I am very pleased with the results I got following that advice. It has been said here many times and my own experience agrees that for the best sound save your money on the amp, and spend the money you saved on your speakers. Human perceptions are heavily influenced by expectations though so your experience might be different from mine. I do not believe a boutique amp is going to sound any better than a decent receiver.


I do think computer sound chip makers work to a different standard than companies working on dedicated receivers/amps and that the dedicated solution probably is going to sound a little bit better. And it works with my 5.1 surround set up just as great as it does with my headphones! The receiver handles every digital format I can throw at it at any frequency/bit-rate I care to send to it. The receiver amplifies my headphones to stupidly loud volumes without any detectable distortion. While I do not need all the inputs and outputs nor use all the bells and whistles, it does what I do need very very well and at an impressive price. My searches and reading here at Hydrogenaudio is what finally moved me away from buying a boutique amp and I got a Yamaha receiver instead. I considered about a dozen headphone amps anyway! thinking I 'needed' one to fully utilize my headphones. It would not go quite as loud as the HD-555 (50ohm model) which is pretty much identical to the HD-595. It was loud enough for me with no detectable interference/hissing/static/distortions.

I have the Sennheiser HD-580 which is very similar to the HD-600 and HD-650 and I used it for years un-amped straight out of my motherboard's on-board sound. ) improvement in sound quality with a dedicated DAC? Another reason for an external DAC is some problems of interference I've had with the integrated provision, and as I understand it, I can expect a marked (albeit not life changing. Quote from: JacksonGrey on 09:04:48 However, I'd like to amp my headphones, and any future headphones I buy (HD-600/HD-650 etc) will surely require an amp for best performance. So my question to you is: Have any of you given these a go, and could someone with more expertise than me objectively tell me which is likely to provide the best sound quality? I apologise for how broad the term 'sound quality' is, but I don't like delving into the audio jargon (bass sounding 'fresh', 'alive', 'frigid' etc ), and I haven't the expertise to use a term more scientific. Unlike most other audio forums, the people here seem to have a reasonable approach to hardware without delving into psuedoscience. Their specifications all seem fairly similar, and whilst I'd like the option of being able to use RCA inputs with a headphone amp (as is the case with the Aune), it's not a deal breaker if, say, the Zero offers better sound quality without such a feature. My problem is that all the advice/reviews I've seen have been based on psuedoscience, with people claiming the superiority of one over the other based on cables, power supplies and so on. My price range is £90-£140, and there are quite a few budget DACs I've come across, namely:

I'm currently using Sennheiser HD-595s with my motherboard's Realtek offering and would like to upgrade to my first DAC-Amp combo.
