first investment...bass traps and something at the first reflection points are a must to start...

Although we don't know what you have in your room.

I assume you're pretty handy with wood working..I'd replace the MDF shelves with a hard maple...for not much money...2-3 inches thick. You can then experiment with a few footers like those from still points or symposium...

Also, do you like in a home? Do you have dedicated lines to your BAT equipment? I used to own a BAT VK51SE and a BAT VK P10SE and a BAT VK 75SE..it was all pretty current hungry and responds welll...again for not a lot of money...If you have your BAT in the Tice it maybe restricting the current somewhat....

Just my 2 cents with out knowing more...

I was thinking of changing the mdf to maple or ash, but I am getting kind of tired of the look of the rack ( the alltread). I do have a dedicated line. As for power cond. I am leaning towards the SR Powercells. I just saw a Gregitek rack and have to say it is a nice looking rack but not much in reviews.

As for building a new rack from scratch, the wood would be no problem, but the isolation of the shelves is the biggest hurdle. I guess some of Herbies Audio items would work.

I was going to recommend swapping out the MDF for slate pieces until I read your comment saying you're tired of the look. My rack is similar but with slate shelves. very heavy and solid feel. They pass the knuckle test with no ringing, just a dull thud that can be painful.
Mine is nearly ten years old and I am tired of looking at it but don't want to pay for better performance.
