Doing some quick googling on it it seems ok. little too expensive for what it is.
For half the price you could get something like the Fiio E10k to drive those headphones easily. I used that little thing to drive my Beyer's which are a little harder to drive than those 598's. If you want something with more power in it than the FX Audio DAC-X6 is a good option as well. Never personally used it however.
If you want to stay internal, than you could honestly go with one way cheaper to drive those headphones. Other option I would personally consider is the HT OMEGA FENIX for less money. That all said, the Strip seems totally fine.
