I am thinking seriously about getting the new line of Adam monitors, the S2V series.
I want to help you and share my experience.
At the moment in my room I have 3 pairs of monitors:
Adam S2V, Adam S3V, JBL 708p
All of them have DPS inside and AES/EBU digital inputs (as well as analog).
To play music, I use one Windows PC and 3 external audio interfaces:
1) RME ADI-2 DAC for Analog XLR output to Adam S2V
2) Singxer SU-1 for USB->AES digital transport to Adam S3V
3) Singxer SU-1 for USB->AES digital transport to JBL 708p
All 3 audio interfaces connected to my PC using USB.
AES/EBU digital connection a bit more practical because you need only one cable from interface to the first monitor, and if it's long - it sometimes nice to have one long cable than two long cables in terms of ergonomic and esthetic points of view.
AES digital connection is simple. One cable from interface to the first monitor, second cable from the first monitor to the second monitor. That's it. Very simple and nice.
If you connect monitors using AES EBU digital connection - all Digital to Analog conversation happens inside monitors. However, the quality of AES input is critical. That's why I chose quite cheap but good Singxer SU-1 digital USB transport.
Singxer SU-1 has galvanic isolated USB input and femtosecond clock. They use XMOS chip, and I bet they have asynchronous USB connection which is better for audio transfer than "normal" as I think after reading about it. This device has many good reviews from users.
After talking with one guy, he told me that I could not have good Digital to Analog conversion inside the monitor and a good external DAC (he recommend me ADI-2 DAC) should sound better. After that, for an experiment, I decided to buy RME ADI-2 DAC.
Two times I compared two audio output setups:
PC -> usb -> ADI-2 DAC -> analog xlr -> Adam S2V
PC -> usb -> Singxer SU-1 -> digital aes -> Adam S2V
ADI-2 DAC has no USB galvanic isolation, but somehow I didn't hear any bus/power noise using it.
First time I detect no differences by hearing and decided to use a microphone to record and listen.
After listening to recorded files I liked RME a bit better in vocals, but after all, I realized that Terrible EQ on ADI was +0.5dB and I think total volume level was not calibrated to have the same volume from both setups.
After 1 week of using ADI-2 analog outputs, I compared again.
The problem in comparing is that Adam S2V monitors need some time to reboot if you make changes thru ADAM S Control software. It takes me about 20-30 seconds to switch between Analog and AES inputs in Adam.
Btw, Adam's software is terrible.
Because of that 20-30 seconds pause even while listening to the same part in the same song it's very different to hear any differences.
I could not notice any differences, and finally, I decided again to use a mic, but the second time I used UMic2 miniDSP USB microphone to record both setups and listen to them with an ability to change between two records immediately.
I verified that Terrible and Bass EQ in ADI-2 DAC set to 0. Also after volume level compare (by hearing) I set ADI to -1dB to match sound output.
After recording and comparing of wav files, during my second test, I noticed no differences at all.
Today I'm going to test it again in the third time, but this time I'm going to calibrate volume levels of both setups using the software measurement. Calibration microphone sounds terrible and I'm not sure it's valid to compare sounds recorded by calibration mic. Also, I have Shure CVG18D-B/C mic and Tascam UH-7000 for it and I have another USB mic - Blue Yeti. Maybe I should use it. Don't know. But again, by hearing only, I could not notice ANY differences in both of my tests.
Honestly now I think that if the sound from Singxer SU-1 using AES is the same - it is more practical to have SU-1 and use AES cables.
However, SU-1 has no mic preamp and no volume control.
RME have much better support, website, drivers location than Singxer. You even cannot download any drivers from Singxer cheap looking website.
However, the device itself looks ok and sounds ok as well.
Regarding monitor suggestion - also, I want to buy Dynaudio Core 59 (they also have AES EBU digital input), they have smaller Core 7 version. I want to experiment again. I have no idea how they sound. Also, I never listen to Tedd.
I think Adam S2V is a good choice. I compared them in one studio with Amphion two18 and noticed almost no differences in details/sound etc. Despite Adam has terrible Windows software, S2V is very cool looking and very good sounding monitor.
I use my monitors for music listening and I don't think they sound "monitor" - they sound amazing and "musical". I like the sound of Adam S3V better in the nearfield and JBL 708p better for midfield. But it's in my room, only for my room acoustics. Your room is different and you will hear sound in a different way remember it.
