No I would not think it was best practice, in fact I would say it is not but there are viable options though again not the "best" to be clear, imo. I just felt having the option to spend later on features/functionality when there is a need, may be better to some, obvious not all. With reference to the 4K HTP-1, if I am going to have just one such device, that would be my choice too over the Tide, but as I stated very early on, for some or many SINAD chasers, who value the highest attainable SINAD on the preamp/dac outputs, the Tide would likely be their choice if they don't really need HDMI 2.1 and more than 3 inputs yet, and the fact that there are plenty of external devices they could add on if and when they have the need for the 2.1 and more inputs make it a viable choice.
Best practice or not, that is not to say the Tide's V part is not a major disadvantage, of course it is. When the early D+M 3000/4000 series first launch, iirc, there was an issue with the HDMI2.1 section (don't remember the details), but they addressed it by sending the owners an external device (again, don't remember the details), and lots of people still went ahead with their purchases at the time. Even now, D+M still offers Dirac Live DLBC/ART a paid option only, some obviously wish they had included the licenses such that they would be ART ready out of the box but many, including me, would prefer it to remain a paid option, for the same reasons as I am using for the Tide's approach on not launched with HDMI 2.1 and rely on add-on devices.
"paid option" was just the term I used, I really meant external add on such as the often mentioned FD Fury products priced $249 to less than $500 depending on one's need. Such what I considered as paid option is something that imo, actually better in terms of being able to take the pay as yo go approach, so I don't have to spend on something that I may or may not ever use. Of course everyone has their own preference, and it is good that there are choices. By the way, I checked into the FD Fury Arcana products, they do have small foot prints, so the total space for the Tide 16 plus one of those FD Fury thing should still be less than that of a HTP-1.
I would of course, caution those who might want to go for the tide based on SINAD, Amir will likely be reviewing/measuring one soon enough, until we see the results, it better not to assume it would actually perform as good as miniDSP's claimed 118 dB at 4 V as published on their website. I might consider myself a SINAD chaser, but I don't believe 118 dB SINAD is audibly better than 100 or even 90 dB, not for me, but I am just attracted by such devices that perform so much better than others in that regard.
