Up & Over sampling Is one superior to the other?


I see many contrasting ideas on up sampling, and over sampling. I want to get a DAC quite soon and have gotten the impression from reading reviews, that up sampling is a more forward presentation and can be analytical.... over sampling is more resolving and refined, yet laid back sounding.

Have I the wrong thoughts here? or is therre any truth to those diffs?

Do tubes really make significant diffs over strickly solid state (given all else is resonably the same)?

I thought to try making sure before taking the plunge.

I am most grateful for any help here from those who have had both or either...

SRC is Secret Rabbit Code, written by a coder in Australia. It is a plug-in for Foobar2000. Foobar2000 is a free player for computer, the best-sounding of the PC players IMO.

I posted recommendations for the best software combination on my forum, based on feedback from customers and my own listening tests:

Thanks, Steve

Anyone had compatibility issues with that Foobar 2K software... it's not confidence inspiring reading through their FAQ's.

I also didn't see where it did Apple lossless, I've nearly everything in AAC & AL. yet I'm likely gonna re-rip onto a big NAS drive soon... just hate to relearn another software, especially if it's clunky, or PC knowledge based intensive... though I know more than a little... I ain't the PC genius I think i am most often.

Steve, looking at your subjective ranking for the MSB Gold Link w/Power Base in regards to both upsampling selection and also sound in general, you might be interested to check out my archived thread.
Blindjim, I would suggest you take a look at my thread entitled: Reference DACS: An over all perspective, it contains tons of information on non/up/over sampling, solid state/tube DACS on the market today.

The discussion revolves around to distinct types of "flavors" in world class DACS that are described as Type 1 ot Type 11.

There is no one "superior" approach to the D/A conversion process, but personnal taste and system synergy really make the difference. Look at the thread for fine details in the sonic differences.
