The Aronov, I have heard are very good, also the AES amps, nevertheless, if it is possible, you should attempt to audition the integrateds I have refer to. Why? They do not have the tube swapping factor involved, as well as being rather small, original with a great jump factor. Currently my main rig is centered around the Final Music 5 and 6, amp and preamp, entirely battery powered with C and D batteries. I do not think I will change anything in my set up for the forceable future. The Shigaraki integrated amp, I have in a secondary system, but prior to that, it was my main amp for about 1 month....hadn't it been for a great offer that was made to me, I would have kept it there, but even now, it sings beautifully. It has the grunt to make medium efficiency speakers come alive but with high efficiency ones, you WILL be blown away. The midrange might not be SET like, but it is about 95%. I can attest to this, as I compared it with the 300Bs. The excitement with the pseudo midrange warmth of a SET. Check the reviews at 6moons. How Srabaen well said, "it out SETs a SET." The price I paid for it was around $1700 with a 10% discount. Nevertheless, if you go for it used, it can go for about $950. It is good for wait for a used one. I have not regret having purchased it as full price. I think it will be a glorious match to your Klipschs. I bet my money on it. The Decware, according to a Dagogo.com review, seem to be a little underpowered, even with the high efficiency Klipschhorn.
If you have any questions about this, drop me a line. I do not think there is a better amp out there, period.
Many full fledged audiophiles have gone the 47 Labs way. It is not that they do not have the means to acquire gear, they do, but there is something incredibly remarkable about the purity of its sonic execution.
Amazing.
