Dear @mijostyn : " I’m sorry Mike but your Studers are a poor reference. "
Well, it’s a reference till some levels depending what you want to test/compare and with what purpose.
There are several problems with R2R units , one of the more significative is that in the past all audiophiles took as an audio reference the R2R to compare its quality level performance against other sources mainly analog but even digital too
Yes, live MUSIC is the main reference and nothing can changes about but I can tell you that through my audio life other than live MUSIC I changed my comparison home system reference that I take as part of tests proccess.
I followed @mikelavigne system and opinion for many years and he are really in focus because he almost always posted that the Studer A820.........exactly as in this thread he posted that twice. So he is sticking with that reference. Mike the following information is with all my respect to you as always and in NO single way I’m trying to dimish you or those beautiful Studer 820 but facts are just that facts.
For me and from some years now other than live MUSIC digital alternative is untouchable by any R2R tape or other analog source no matter what. I posted about at least time times in the last 10 years and the latest MoFi controversy only confirms it.
That gentlemans as Mike still does not accepted that ( even that are extremely happy with the one step MoFi digital Lps and they know came from DSD master. ) is a " problem " for all them: we can’t live in the past. Everything is in movement and changing and I think we have at least try to learn about.
Look, these are some specs of the Studer A820 that confirms in some ways what you posted and I said here:
- tape speed deviation: +,- 0.2% - tape slip: +,- 01% . Speed stability here is even more critical issue than in a TT because is the recorder and the information used to cut the LPs.
W&F is +,- 0.03 % at 30" and 0.04% at 15" speeds.
Frequency response +,- 2db ( that’s a swing of 4dbs ! ! ) at 30ips from 40hz to 22khz and at 15ips 30hz-20khz ( really limited frequency response. ) and obviously that at +,- 1db deviation FR is even worst.
All those are facts and those facts tell me that can’t be my reference against my today digital reference and I have to say that I’m an analog audiophile but mainly a MUSIC lover and I like to have almost always my foots in the ground. Audio " dreams " are not any more for me.
No, I’m not against Mike ( or any one else. ) and he knows it. I appreciated him.
