Hi guys, I am planning on getting into some better quality audio, as i am starting to amass a decent FLAC music collection. I have a plan for what i want to do, and would like some input on what you guys think, keep in mind, the setup is for music playback only, no games(thats my other pc), no recording/mixing of any kind. Currently Have: Sennheiser HD650's http://en-au.sennheiser.com/high-quality-headphones-around-ear-audio-surround-hd-650 These are still brand new in the box, birthday present coming up next month. What i plan on doing, in order of purchase: DAC: Schiit Audio Modi 2 Uber http://schiit.com/products/modi-2 AMP: Schiit Magni 2 Uber http://schiit.com/products/magni-2 Source is an older LGA775 rig: Q6688 Quad Core @ 3GHZ GTX 295 GPU GA-P35-DS3P Mobo 4GB Ram Win 7 on SSD + storage hdd's. Soundblaster X-Fi Platinum (won't be used as using usb) PCI USB 3 card, which is what i plan on connecting the DAC to. How i plan on connecting this setup: Source ---USB(PCI USB 3 card)---Modi 2 DAC----RCA----Magni 2 Amp-----stock hd650 cable----hd650 headphones. I would also in the future(not at the same times as purchasing amp/dac) purchase a 2.1 setup. Monitors M-Audio BX8 Carbon's (2 set) http://www.m-audio.com/products/view/bx8-carbon#.Ve4X3tKqpBc Subwoofer M-Audio BX Subwoofer http://www.m-audio.com/products/view/bx-subwoofer#.Ve4YLNKqpBc How i plan to connect these: Source-----USB cable(PCI USB3 Card)-----Modi 2 DAC-----RCA---Magni 2 AMP-----RCA(from amp preout)-------Subwoofer-----TRSx2-----Both Monitors. I realize this is using an "unbalanced" connection due to using RCA's, though as just for playback from my research i don't think it matters, feel free to correct me on that though. For reference: Amp/Dac maximum spend is $5-700 US dollars 2.1 Monitor + sub setup maximum spend is $$7-1000 US dollars I realize that isn't alot of money, and i understand that, but i am new and just getting into this, and don't have a lot of cash laying around right now(11 month old bub). I will certainly upgrade in a few years if i feel the need to. Certain things i am worried about: I have been told on various forums etc. that: "Headphone amps are not good at running monitors" Though as i currently understand, if i am using powered monitors + powered sub, and only using preamp output for these from the amp, that it does not matter the amp, as it is just the interface that matters? "Magni/Modi stack will drive the HD650's but nowhere near their potential" Am i wasting these headphones by using a Magni/Modi stack with them? Well, i hope i have made at least some sense, feel free to pick me up on anything you think i am doing wrong, or could do better. Just so you know, i am located in Australia, and we do pay more for things here, and have a lesser range than other countries. Sorry for being such a long thread, and if you have made it this far, i thank you greatly for reading. Any help/info/suggestion much appreciated.
