Been thinkin' about new MP40s

[gregzz4]

I've listened to some MP40s, and I have MP10s

The MP40s I've listened to lately are used, and over 1 or 1.5 years old. They are very noisy, at least to me

I have one more option to listen to an acquaintance's MP40 on the same size tank as mine
He has a 10 and a 40 on a 75g

We'll see what happens but, I'm not holding my breath anymore as I am finding the 40s to be too loud for my liking ......
