What problems? EAC can usually run at 8 to 10X in ripping even a bad CD, filling up a FIFO so that there is no possibility of either under or overflow in several hours is trivial and the memory costs nothing. How much can clocks vary and have the recording still be worthwhile fussing over? At CD rates 1% off is not even 7M bytes an hour. I found the IEC consumer spec 1000ppm or 0.1%
EDIT - We crossed, at 1000ppm max it is trivial to buffer even 2hr at 192k/24 in a couple of seconds. You want to do movies and keep them in sync, I consider that outside serious music listening?

The Sony Discman ESP portable CDP's spun the disc at higher speed for a few seconds until the FIFO was at specified capacity and then settled back to 'normal' disc spin speed.
These players would also run multiple read retries on scratched/damaged discs.
IIRC the buffer memory chip capacity was surprisingly small.

"Everything they make sounds like .... " sounds exagerrated to me.
While Behringer also has some "crap" products they also got some stuff whose price/performance ratio can`t be beat.
Regarding that interface I am pretty sure it can rival 2-300 EUR ones sound-wise.
Harry, we know that you laugh at us. We, in turn, laugh at your foolishness in not understanding what we are all about. We are serious, and you are just a reactionary. '-)
You are correct John, I do chuckle at the 'experts' who insist that what I have, or BQP cannot have effect.
Harry, you really have less than zero idea of what's cooking.

What DAC are you using? I have yet to see reasonable data from these devices.
Personally I have tried Maudio Transit, ASUS XONAR U7, and the latest RTX6001. Have an RME Babyface Pro that I have not tried yet. But as you can see, this covers quite a performance and price range.

Main DAC here is a Benchmark DAC-3. It has one USB port, but mostly uses optical or coaxial SPDIF or unbalanced AES.
There are some other DACs here too, but not that use USB. I mostly use SPDIF, occasionally AES.
A long time ago I had an Maudio Transit. It's analog sounded awful, so I only used it for optical SPDIF

It's about time that the posts of these persons were put into a new thread -

Poynton, if you had paid attention you would have noted that I have
previously said that I do not like the effect of BQP.
Dan.
I found no effect of any kind, though opening it up was good for a laugh.
Understood. Previously you mentioned using EAC for CDs, which is a ripper app. So, maybe I could put it this way: they use encryption to prevent unauthorized copying of any kind. DVD and BluRay player apps as currently written only decrypt data in real time. To copy decrypted data for a DAC from a BluRay at high speed to a large buffer is not legally allowed for at this time since authorized player apps don't do that. It would be essentially unauthorized copying, or loosely speaking, ripping. Unless of course, you wrote a new player app to go with your big FIFO DAC and paid all the licensing fees to make it legal.
Regarding not enjoying the best all the time, you are right. The BluRay I mentioned is a good performance with great players, but unfortunately the digital audio recording of the performance sounds way too digital.

Effects, nothing, inside an embarasing collection of that sticky copper tape hand cut and an irreplaceable coin cell. Only a fool would think anything is happening.
Mark my only point is that we have the technology in spades, keeping up with the industry roadblocks has little to do with useful brain activity.
Also, one can look at the error rates that JensH and Victor got with the 9038q2m and 9018k2m, respectively, out of cheapo boards with opamp I/V's. E.g. Jens's I/V is sitting around -103 dB THD (3HD dominant) at 3.65 V output (SPDIF input). As his plots show, there's a moderate amount of hash up top, but that's *still* sitting a good -115 to -120 dB from the primary.

Victor's data, from what I remember, shows something similar using I2S input.
If there are major problems with these *cell-phone* chips SRC's or the rest of their pipeline, these two gentlemen aren't showing it. Could it be better? Sure, of course, but the conversation is starting with errors that are -100 dB or smaller.
