Question about inner workings of M-Audio M-Track Solo vs SybaSonic DAC

Specs as best I can find:
1. SybaSonic SD-DAC63118, DAC/ADC: C-Media CM6533, Op-Amp: TI-LM4562
2. M-Track Solo, TI Burr-Brown chip (from Linux info), unknown on the rest.
Both are USB input/power and RCA out to my Fosi V3 Amp.
Using them as a PC onboard audio (ALC1200) replacement.
Both are plug and play (use the same MS built in stock driver).

1. The Syba drives the V3 amp or headphones much harder/louder (like twice as loud at same volume position). It behaves similar to using the optical output of a sound card, shown in Windows as a SPDIF out and has no effects tab. I swear I can hear better detail in music with it vs the M-Track.
2. The M-Track behaves like analog outputs on any other sound card, and has an effects tab with Loudness EQ, etc. A feature I really want to have for those annoying "super quiet dialog > super LOUD BOOM, SCREAM!!!1" movies. Audio quality seems a bit anemic compared to the Syba at the ~same volume.

So in short, the Syba sounds a bit better, but lacks any/all effects. The M-Track has effects but seems inferior otherwise, weaker/no preamp. Why? Are they totally different types of devices, or am I just seeing the quirks of the particular chip sets used?
The ultimate goal = get Loudness EQ while using the SybaSonic as a DAC? Maybe some lightweight, simple program I can use for that?

Still curious about why they behave differently, but this here post led me to a solution on how to add the missing Enhancements Tab with Loudness EQ via the registry back to the Sybasonic DAC.

It's a bit tricky because you have to change some permissions in the registry to make changes, but for the brave who want to know how to do it...

*It's the registry! Make backups of things you are about to change.*

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render

1. {string-of-seemingly-random-numbers} = Find the target audio device by looking inside the Properties key. The default device root key will be "DeviceState = 0x00000001(1)" the others were (4).
2. You'll probably have to change permissions/inheritance on it from "System" to "Administrators" (assuming you are one)
3. Then in the FxProperties key (did not exist), create/add/replace the following string values:

{Valuename} {Value}
Code:
{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},1     {62dc1a93-ae24-464c-a43e-452f824c4250}
{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},2     {637c490d-eee3-4c0a-973f-371958802da2}
{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},3     {5860E1C5-F95C-4a7a-8EC8-8AEF24F379A1}

Example registry export from SybaSonic DAC afterward:
Code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{b4f400e9-e8ed-41ee-88f9-042e00590f13}\FxProperties]
"{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},0"="{DFF21CE1-F70F-11D0-B917-00A0C9223196}"
"{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},1"="{62dc1a93-ae24-464c-a43e-452f824c4250}"
"{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},2"="{637c490d-eee3-4c0a-973f-371958802da2}"
"{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},3"="{5860E1C5-F95C-4a7a-8EC8-8AEF24F379A1}"

Note: "{d04e05a6-594b-4fb6-a80d-01af5eed7d1d},0"="{DFF21CE1-F70F-11D0-B917-00A0C9223196}" appeared on it's own after a reboot along with some other stuff. As far as I have found it is for the following but mine showed as "SPEAKER" on a "SPDIF" device, so yeah...dunno, whatever works?
