You're welcome and don't hesitate if you need further advice.

BTW, to have eq and dynamics integrated into a recording interface can be practical for some use cases, but is not necessarily needed.

You can use it to EQ your active monitors or headphones for the monitoring mix or when listening to music to make it more HiFi'ish and less neutral sounding. Or to give an input signal more boost or to give a singer a little reverb when doing vocal recordings a d the singer needs it to feel more comfortable. Adding FX through USB/TB can create a noticeable delay which is maybe tolerable for reverb or delay effects but this latency will become much higher with increasing ASIO buffersize which might be needed to reduce the processing/interrupt load on the computer.

For pure recording purposes you do not necessarily need FX effects.

If you would tell me your demand (use cases), what types of interface you need (USB or PCIe), your current setup, what devices you would like to connect with the new RME solution, how many and what type of i/o channels you need and your budget for that, then I could help you to find a good solution.

You can take either a suitable USB or PCIe recording interface with or without analog i/o and/or FX as a basement or -  if you want a really outstanding solution with a lot of useful features - the combination of such a recording interface with TotalMix FX and a high end converter like ADI-2 DAC/Pro.

The following blog articles can give you a good overview, to give you an impression what's possible and - should you have interest for such a converter - to plan for an additional port for it. In the case of the ADI-2 Pro this can be ADAT, optical or coaxial SPDIF, AES or USB.

An additional device like the ADI-2 Pro can serve you well with a lot of useful features which are unique to this device:
- excellent ad da conversion
- support of four reference levels and a feature called auto reflevel that automatically chooses the optimum reference level so that SNR and dynamic is optimum over a much wider volume range (honours also B/T, PEQ and dynamic loudness settings in the calculation to select optimum reflevel)
- ear protection by slow ramp-up of volume when plugging phones or switching between monitors and phones
- bittest to be able to perform an end to end test whether audio from a PC player was received lossless to ensure/check highest quality playback
- 5 band PEQ to compensate deficits of phones or hearing weakness, even  possible per channel
- B/T controls to compensate bass and treble for bigger differences in music material/masters
- dynamic loudness so that music keeps it's body if you turn down the volume
- support for DAD in case you want/need it
- different levels of crossfeed
- extreme power headphones outputs driving even phones that need a lot of power
- balanced mode for phones in case you want it
- useful status screens with the possibility to troubleshoot digital connections better
- SRC (sample rate converter) to connect devices with fix clock like DAT recorder
- two dac chips to connect and compare phones at the same type of da converter
- can act as a monitor controller for your monitoring section finalising the end volume  so that a 0dB fader setting in TM FX can not harm your ears and/or equipment just in case you performed no proper level matching eg using attenuators if needed.
- possibility to choose between different DA filter of your DAC for eg either most linear frequency courve or to use have an emphasis on other things of a little bit higher separation of certain percussive music instruments. These are only nuances and might depend on your room, equipment, etc (see one of KaiS's postings).
