Help with Meridian 518

Please share how you use the 518 to optimize your stereo system.

I recently added 518 to my system in place of my preamp. The 518 lets me connect my dac to my amp directly. This resulted in a much smoother and transparent sound. However, there are other functions on the 518 that are not used optimally.

I fudged around with the Emph/Deemph, different noise shaping algorithms, and the input/outbut bits, but they all sound the same to me on my system. I know for a fact they do alter the sound, for an old client had one, and he transported steisand into his living room with a mere touch of a button.

My setup:
Cal Audio Delta-Meridian 518-Cal Audio Sigma-Aragon 8002-Kef 103/4
Argent speaker cable, Emerald between amp and dac, and mapleshade between trans/518/dac

Thanks ahead of time.

Reading the manual for the 518 can be a bit confusing at first and you need to go through it several times to start to get a handle on all the functions

We have some basic set up info posted at http://vantageaudio.com/info/518.htm

We use a 518 every day and can give you more info (especially regarding the noise shape settings, etc) if you email directly (it would take too long to post here). Hope this helps..???

Hi, when I had my 518 (with Meridian 500 transport and 563 DAC), I matched the output bits to my DAC (24) and found Shapes A and E to sound the best for my tastes. I found each shape had a different sound, and sometimes the recording I was playing sounded better with a different shape. You can really drive yourself crazy with this piece, but I absolutely loved it and settled on Shape A for most of my listening.

Thanks for your inputs!!

However, I am still not getting any difference in sound quality when fumbling between the different bits and shapes.

Does it matter whether I am using the 518 as a preamp, thus I am using the gain stage with emph? Or do I have to bypass the dsp?

So far, I am using Emph, with sound shape E, and 16bit in, 18 bit out.
