Hi friends, As you will gather, I’m new here; although, I’ve read numerous helpful and informative articles, comparisons and opinions. However, I am truly at a loss and have reached a point where reading and trying to understand things for myself is not a very cost effective nor wise audio strategy or solution. I’ll be as brief as I can, I’ve recently ‘stepped up’ my audio equipment both in terms of iems and cans. At present I have two top shelf sony iems and the isine 20. For cans I just ordered the Fostex th900. I also got a DF colbalt as the store rep convinced me it was a great pairing with my Sony’s. (As an aside, I’ve never really invested much in Dacs, the only other one I’ve have and owned is a Fiio e17 Alpen. I like the cobalt for portability. The Fiio e17 I haven’t really bothered with all that much.) In any event, I have the cobalt for transport, which is fine, but I’m writing about a desktop setup. My top shelf Sony and Fostex cans are/will be for office desktop use. Is the Cobalt enough? I know there are plenty of different views on this. Ideally, I want something that I can plug into and be done with. I find myself tinkering and exploring with settings and levels and eqs, and it’s like, what did I get this stuff for in the first place? To constantly be searching for something else? Or to endlessly tinker with sound so that each and every song I play sounds like I want it to? It’s frustrating and is spoiling my appreciation for how fortunate I am to be in a position to own some pretty okay stuff. I will say, however, that the ISine is the only product that I’ve stopped tinkering with. I set the eq and I am totally content. No touching. The cobalt on the other hand? I plugged my Sony into it today and any female s sound is like someone inserting a pin in my ear. Way too sharp. Of course, I adjust treble and the next song is a mess. Shoot me. I’ve taken the situation above to my absolute limit. Hence me reaching out to the experts here who are much more knowledgeable about this stuff than me. I don’t exactly trust store reps. I’m not saying the rep was dishonest, heck, maybe he is right for all I know, but he told me the cobalt was a great option for me. Even when I explained it was for desktop use. Lastly, based on some research and mostly due to availability, I wonder about the Marantz HD 1dac? It’s available nearby and seems like a pretty good option. But hell, I don’t even know if it is needed at this point? I won’t buy online so that narrows things down to what I can find locally. I don’t want to invest more into this if the life of chasing great sound involves turning knobs endlessly or going to school to become an audio engineer. Save me! Apologies for the length but I hope you will understand. I just want to get some solid advice and be done with it so I can just sit back and say, I’m happy. I love my music. Thank you, kindly.
