Mapman asked if there was one if there were any systems I would not be happy with from among the ones I have heard. To be honest, this is a great question too. I don't think I want to live with the PS Audio (I would always be thinking I could do better), or the ARC (though can't say why exactly — maybe it tries to do too many things all at once: amp, preamp, DAC, headphone amp). The Air Tight the shop had would not be sufficient to drive the Wilsons and they only bring in amps on order so that ruled that out. So that brings me back to the JR and VAC, where all of this started. If the JR and VAC Sigma were the only amps to choose from, I think I would go with the JR for ease of use and the 'weight' behind the sound (if that makes sense). The Sigma is really lovely, and though I haven't heard it with the (controversial) Wilson's, it lacks something by comparison. That is why I want to wait and hear the 200 IQ. And see if this is better. But JR for many reasons, some practical, is winning so far.
I did come across an amp that looks lovely though there is no dealer where I live. It is called Einstein. I have no idea about price or anything else, but it has a nice look to it. And since I don't have a 'woman-cave' -- the equipment is right in the main living space, aesthetics are also important. JR wins hands down over VAC on this one -- though those little orange glowy tubes are nice to look at!!!
I will listen to the Dvorak pieces. Very exciting.
