Looking for a very good integrated solid state amp


My system consists of:
Castle Stirling IIs,made by the original Castle firm in England, 91 db,
Rega Brio R integrated, Rega Dac, Musical Fidelity V Link 192, Atlas cable, Macbook Pro.
I love the Castles but I feel the amp should be of higher quality to get the fullest out of them.
My budget is $3,000 or so.
Anyone have any experience with:
Perreaux Audiant, Musical Fidelity M6I, Ayre AX7e, Linn Majk I, Sim Audio, etc.
Thank you very much---

It's all about synergy with your speakers. I have a creek destiny and a sim audio i5.3 and they are both great with the right speakers. The sim really works great with dynaudio but was a real bore with a set of Von schweikert monitors. The destiny sounds great with those same vs speakers but not as good as the sim on the dynaudios. I would ask the manufacturer of your speakers. Chances are they know what sounds good with them.
I am very satisfied with a BAT VK300xSE with the tubed front end. As mentioned by others synergy is most important. I have Acoustic Zen Adagios and first had a Wyred 4 Sound STI500 integrated and then an NAD M3. Both had terrific qualities and may have worked fine for another listener or speakers. You might have to try a few highly recommended and well reviewed amps before you find satisfaction. Good luck.
I love the Rega you are using but, if it's not good enough for you, try
Naim or Exposure.
