      I absolutely get the usefulness & neatness of a touch screen, but the fingerprints on such an expensive device would drive me crazy. I would at least include a cheap stylus so you are not constantly cleaning the front :)
      (Yep you can buy one yourself for next to nothing, but it would be a nice touch to pop one in the package!)

      Or a nice pair of white gloves, which is often what I actually do use when handling and operating really nice equipment. Although I defy anyone to not put on a pair of white gloves and then immediately do 'jazz hands'!

      Yes, Absolutely Unavoidable, but definitely always better done when no-one else is around! :)

      Hi Steve, thanks for the review.

      Just after the conclusion you’ve mentioned the Datasat Ls10 as an option that processes full-fat 9.1.6 Atmos..I’m pretty sure that’s incorrect and that it’s actually limited to 11 channel processing.

      I think you’ve also mixed up the inputs with outputs after the conclusion.

      At the price the Altitude 16 retails, I just can’t see how the Accurus would compete when you have the Optomiser and remapping on the Trinnov option.

      I believe the LS10 is limited to 13 channels of processing but you're right that's still not enough for 9.1.6 or even 9.1.4, so whilst it is an alternative to the ACT 4-16, it isn't enough to compete with the ACT 4-20 or Trinnov Altitude16. As you say, the Altitude16 is streets ahead of the competition in terms of its features and set-up.

      Steve, I’m pretty sure the Ls10 is limited to 11 processed channels with Dolby Atmos - but 13 with Auro. Even the Rs20i is limited to 11 with Atmos and that’s the flagship with 16 output channels! But it’d be great if you can check to confirm - it’s one reason I sold my Rs20i and I’m sure neither unit has yet overcome the limitation.

      Hi Steve,
      What "mainstream" pre/pro would you say comes a healthy second to this?

      If you want to save a few quid ;)

      Surely no room eq at this price is quite an admission based on the competition?

      9/10 for a £12k processor with no room EQ? Pull the other one! :laugh:

      I'd get the Arcam AV860 if I was looking for a more affordable AV pre amp processor.

      You might be right Sammy, the website is fairly vague and I've never actually reviewed the LS10. As you say, the Altitude16 is a no-brainer at this price bracket.

      I'm just reviewing the dARTS system at the moment, and the ACT4/dARTS combo is a mighty set-up.

      @Steve Withers Greetings, Mr Withers! Overlooking that this Acurus doesn't have room EQ, once it is manually equalised it is mighty fine. For argument let's consider only 11 channels. Judged on sound quality alone, how does this Acurus (after manual equalisation) compare with the Trinnov Altitude 16? Which has the better sound? You will realise that this is a theoretical question for me, because I'll never be able to afford either machine!

      Theirs no basis to consider a comparison of 11 channels only when the Altitude not only outstrips the Accurus for channel count and Eq, but is also non dsp based meaning it’s not immediately hardware limited. The re-mapping function is also something that is unique to Trinnov and no other processor has anything remotely similar...imho.

      @sammy the squid All valid points, but my question about pure sound quality between the two machines remains.

      I think the Trinnov sounded best Ken.

      Steve,

      You mention the second hdmi out is 1.4 for legacy connection. What would you want to connect to for this restriction? Understood to use on uhd Blu-ray where you might have a non 2.0 av receiver. But are any projectors or TVs disadvantaged by a 2.0 connection. Is it that the HDMI boards are designed for / from uhd Blu-ray players? At this price point and time I would expect configurable options like on HDFURY not limited.

      If you connect say an OLED to the 1.4 output what do you lose?

      Regards

      Kevin

      This is just bonkers no builtin RoomEQ for that amount of money when you have Lyngdorf MP50, Datasat and Trinnov in same price range.

      I think it's similar to USB 3.0, whilst mostly backwards compatible, there are some devices out there that just don't play well with USB 3.0, and will only work on USB 2.0 or 1.1 ports

      I don't even get the point of a touch screen on the processor, I'd rather sit down and use an on-screen display or a remote app. As for no EQ, well it's the first thing I check for when considering a processor / AVR.

      To be fair to the Act 4, it sits in a completely different portion of the market here than on its native US soil.

      As a 16 channel unit, the Act 4 is under $10k and it’s alleged the 20 channel unit will also be under $10k. When you look at the Datasat and Trinnov prices, you’re looking at a potential one third of the price of its competitors - you could argue the the Altitude 32 and Rs20i arnt even competitors..so i would conclude for US based consumers, the Act 4 is a much hotter proposition than it is here.

      I've heard this, but it was set up right in an open plan room and it was really good. If they ditch the touchscreen (seriously why?) and opt for something at Dirac level or above it will be great.

      It beat most of the Trinnov dems, but most people can't set a Trinnov up or are deaf.. or both.

      Hi Steve, first off great review and loads of fun reading it and cant wait for a final review with the darts systems as a Full HT Setup.

      Question is how does the Trinnov stand up against I would say its next best competitor the Lyngdorf MP-50 which come with the Room Perfect EQ and correction? And would you place the Acurus ACT 4 above the lyngdorf?

      Thank you for your time :)
