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---

Rogue has a new integrated amp callled "The Sphinx" It includes a MM phono stage which will accomodate high output MC's; headphone jack, balance control and.... 100RMS. All for $1295 retail.

One drawback is the remote control is extra $100 and only controls the volume. That to me sucks, and should be included in the price. I believe this amp is a hybrid. Check out their website.
Couple of good options: Moon is an excellent product, Ayre, one of the big Marantz integrated at your price point is a great amp, you may be able to purchase on of the new Luxman models on sale at your price, Musical Fidelity a great choice-have owned a few and always seem to be a top performer at their price,could also consider something from PrimaLuna if you want a taste of tubes.
