    My choice is MOTU M2. Better ADC/DAC, lower noise, the loop function (you can record and mix any sound your PC can get from internet and stream all together).

    The opinion I made is from specs and reviews, but I didn't tested myself none of the devices.

    Are you kind enough to share your own experiences with these digital interfaces?

    Thanks.

    A LP is only going to have 12-13 ENOB when you get down to brass tacks, thus either should work fine if properly set up with your recording software and such.

    Yes, I know, but a poor ADC add its own noise to the needledrop and give mud to the sound. Some cheap ADCs with SINAD -70-80 dB add a 1 KHz spike and harmonics of annoying noise and lot of THD+N. A high quality ADC must output 17-20 ENOB (<0.0095% THD+N).

    Either of those ADCs should have over 100dB SINAD if working properly.

    Bob that Simple Minds sample I provided awhile back in that 45 vs 33 thread, I believe you commented on was done with a 2i2 Gen2

    Sorry for the OT, I question you needledrop experts: Can I connect my pre-phono to my laptop via an rca to usb cable and record needledrops with Audacity, or I must have an ADC convertitor in between pre-phono and the computer? Be patient I am completely green when it comes to the cyber world

    That won't work. Some folks use an RCA to single 1/8'' stereo jack to the line in jack on a computer, but that won't work on every computer and in many cases the on-board soundcard is low quality. If you want phono preamp to USB you will need an audio interface of some type.

    Thank you, in two sentences you have clarified all my doubts, I have spent the whole afternoon searching on the internet. Much appreciate it. Best regards

    share us your settings where you find your truest dac on the RCA out.
    I use 44100 on 1024 if I have a high resolution album. To the RCA out either playback or recording, it sounds very close to a well amplified vinyl.
    or 44100 on 256 is always my standard. The built in dac I could never ask for anything more. But if the file is not recorded well. it can sound like a plastic digital.
    .. What setting do you normally use?
    I haven't got around the performer plus yet. What is your take on the software and what is its strongest point?

    Synthfreek Drum machines are not inherently evil.

    This is almost what you need, seems like adding a 1/8” to rca adapter would do the trick.

    The MOTU M2 digital interface I use is very quiet. Clean and sound. PCM 192/24-bit max. resolution.The noise floor induced by MOTU itself is -97 dBFS total RMS. The aggregated noise floor induced by preamp + interface (Cambridge Alva Duo, Motu M2) in needledrop is -90 dBFS total RMS. RCA interconnects. XLR interconnects must get better values.

    These are good values and the recording chain may be considered transparent. This noise can be easily removed in post-processing stage with software.

    MOTU M2 ADC: AK5552...............(S/N 115 dB, S/(N+D) -106 dB)
    MOTU M2 DAC: ES9016 Sabre.....(S/N 124 dB, S/(N+D) -110 dB)

    The maximum vinyl SNR is 60-65 dB around. The master tapes SNR is limited to 70 dB.

    Here are the 24-bit spectrograms.

    Thanks for the response. I haven't taken measurement on my M4 but so far Ive done so many recordings in it. After I got it all ripped to lossless the output is very clear, punchy and warm. It sounds like I ran it through a high dollar mixing board then analog output. Best recording Ive done so far.
    I was playing with the setting last night. Ive recorded Phil Collins Seriously Live - Berlin 1989. The sound is just totally amazing. Very nice midrange holographic 3D sound on my system. The bass is just phenomenal with extended highs and its clear with warmth....
    In regards to my remaining LP that I haven't ripped yet.. Now it makes me feel I wanna buy the best sounding cartridge for my turntable in recording purpose. I wanna rip the original non-remastered albums and transfer it my high fidelity cassette deck.
