I have the A8...
Jack of all trades, master of none. Which is the appeal - it's a one box solution that does everything reasonably well:
- Streamer - I'd rate it slightly cleaner than the ifi Zen Stream (£500 RRP) and about the same as the Zen with iFi power (£800 total)
- DAC - it's your typical fairly well implemented DS DAC, it'll do the job for many, I imagine comparable to many £500 Topping/SMSL DACs (for me it has that tonal sheen over the top I can't get on with). Not a patch on a £1.2k Merason or Qutest DAC.
- App - is really rather good, works fast and well.
- Unit - decent solid design, lots of ins/out, nice touch screen, handy remote
- Pre-amp - It'll do the job in some cases, not great but but in a lower end system may be adequate
If you want a convenient simple solution that does a respectable job for a reasonable price it's hard to knock, you get a lot squashed into one box. If you want to perfect your chain then you can assemble separates for the same price, or maybe a little more, for better SQ and whole lot more cable spaghetti.
