I thought I'd post a quick impression. I finally got around to listen to the rDac for the first time at home since buying it.
I started listening a few hours ago when I was actually very drunk. The drunkenness has worn off now though and I'm literally posting impressions from the last half-hour using only 1 CD track and listening to it 3 times now (that is, 3
comparisons, so actually 6 times) - so my impressions aren't very reliable. I typically re-listen to CD tracks on the order of 10 times (comparisons) or more to confirm & re-confirm my impressions (whether or not I'm writing a review - and in this case I will NOT be writing one), but haven't yet had time to do that of course.
I'm using my Arcam FMJ CD36 as a CD transport and the rDac slaved to it through the coaxial output with a Blue Jeans coaxial cable. Headphone amp is the HeadAmp Gilmore Lite and the headphones are my Audio-Technica AD2000, and the music I just used was Helloween's "Who is Mr. Madman?" from
7 Sinners.
The best thing I can say about the rDac is that it sounds a lot like the FMJ CD36. As well it should, since the FMJ CD36 uses the previous-gen WM8740 and the rDac has the WM8741, and both are made by Arcam.
Sonically they're closer than what I was expecting too, considering the rDac is $480 and the FMJ CD36 was $2.5K when it was in production. It's hard to be critical at this point as I haven't used my standard battery of music for the AD2K yet but probably the most "deficient" aspect of the rDac in comparison was keeping multiple layers clear-sounding as the music got more complex. I'm not very familiar with metal music terminology, but the accelerated drumming (I'm pretty sure there's a "metal" word that refers to this, right?) also sounded more accelerated and incisive on the FMJ CD36. Other than that, right now I'm surprised how close the FMJ CD36 and rDac are. My opinion could change later though.
I don't know if I'll be writing anything more about the rDac so please do
not ask for more impressions. I will definitely not be writing a review of it - full, mini, or otherwise.
