Please explain in more detail in what way that you feel that Diffmaker is broken and what means you have used to come to that conclusion. But it really doesn't matter. There are dedicated hardware signal processing/measuring devices available, which for instance can subtract signals. While Diffmaker is free, these are not, so not that many hobbyists have one of those. But any self-respecting company that designs, constructs, manufactures and sells audio hardware has at least one. jkeny wrote: > Anybody who genuinely wants to evaluate the Regen has two approaches > open to them - listening & measuring - not mutually exclusive.

Measurements are actually not just an academic exercise. They can be made by any person with adequate equipment and a smidge of knowledge. Good equipment might nowadays still be expensive, but not very expensive. The measurements then form the basis for consumer information. Nothing academic about that. jkeny wrote: > Anyway, there is no such thing as a complete "null" so what "null" do > you think is below audibility?

A null in this case would mean to be indistinguishable from the noise floor of the measuring device, which of course must be good enough. Regarding good enough, I don't believe I have ever seen a serious study which concludes that -120dB is a problem in itself. But anyway, nowadays audio devices can from a scientific standpoint be made better than what humans can hear and good equipment is often just that. And good equipment is not equal to expensive equipment in this sense. jkeny wrote: > Well, you could borrow/buy & listen, as I said before (but this got > sidetracked into a DBT isssue) I would never even consider buying an audio device that the manufacturer claims is making a change and nobody has verified by conducting and publishing measurements for, so I could study them myself. There might or there might not be a difference that exists, is big enough to notice and/or is beneficial. Borrowing it would just be a waste of time for me, unless I or someone I know could and had the time to measure it. But I hope someone else borrows it and measures it. :-) Best Regards, Gandhi not often enough well recorded and mastered cds *|* dbpoweramp with accuraterip *|* flac *|* fanless asrock z77e-itx intel i5-3570t *|* ubuntu 12.04.1 lts 32-bit *|* lms 7.8.0 *|* brutefirdrc 3.0 (rewv5) *|* transporter (balanced out) *|* thule ia252b *|* audio physic scorpio *|* no fancy cables. *+* also some booms. *+* harmony 525s for them all, including waking the server from s3. ------------------------------------------------------------------------ Gandhi's Profile: http://forums.slimdevices.com/member.php?userid=58909 View this thread: http://forums.slimdevices.com/showthread.php?t=103842 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
