Clock synchronization issue?

After a lot of experimentation lately I've come to the conclusion that there is a lower mid-range/upper bass frequency dip when using my Simaudio 650D with my Sooloos MC200. This dip doesn't occur with the other DACs I tried with the Sooloos nor does it occur on cd play through the 650D. My Sooloos dealer thinks it may be a clock synchro nation issue between the two units and is thinking that inserting some sort of re-clocking device between the two units may resolve the issue. Any thoughts or similar experiences you could share to help me out?

FYI, the Sooloos up samples the digital signal to 88.2 kHz and applies an apodising filter before outputting the digital signal. I'm not sure if the 650D also uses some sort of up sampling as well.

Audioengr,

Your company has continued to advance with some great new products...congrats! I remember reading you wrote that NOS DACs can sometimes have poor jitter rejection...if i have an older NOS DAC (Zanden 5000 Signature)...is there anyway still to take one of these servers...such as the Sooloos...and: 1) relock 2) add an i2s output to be configured to go into the Zanden i2s input which i have heard is by far the best way to use this DAC?

I believe your company used to do this. Thanks for any advice!

Steve N.

thank you! Good to know...I have a 2nd hand Valhalla digital BNC cable...does this work for you?

Meanwhile, i may contact you about Synchro-Mesh (presume this is one of your products). Any chance for a reasonable sum, you could have it customized for i2s output to my Zanden?

Thank you!

Hi Steve N,

thank you...I was using Cardas Neutral Ref...was surprised to find i did not like the trial Transp Ref which i use in the rest of my system...and this one-off Valhalla 2nd hand was available and it worked much better...

In any event, the Zanden uses a computer cable linkup for its i2s...as i am told, one needs to know how they configured the link so it could be compatible with the source.

Hi Steve,

I really appreciate your time. I know you're busy running a business. The Zanden uses a computer cable which looks like the ones used in networking at the office...like a phone jack with more wires...8 i think.

Interesting! That is quite cool! I have done some reading on the Off-Ramp 5 from the site and reviews...i think it is computer audio only?
