Can't decide on Integrated Amp - Please Help

The MA speakers are very easy to drive, the Modwright KWI-200 is a fantastic IA( I owned one and upgraded to separates) and would be there through many speaker upgrades down the road. But for less money the Hegel 200 may be a better fit and is also well received.

Good Luck

Naim, Rega or Exposure. Very easy. All well below your price point.

Hi - my 2 cents. I bought a used Hegel 200 as backup for tube mono blocks. I've been very happy with it. It's got a pretty warm sound for solid state....
the upper frequencies are actually just a little rolled off compared to my tube gear, but possibly that's just in my system. Paid around $2500 for it, as I recall. Haven't regretted that choice. This is not to say any of your other candidates wouldn't make you very happy. Plinius was on my short list but I found the Hegel first. I wouldn't be inclined to spend more for just a built in DAC (didn't realize the 300 had one) but others have posted that the 300 beats the 200 on sonics. So if you can afford a used 300, that might be the way to go, though again I personally would not spend more for just a built in DAC since you already have a pretty good one in the the Oppo.

You might want to also consider a Plinius integrated amp as you had stated above. They make excellent products. I have owned several of their integrated amps and regular amps over the years. They are built extremely solid and have great sonics. I'm currently using the Plinius Reference SA amp in my main system and love it.
