It is not the intention of these feature suggestions to complicate matters for James and his team.
It is just meant as a starting point for discussion of possible features. AmberOzL and I have been chatting about these, via PM, for a while, and thought it'd be good to hear what our fellow Head-fiers (and James) think.
The reason for this is that if the X7 is going to be a flagship DAP, then in order to compete against its rivals, it is going to need to offer some useful abilities which may not be present on competing DAPs.
- Multiple dynamic playlist creation ability (if this is too difficult/expensive to develop in-house, then it would be nice to allow use of 3rd-party software).
- 20mm maximum thickness
- 230 gram maximum weight (ideally 200gm max)
- 100mw minimum power output
- <1 ohm output impedance
- Must have hardware buttons for [REW] [Play/Pause] [FFW] [Vol - / Vol +] (all these buttons to be on one side of the DAP, so that squeezing the DAP to press a button cannot cause another button to be accidentally pressed at the same time). Sony NW-ZX1 is an excellent example of good button design.
- No slider-controls (e.g. Calyx-M volume control)
- No rotating controls (e.g. X5)
- Does not have to have a full touchscreen, as long as it has ergonomically-correct hardware buttons (like Sony NW-ZX1)
- Proper Gapless-play implementation in all modes
- No laggy interface, it should be as responsive as possible.
- Don't mind if DAC chip(s) Cirrus or Sabre or Ti, but request the flagship one and make it sound natural. Not dead flat, not extremely colored either.
- DSD not necessary - 24/192 playback is enough. (but some people will disagree with this)
- Digital-Out (prefer Co-ax)
- Balanced HO and LO (so dual dac likely). Ideally RSA type or (preferably) Hirose type connector rather than 3.5 or 2.5 TRRS.
- Minimum 8hrs Rebook .flac playback duration (preferably 12 hrs or more)
- 2 fullsize SD preferred, or (less good): 1 fullsize SD+ 1 MicroSD (but not 2 MicroSD)
I realise there are size and power requirements which might be problematic, but I would nonetheless like to open the topic of mSATA drives for discussion. These are not cheap, but they are competitive with fullsize SD cards, and, if one is willing to pay extra, they can currently reach 1TB capacity (http://www.samsung.com/global/business/semiconductor/minisite/SSD/uk/html/about/SSD840EVOmSATA.html). I'm not proposing that the X7 actually be sold with an mSATA drive, but that (maybe) it could have the option for users to buy an X7 empty and then fit an mSATA drive of their choice. http://www.dabs.com/search?q=msata I'm not pushing this issue, I'm just interested in discussing it, as it could potentially be a killer feature for a groundbreaking flagship DAP (remember the X7 won't hit the market until 18-24 months from now, so mSATA 1tb drives will be cheaper by then). FYI, mSATA dimensions are 55 x 30 x 4.85 mm. That might sound relatively big, but it really isn't much larger than 2 x SD slots.
Interested to hear people's thoughts on the above proposals (including James!)
