You think that preamps in an AVR are no good?
You don't think.
Australian, mate. Act 1st, think second - unless you're releasing speakers into a very difficult market! Has the boss said what the target market is?
If the headphone amp in a Philips TV is indistinguishable from any other DAC/pre-amp then I guess the answer must be no, they don't matter that much.
I beg to differ inasmuch as the quality of audio from the analogue RCA outputs on my Panasonic TV are quite obviously inferior to the audio quality when the TV is connected to the hi-fi with an optical digital cable instead.
It also makes me wonder why the ADM9s have always employed such a good quality DAC/Pre when a 3.5mm - 3.5mm analogue cable - from a TV headphone socket - is 'indistinguishable' in quality. (Or am I missing something important here?)

Whether an AVR or a stereo amplifier, I don't think it's very good advice to say that any old pre amp will be effectively transparent.

On the contrary, I think you may have highlighted the dangers inherent in believing non-scientists who have something to sell.
If you need answers to technical queries or how the business is moving forward, you had best ask the people running the show. I'm sure that if you expressed a genuine interest, you might be furnished with a suitable response. Does the AVI forum not give you the answers you seek? That would be the logical place to air your thoughts.
I'm sure the target market would be similar to other active hifi speakers though and also for studio use. Price will doubtless be a factor in their success, just like any other product, but to assume that the competition is much cheaper active monitors, might as well be comparing a top line Audi saloon with a more mundane offering from say Hyundai and suggesting that the former is in any way some sort of competition.

I asked a similar question earlier. I suppose, in fairness, AVI never claimed the TV headphone out was as good as the AVI DAC/Pre, just indistinguishable from all conventional HiFi. So perhaps it is indistinguishable from just the audiofoo made by every other manufacturer.

My guess is that the quality of the analogue output would vary quite a lot between TV's. It's not something that I've ever tried myself though so I can't comment from experience (my TV is a heap of c**p anyway).
I have compared my (top of the range) Sony MP3 player to hifi quality DACs and pre-amps and it sounds indistinguishable to them to my ears. Considering this it doesn't seem all that far fetched that some TVs analogue output could be good enough quality to be indistinguishable to hifi DACs and pre-amps too.
But as I said I've never actually compared a TVs analogue output so I'm a bit sceptical about this too.

Pretty much any preamp (botched designs aside) should be nigh on transparent. They don't usually produce enough distortion to be audible in themselves. That aside, everyone uses a preamp of some description anyway, it's the first stage in the amplification chain, so you can imagine that there's quite a lot of choice so long as a preout is available.
If distortion is of concern, then there are plenty of choices for the more discerning.
My guess is that the quality of the analogue output would vary quite a lot between TV's.
Why is your guess that the quality of the analogue outputs would not vary quite a lot between AVRs?
Another case of the AVI lobby hijacking this forum. I actually think most of the AVI lobby should be banned from this forum.
Could you provide fully annotated references for you wild assertions, please.
No one has said that just any old pre amp will do.
But I'm pretty sure that the major large companies like Sony, Yamaha, Pioneer and Onkyo are capable of designing and implementing a DAC and pre-amp without there being enough distortion for it to make any audiable difference to the sound.
All of the pro-audio DACs and pre-amps from Roland, Behringer and TC Electronics that I've heard were all indistinguishable to each other and so was my old Yamaha RX-V667 AV receiver.
I disagree on both your points. This is a thread about an AVI product, started by a non-AVI owner, because it may be of interest to others. One might reasonably expect other AVI owners to have a view. Secondly, I'll leave the banning of those who are off-message to other forums...
I've listened to the analogue output of a couple AVRs (including my own cheap Yamaha RX-V667) and they sound identical to the analogue output of expensive pro-audio gear.
I can only guess about the quality of TVs analogue outputs because I've never compared them.
