MC402 vs FPB 300cx

Take a look at Pass Labs amps. I run X250.5 with N803.
Can't complain.

Hey, there you go! Testing the amp out in your system is the only way to get a clear answer. Bear in mind that at this level, there aren't any bad amps - it is just that some will work better or worse with your system and tastes.

Sounds like you know what you like. That is good - many people rely on others' opinions to make their decisions. It is true that my JM Labs have more rounded bass than the 804s but they also have more of it and subjectively deeper too. It is the difference between convex bass drivers like the 804s' and concave ones like the 926s'. It also has to do with the surround design. The larger excursion drivers with the wide and round surrounds will always have more bass (though sometimes less tight) than those with small or pleated surrounds. I have noticed this several times. The latter types have a hard time getting the bass out into the room - this is the part I don't like about my 804s. The 926s on the other hand, have bass that comes out at you and kicks you in the chest with the right amp. That is my preference. Other speakers with tight bass like B&Ws (in my experience) are ProAcs, Monitor Audios and Triangles. You might want to look into the new 804S. It has a very similar style to the N804 but with a bigger sound and smoother top end. There are great chances you would really love this new version.

Keep us posted on your experience with the MC402. Be careful not to make snap judgements based on first impressions - it will be a very different type of sound than what you are used to.

If you want something better than 300cx go with a bigger Krell, either 700cx or older 600C or 350Mc monoblocks. Anything else will be different at best.

I would suggest staying with 300cx and trying a different preamp. KAV is ok but clearly a budget product. Simaudio P-5, Bryston BP26 or Pass X1 are much better and can be found for around 2-2.5k.

I have owned three FPBs and they really show shortcomings of associated gear. Once the rest is up to snuff your Krell will surprise you.

I had an MC-352 before going to a FBP-300C. The MC-352 was the predecessor to the MC-402, and the FPB-300C was the predecessor to the FPB-400CX, so it is bigger than the 300CX that you have.

I loved the 352, and it had loads of bass with my Legacy Focus 20/20s. The Krell too has tons of bass, but it seems a bit tighter to me. The Krell added a lot of detail without loosing the music IMHO - contrary to many Krell "haters" around here. With the Mac, I found myself listening mostly to small Jazz groups, but with the Krell, I found myself listening to all kinds of music, not just small groups. It isn’t nearly as soft sounding, but then I wouldn’t call my Krell hard either.

One nice thing that I noticed about the Mac though, it took little or no time to warm-up. The Krell is a different story. It takes at least 1/2 to really come around for me.

Either one is quite nice, but my preference is with the Krell. Since you have the Mac for demo, you are doing the right thing. Perception is reality here, and only you know what you’ll like. Be aware though, the Krell needs to be warmed up by playing music through it…just being turned on isn’t enough from my experience.

Best of luck!

First impressions...Not much time to post, sorry..Will catch up later.

Surprising Bass, exactly what I like. Much better than my current krell amp actually.

Mids are smooth and velvety.

Highs are detailed and airy.

I like this amp so far. More to come....
