Thanks everyone I appreciate your thoughts and comments. I'm pretty new to this digital end of audio and it can be a bit overwhelming.
@fastfreight thank you. I found the Mac Disk Drive that is highlighted in your post. But if I rip them to an external hard drive, how do I play them ? My Frerot DAC does not have a USB 2 in or out, and my amp and preamp have only RCA connections.
@evanpress may I ask which fast CD player your purchased ? Can it also be used as a CD burner ?
@8th-note thank you for your post. What is a DAP ?
@devinplombier thank you. I'm sorry but I don't know what you are saying. I understand FLAC but not the other two terms in CAPS.
@gkelly yes most of this is like a foreign language to me.
To the many who suggest to get the Mk 3 and be done.... I am leaning that direction. I thought I was happy with my current Denon streamer but it is fiddly and so much so that I sometimes have to unplug it and re-connect to power to get it to obey commands from my iPhone again when using Tidal, where my WiiM Ultra is not fiddly with Tidal. And I will always wonder what a better streamer sounds like. The Innuos Sense App has a great reputation. I have emailed Innuos support about possibly integrating the Mk 3 into my system and received help the same day which I feel is excellent. The only question I have is: their suggestion to connect Zen Mk 3 -> USB -> Frerot DAC -> RCA -> Pre amplifier. Is this correct ? My system:
Van Alstine SET 400 Amp
Van Alstine Transendance RB Tube Preamp
Merason Frerot DAC and Merason walwort power supply
Salk Veracity HT2-TL speakers
Any other thoughts and comments are appreciated.
