Bought this to connect my Mac to a stereo amp and speakers as my current main audio source.
I have it running from an AudioQuest DragonFly Back v1.5 DAC to a Rotel RA-820AX, which is connected to a pair of Tannoy Eclipse Ones via AudioQuest FLX/SLiP 14/4 Speaker Cable.
Previous interconnect was a Cambridge Audio Atlantic. The Tower brings much more taut bass and crisp treble with a nice full midrange. Highly recommended, and for this price with free delivery, you really can't grumble.
I'd also like to commend Harrow Audio on their excellent service, good information along the way, and provision of full tracking when they send the item out. Perfect!
