I also agree with Larry. I heard a Conrad Johnson/Matiin logan set up, a Cayin 300B/Silverline Sonata set up, several Audio research set ups, I also had a KT88 chinese apm on demo, and all did not deliver classical very well. The CJ and Cayin offered orchestra as flat, very flat, worthless in fact. The Chinese KT88 amp was bloodless.
Though not all the above are set amps, in general when it comes to classical/orchestral/choral, tubes amps (Especially set) have one hell ofa time making it work. My Jadis Orch refer does produce sufficient fq's to bring out classical with some body. Mind you this is the smallest of Jadis, more in this case for classical would be better.
Note: my next amp will be the Cayin 845 monos/single 845 per block. Not the dual 845's per block!!!
btw I have the tube cayin17 cdp/ had the opamps changed and the tubes are Sovtek's grey plates/1970's/Upscale Audio. The Ops made a nice improvement, the Sov's made a nice improvement. I'm now going to change the caps to mid price Mundorf's.
For the money, this is a very nice cdp. The local tech guy doing the mods says he likes how Cayin has the unit designed. And justifies the money in the mods.
Bottom line, if you want full bodied orchestra, you need a a tube amp that can take on the complexity thrown at it.
Not sure if the 845 tube will deliver the goods either.
A true low watt set will not reproduce classical in a DYNAMIC manner. Dynamic = decent bass, decent highs(the Jadis is a tad weak in the highs, roll off) There I said it again just to be clear.
Good luck.
