I dont know anything about the DSP and which is better. If $3 will get you the best one, then why not use it? But some of the opamp used are little better than quieter 741's. There is no excuse for that at all.

I have a new Benchmark ADC gathering dust from the CD experiment …. use the TOSLINK or USB from it to miniDSP?
-RNM
When I use the term MidFi, I mean grade C or average. There certainly is grade B and A. Even an occasional A+.

Different use case to the one I was proposing. For ripping vinyl the noise floor is laughably high compared so any SRC grot so I personally wouldn't worry.
I can't hear the brownian motion of air molecules in my room so it really doesn't bother me except for a bit of specmanship. As you haven't heard the part in question claiming its midfi seems jumping to a conclusion?
It would depend on what you want to do with the ADC and what software and drivers are on the computer, etc. I still find it can get complicated sometimes, depending.
Commercial recording I can buy that has that?
Mark listens very quietly with speakers that can't take much power. That was my point. 90dBA (you told me off for a lower case 'a' in the past) is waay to loud for me as a ref level. I did get -20dBFS as the ref point for the 65dBA which I hoped would prevent handwavingly inapplicable comparisons with the second violins at the Boston symphony 😛.
Just use it in place of the miniDSP's ADC. On more consideration, I will use its' USB. I will use the Sony HAP-Z1 as primary source (Not TT nor CD) which has wave files stored from HD (uncompressed) files downloaded direct from Masters.

Then go in with SPDIF. Depending on miniDSP you may or may not be able to make the ADC the clock source. If you can, probably better to do it. If not, then don't worry about it.
Beside your point is that Mark listens in near field (close to speakers). The cone displacement is very much lower this way and lower listening level also aids in reduced listening fatigue. This minimizes the spkr distortion and also suppresses the room influence . All together, it is much easier to detect any differences.
Under those conditions, the only down side is detecting differences in the bass. Higher spl is needed here for the obvious reason.

I'll try to find my copies. They were a regional "Audiophile" CD company doing classical music. They were quite proud of their line, didn't impress me.
Ed, why do you think they can? The die pulling argument does not cut it. More importantly what do you mean by directional?

I seem to be confused. I thought you wanted to use Benchmark ADC as a source for miniDSP? The ADC must have SPDIF out, so what am I missing?
I have some Reference Recordings CD's that are unlistenable and IIRC were not even close to 30dB crest factor. One needs some care BTW in specifying crest factor with respect to BW and averaging.

the only time I know of that cable has directionality is when only one end has its shield tied to common/grnd and other end is floating its shield. It is fairly common in some audio cables to do that.

That was already covered, I'm talking wire as in the magic BT silver hookup wire.
Where is THAT? Magic silver BT hook up wire. Why read and get upset about that stuff. Its like Fox entertainment news. Too much is fake info. In Asia all real info is allowed. Chinese, Russian, Japanese, Arab etc but not Fox "news".
Not that silver isnt different from copper plated steel wire. But directionality could only come from crystal structure is in one direction/asymmetrical.

Scott,
CABLES are not wires. Most of the effect comes from the connectors. If you do not use a cleaner like Deoxit on them there is a very clear difference in my measurement gizmo when you turn them around. Even when treated there can still be a bit of effect particularly on thicker gauge center conductor cables.
As to measurement levels dBa spl has a reasonably well defined meaning down to meter ballistics. There is a bit more difference among the meters on peak level.
