Philojet: I'm also cheap but am addicted to good cables. I already mentioned a couple of excellent stereo mini-to-RCA iPod style interconnects, and I own some of each. The first is the Zu Audio Mission iPod cable. This is a cable designed to sell somewhere around $200. Yet Zu and other storefronts put up new or slightly used ones on
eBay all the time. If you check the completed auctions you'll see that people are picking up 1M examples for anywhere from $25-45. These are *excellent* interconnects--fast, clean, smooth, full-bodied.
The other is an AudioQuest blowout at MusicDirect.com. I picked up one of
these, a 3M AQ mini-5, retail $209, yours on closeout for $59. It's superb, and a gift at $59. If you need more length, here's an
8-meter mini-3 at the same price.
And if you need still more flexibility and length, go
here for a selection of AQ mini-3 and mini-5 mini-to-mini cables (male at both ends) and a mini-plug extension cord (female and male).
If you want to use interconnects you already have, get one of
these or something like it. $12.95 gets you the adapter at the mini-5 level of conductor--PSC+ (PCOCC six-nines copper with gold-plated connectors).
As to the Dragonfly's connectors, they're first-rate: silver-plated and thick and sturdy. Sliding that AQ mini-5 cable into the Dragonfly's stereo mini feels slick and secure.
I haven't listened to the HRT Music Streamer II, but the October 2012 issue of Stereophile is a Recommended Components issue. According to them, the Dragonfly is a Stereophile Class B component, same as the $500 HRT Music Streamer Pro, while the Music Streamer II and II+ are both Class C.
