Hi @schleppsound I’m new to quality audio equipment and would appreciate your help and advice. The only decent pieces of audio equipment I own are the Audio-Technica ATH-M50s/LE headphones I bought back in 2011 primarily for watching Blu-rays at night and the 1more Quad Driver earphones/IEM’s I bought last year. Right now I use the Quads to listen to AAC files on my iPhone 6s. A few months ago I stumbled upon the Dragonfly Red being mentioned in an article and that sent me down the path of learning about DAC/amps. I was thinking I would buy one of those until it sunk in that the compressed files I’m listening to are a bigger problem in my chain than the iPhone’s DAC. I’m now looking to get a DAP and sign up for Qobuz’s Sublime subscription so I can stream their catalog while I use the included discount to build a good Hi-Res collection. I’m currently looking at the SR15, the FiiO M11, and the iBasso DX150. Oddly, I can’t find anyone selling the 150 except a couple random people on eBay. My question for you or anyone else viewing my post is whether or not $700 is overkill for a DAP if I’m only listening with the Quad Driver or maybe even the M11 is overkill? I don’t think either would be, but I’m new to all of this and would appreciate the insight of more experienced audiophiles. My personal opinion that they wouldn’t be is based on a review of the Quad by Chris Martens on Hi-Fi+ (linked below). He listens to them using his reference DAP’s the Questyle QP1r and the Lotoo PAW Gold. The part of his review that makes me think the S15 or M11 wouldn’t be overkill is this quote about listening to ‘The Mermaid’ from Norma Winstone, Glauco Venier, and Klaus Gesing’s Distances [ECM 16/44.1]: “To be honest, this track can sound quite good on many different transducers, but it takes a special in-ear headphone like the Quad-Driver to draw out the full, rich tonal colours and the sharply focused textural and transient sounds of which the song—at its best—is capable. Stated another way, the Quad-Driver is an in-ear headphone for listeners who are ready to step beyond merely ‘good’ sound to enjoy something noticeably better than that.” http://www.hifiplus.com/articles/1more-quad-driver-universal-fit-earphones/ Now I’d love to invest a bit more and buy some Noble Savannas, but I feel like if I did so soon after buying the Quad I would be tossing away the $200 I paid for them. Thanks for reading my post and I’d appreciate any advice you or anyone else here can provide.
