Introductory Notes | Invicta DAC Was approached by forum sponsor Custom Cable enquiring if I would be interested in the loan of a Dac to compose a write-up. Which one? [answer] [ ] [ ] Replied that there would be two conditions; I would be (a) honest and (b) cannot provide any favours to manufacturers. [Agreed]. But still hesitation on my part. Explained such undertakings are better with companion systems for comparison and unfortunately my Dacmagic and stereo amp are not ideal for that task. [Optimistically provides suggestions] [Steven, that is sold out as soon as it comes off the boat!] [But .] Just over a week later and rabbit out of the hat, two further Dacs sourced! For clarity and completeness: This is not an official AVForums review. No remuneration has been received; financial or otherwise. The only benefit gained has been the free use of the systems in my own home for just under a week. My opinions are my own only. Perception and personal taste of sound is unique to the individual. It might also not be possible to translate accurately into words what one hears. And huge appreciation to Custom Cable for entrusting several thousand pounds worth of kit to my custody and of course for making it possible. Review Dac: Resonessence Labs Invicta Comparison Dacs: Audiolab M-DAC, Teac UD-H01 Source: Invicta built-in SD, iMac with optical and usb out Source Material: Wav, Flac and Lame encoded 320kbps MP3 files / Ultrasone Test CD in Flac Headphone Inventory: Sennheiser HD600 with HD650 cable, Phonak Audéo PFE 232, Shure SE535 As a renter, I do not have a big speaker system. So testing has been done as a headphone amp only. All the Dacs have been run in. The HD600 is nearly four years young. The two IEM were purchased only very recently *ahem*. There will also not be a single graph below. Firstly because Resonessence have released a comprehensive document that is informative and contains many measurements here. Secondly 6moons has included a technical analysis in their review here. But mainly because I am not going to pretend to understand acoustic science speak.
