Raul, an order of magnitude is a factor of 10X. That would be 1000% better. 25% is 40X LESS than that; or 4 orders of magnitude smaller! Of coarse I could be full of it; since I listen to equilizers strung together by nasty, distorting transformers.
Fine tuning Azimuth - Very postive results
I though I would share my experience over the weekend when I finally fined tuned my azimuth on my Basis model 3 tonearm. On my arm the azimuth is adjusted by turning a set screw with a small allen wrench. With just a 1/6th rotation clockwise the results were quite remarkable. I adjusted by listening to some familiar source material each time turning the azimuth set screw in different directions and by different amounts. Finally after about 45 minutes of trial and error I found the setting which was sonically superior and wow the music came alive like never before.
After spending some time last weekend re-listening to many familiar records I had just played a day earlier before the azimuth adjustment the improvement was more than I expected. I suspected there would be better imaging after the adjustment and there was. Instruments were placed more precisely on the sound stage from left to right with greater clarity and precession but what surprised me was the added body and fullness to the music across the whole audio spectrum. The vocals were richer and more fleshed out and the bass had more weight and impact. The feeling I had when listening after the change is my benz LP phono cartridge was digging out more musical information from the grooves of the record resulting in a richer and more musical sound or another way of putting it is my stylus was getting additional musical information that it was not before . In comparison before the azimuth adjustment the sound was thinner and less focused across the whole audio range and the music was somewhat less involving overall. Although it is hard to measure exactly because everything is subjective the improvement with my setup with my Basis 2500 signature table and steelhead phono stage was at least 25% across the board. In some ways I found proper azimuth setup to be as important as proper VTA setup in so far as getting the most information from your record grooves. This tweak had a very positive impact impact on the sound and is highly recommended if you have not already done so.
As a side note I know there are more accurate ways to adjust the azimuth using the wally azimuth tools and my method of listening by trial and error is more crude but never the less the results are postive. I am sure the wally tools will give me even more accurate results but I fell I am so close with my current azimuth setting that the difference would not be great.
Enjoy the music
