I wish I could say yes. I've thought active speakers with line level crossovers prior to the amps were so much better than how conventional passive speakers are done they should have taken over the market or at least had a large presence. It hasn't happened yet.
Beyond the inability of swapping components, there is the legit concern about what happens if one part goes bad years and years down the road. With conventional setups if the DAC goes bad I get another. If the amp goes out I get another. If the speaker blows up I get another or buy and replace the drivers. With something like this all in one unit should any part go out, I don't know how easily one can get it fixed, and will you be able 10 or more years down the road.
OTOH, I've some Tact gear which was an all combined DAC, preamp, power amp, and room correction unit. I used it for more than a decade. It still all works. I've moved on for other reasons, and the company is no longer in business. I received good value from the unit, and even versus current gear it is by no means embarrassed in regards to the quality of its function.
The 8C is by all accounts extraordinary. So there will be some customers. I just don't know if it will become a big hit. If I had to lay money on a bet, I'd say no. I think it has a good chance, but losing money is more costly than waiting and gaining a lesser amount down the road. I'd feel better about the company's chances if they had about 3 different models with two at lower cost than the 8C. Or if the company planned on that in the near future. I've no idea if they do or not. If I personally were about to spend money in or around the price of the 8C, I likely would buy them. They would be at the top of a very short list. Others on the list would be the Revels at a similar price, and the Kii Three. I'm sure I could add a couple more were I really about to purchase something in that price range.
