I believe there is substantial engineering that went into the AV10 and AV20, and the circuit boards are substantially different, while production numbers are substantially lower.Could someone kindly explain why the AV10 is $7k and a single ended AVR with as many channels from the same brand or semi-equivalent like Denon is about half the cost. Yes, they don't have balanced pre-outs, but they have the added cost of amplification. So what's the added cost in terms of parts for the AV10? And final terrible question, let's say the AV10 is going into a multi-channel Buckeye Purifi Class D amp. Will there be a discernable difference from said AVRs at 70db?
So there is some justification for higher pricing, however in the recent past, it was not unusual to see AVP's on the market using the exact same circuit boards as related AVR's (but excluding amplification circuits, and typically replacing the amp circuit boards with XLR output boards), and being priced at substantially more than their AVR cousins.
There has been a track record of claiming AVP's to be superior... most of which was debunked once people started looking closely at the circuits.
Having said that, the AV10 and AV20 are getting strong rave reviews, and bench tests are showing that their objective measured performance is excellent, and, I believe, superior to their AVR brethren.... whether that margin of improvement is in fact audible is a whole different question! and whether that improvement is worth the incremental cost is a value question that is highly individual to specific buyers!
For most people, the equivalent AVR's with the equivalent features and number of channels are far better value.
For those who have more specific amplification requirements, typically the higher amp needs are limited to the front L/R or L/C/R, and powering those externally, while using the internal amps for the less demanding surround and height channels, may still provides higher value/lower priced outcomes, without in any way compromising performance.
So yes, it is a valid question.
And for many of us, such components, at such a price, make no logical sense. (but value is always in the eye of the beholder...)
