What would be a good portable Dac/Amp to use with my HD6xx and Sony Xperia 1 V cell phone?
I am new to this hobby. I purchased a HD6XX and plan to use it with my Sony Xperia 1 V cell phone, that has a 3.5mm jack. I was wondering if I needed a portable dac/amp or just a portable amp and if so what would one recommend? Any assistance one could provide, would be greatly appreciated. Kind regards, Haz

I don't think this has been resolved even with Philips stating this.
Philips X2 Statement Dear forum users and readers,
recently we have seen some posts discussing variations in the Philips Fidelio X2 headphones. In response to that we’d like to inform you as follows. Our extensive testing has shown that Philips Fidelio X2 headphones continue to meet our stringent quality requirements, including those on acoustic performance. However, as part of our approach to continuous product improvement there have been following modifications:
- Ear cushions are fixed by glue in individual batches: In an attempt to improve the manufacturing process, glue was added to the pins which support the Philips Fidelio X2 headphone’s removable cushions. Acoustic testing showed that this did not impact sound quality, however this modification proved excessive leading to some cushions not being detachable from the headphones in individual cases. For that reason, it has since been removed from the production process.
- Differences in ear cushion material: A more durable and consistent material was applied in later batches of ear cushion production. A slight color change is visible, but both old and new materials deliver the same acoustic performance - Variations in sound quality for headphones produced at different times: The acoustic tuning has not changed since the Philips Fidelio X2 headphones were introduced, and all products have been tested against identical golden samples.
- Hi-Res Audio logo is only present on the packaging of later batches: All Philips Fidelio X2 headphones meet the stringent Hi-Res Audio requirements. Confirmation of accreditation was received in April 2015, and since then all packaging printed bears the logo.
As has always been the case, Philips Fidelio X2 headphones is only produced in our authorized and quality controlled factories, and this will continue in line with our high standards. We are proud of the quality and performance of the Philips Fidelio X2.
again I am just relaying what philips stated. I am no way stating that its resolved. I returned the pair to amazon since the metal rings were warped and the sound form the right ear was way off.
For $200 I'm in on this Drop, and I really hope these are a newly manufactured batch with ALL the changes mentioned in that thread.
Not that there is necessarily anything wrong with that if fully disclosed. Hopefully we are all adults here able to make rational decisions :)
I wanted to investigate this as thoroughly as possible so I apologize for the delay in response.
From what I can gather, the units with sound quality issues seem to be isolated to a specific production run that was acquired by Amazon. Our units do have a small amount of glue on holding the earpads onto the four pins, however our vendor who verified this for us was able to completely remove it very easily using his fingernail.
I feel confident these are solid units given the following: 1) Time our units were produced (more recently but apparently previous to the glue no longer being used). 2) Philips products are always purchased by the 40 foot cargo container full, so unlikely to be from the same production run. 3) All accounts I've been able to find of sound quality issues come from the batch at Amazon with QC problems. 4) Philips seems to be replacing those affected without a problem. 5) You always have the Massdrop warranty to fall back on.
I'm also having a pair overnighted to our office and we'll be testing them to see how they match a pair of Woox built X2's that I have on my desk ASAP.
Please let me know if you have other concerns and I'll do my best to clarify, but this is the info I have for now.

Decisions decisions...
I was thinking of getting a second pair for safekeeping! To be clear, I already have a pair that is almost a year old and love them.
