    What is this?

    I could post it over at gearslutz on the mastering subforum where perhaps some mastering people who worked with tape recognize the issue or you could post there. If you want me to just say so. I post there now and again.

    What is this?

    Looks like the same effect. Starting the tape maybe the bias wasn't up to frequency and takes a short time to get to the proper frequency. I think all those blips were the same at about .61 seconds. They probably are from edits or punch ins. The bias was operating out of whack and caused...

    What's the best passive (and preferably floorstanding) speaker one can find for $2,500 or less?

    Well I thought near $22k was in the ballpark. I guess underbudget is a deal killer. ;) I must admit Diy at this level didn't occur to me. The design acumen of The $25k speaker designer makes me wonder how many diyers could come close. But there you are.

    The Revel Ultima Salons are in the ballpark. I'd look at Magico too. I'm sure there are others.

    The Old Colony Speaker builder mag had articles for making your own AMTs. Interesting and good results, but never quite the ticket.

    Is it possible to measure phono cartridges like you do DACs?

    You can measure for accuracy. All the normal things. You'll need a test record and otherwise measuring gear with the right loading.

    Bit perfection

    https://wiki.jriver.com/index.php/Audio_Bitdepth Look at the section Bit Perfect on this page. It describes how 64 bit volume control is not a problem. The errors with 64 bit volume processing are so small even 100 million conversions will not change the waveform enough to alter the 24 th bit...

    Closed or semi-open headphones with wide soundstage

    I don't know what they do, but various AKG phones I've used have a wide soundstage. So try the appropriate one or two for your budget. That includes the 701. I've not used the others in your list to compare.

    Please confirm or correct my design "principles"

    Active has some advantages if you are purchasing. And long signal cable is not a problem. What's the budget? And are you building this yourself?

    Do you null each pair out against the reference pair as part of QC? :)

    Everything is better now than then. Well except for sperm counts. https://www.vox.com/science-and-health/2018/9/17/17841518/low-sperm-count-semen-male-fertility

    What is this?

    Well certainly it could be, but I don't think that is what is happening here. The original Epic CD was transferred with Sony 16 bit converters. Yet this artifact is in the oldest CD and in the high resolution remaster. Seems it is likely in the original two track master.

    What is this?

    1990, I remember it well. Some of the memories are good ones too. Of course I was alive when Boston first released their albums before anyone had heard of CD. For what it is worth I still have a car which I purchased the year Boston's Boston was released. I owned the album on 8 track as...
