Hi Howdy!
Yes, I still listen to my DX90 through my iDSD. I just fell asleep listening to the combo last night. Had a mini-RUSH-fest grouping Grace Under Pressure, Moving Pictures, and Permanent Waves. By the time I had gotten to Peter Gabriel, I was dozing off. I guess I'm still in the honeymoon phase with my Beyerdynamics T1 ver.2 headphones. Though the combination sounds awesome with my Sennheiser HD-650, 800, AKG K550, K545, And JVC ESNSY headphones. Almost anything sounds good with my Koss PortaPros, so I usually forget to mention them. The one thing that I know the iDSD Micro can do that the MOJO can't is drive my JVC SZ-2000 headphones into TRUE "Beast Mode". Example courtesy of @HawaiianBadBoy, if you get a chance to search him out, I think you'll be very impressed. If you're not a basshead at all, it may not be of real value to you, but it translates well into demonstrating how WELL the iDSD can drive the 600Ohm T1 with real "authority". Not just to make it louder, which isn't hard at all to be honest, but makes it possible for them to sing while almost feeling effortless. My Schiit Audio ASGARD 2 doesn't make them feel any fuller than the iDSD does. Yes, the HD-800 and to a much lesser extent, my HD650 improve slightly, but nearly enough to notice unless I A/B the HD-650 back to back between the two. I can tell with most quality tracks on the HD-800, but it isn't as big a difference as you would expect. Not even considering portable and non-Class-A amplified vs dedicated desktop/rack Class-A amplified. Which to me is a hugely impressive feat. Yes, I'm sure if I upgraded to a Cavalli, the difference would be much greater, but I could say the same between the ASGARD2 and a Cavalli as well. In short, I love it. It is the "Swiss army knife" of my audio collection. Only thing is it does EVERYTHING really well: excellent DAC, great sounding amp, TONS of power, "fairly" portable (It is on the large side, and not "pocketable" in less than a large jacket pocket or cargo pants as opposed to my FIIO e17 which easily fits in a pants pocket.), very durable, and has good battery life. (I've flown multiple times from NJ to California, and never ran out of power.)
Oh, I just saw that you asked someone else, so I connect my DX90 to my iDSD via coaxial. I had a custom cable made by Forza Audio Works. It works perfectly! The stock coaxial to 3.5" cable worked okay, but the plug sleeve started to soften and stretch, so the connection became a bit of hit or miss after a few weeks. The Forza has been rock-solid and shows no sign of wear at all almost a full year of travel later. Worth it in my book. And I have used the iDSD Micro with both my iPhone 4S and 5 as well as my iPad original and Air tablets. I have to use my old style and lightning camera connection kit (CCK) adapters, but it does work. Just for me, there isn't NEARLY enough storage to make it worthwhile. I know TIDAL works, but I really like listening to my own lossless files better, and having 128GB micro SD cards for each genre, and a couple for "travel music compilations" makes it easy.
Thanks for the Big reply!
I have talked to hawaiibadboy a few times on this and he seems to really like it still and has many other iFi products as well. I hope to have this tomorrow so I can finally have a listen. Its funny you mentioned Forza as I just had to cables made from him and just received them the other day, one for my Oppo PM3 and one for my Alclair RSM customs. He does great work. Well, I will have to give some impressions soon. Im really surprised that this thread does not get more attention. I will have to help spread the love.
