Mac 402 & Audio Research LS25MKl ?

I just bought the AR this last week. I like it, it is giving me so much more then I have had in the past.
The 402 is also very new to me. I do like what I am hearing but really would like to know what choices I may have for an improvement to my system.
My question: What amp is a better match for my AR? What really would I be gaining if I were to change?
I like the power of the 402.
My speakers are the Montana EPX. They are 4 Ohm. "these are keepers"
Thanks in advance for your input, it is greatly appreciated.

I am using the 6H23 NOS Type 2 from Upscale Audio in my LS25 MKI with excellent results.

Chiming in a little late here, but, I second Gmorris as I'm running the same tubes in my LS25 MKI, much better than the stock Sovteks. Other than the type 2 EH tubes from upscale, I haven't rolled any others. I don't know anything about the MAC 402, but if it's a truly balanced amp and your not using XLR cables between pre and amp, you should try it. Switching my system from SE to XLR, specifically between pre and my amps (JC1's) catapulted my system to another level entirely.

Seems to me that you have a heck of a good system. you didn,t described your room or your room treatment. But having that nice pieces of gear and not having attention as to the best in room acoustics would be a waste. I would have an acoustical expert or company like rives take a look at what can be done. BTW; While I have heard at a friends system the ls25 mk2 and its a very good sounding pre its disadvantage its that you are stock with the 6h30 tubes and no 6922 tube rolling if you go into that direction. Good luck on your descicion.
