I'm done with "home theater" and selling my 1508 and subwoofer. The Loxjie A30 replacing the Marantz sounds very audibly better - and I don't claim to have golden ears: I was floored at first how much better the miniature Chinese amp was: image, precision, separation, bass quality, timbres, etc. with lower power not being an issue at all in a medium-sized living room. It really is "can't stop listening" good. As to the DAC in the Marantz, I noticed early on a separate DAC sounded a lot better (I remarked here on this a couple years ago, and someone replied - understandably - that shouldn't be). I'm never buying an AVR again based on brand reputation. And the 15xx slim size, to me, is still much too large. I'm not sold on sound bars and Sonos-type systems. I hope traditional AVR manufacturers come up with some more imaginative, and better performing designs. Or maybe Topping, Loxjie, SMSL et al. will, before they do.
