No. I did similar loopback using REW before and no such problem. I used Scarlett Solo as loopback device.I have tested my new Gustard x16 using REW with loopback to behringer UMC404HD and I found that it starts roll off fast starting at 8khz, has anyone encouner this problem?
Interesting.....How long have you owned ithe Gustard?Both connected via usb to Mac Book Pro, the gustard as output device and the behringer as input device and the gustard output to the behringer mic input
I see. About how many hours you think it was on totally?I have it for about a week. I have tested the behringer by loopback its main output to its mic input and I get flat response. The PCM filters should roll off around 18khz.
sorry, currently I can't but I attached my results:
Wow, it is pretty steep drop. For me, my well used x16 with filter 1 only drop by less than 1db all the way to 18khz.sorry, currently I can't but I attached my results:
Approx. 35 hours - l-fastWow, it is pretty steep drop. For me, my well used x16 with filter 1 only drop by less than 1db all the way to 18khz.
Which x16 filter do you use when doing this measurement?
Can you estimate how many total hours your x16 is actually powered on?
Also, what made you want to measure the frequency? The DAC sounds dull?
I was having that problem when connected to Macbook Pro with high sample rates set. I don't have any issues at 96000 Hz.I've been meaning to measure my X16 for a while. It just sounds so darn good, it's been tough to force myself to pull it out of the system long enough to run some tests.
I am hearing some clicking / distortion when playing DSD streams during silence or very low levels in the source material. This may be enough motivation for me to connect it up to the bench and see what's what. I'll share my results soon.
