Integrated amp to replace a MF Nu-vista M3?

I'd definitely do some listening before changing. What are you looking for with a change in amplification? A more substantial upgrade might be to go with separates.

I don't think you'll find any better integrated then a M3 Musical Fidelity. Definately in-home demo other products before selling your M3.

I heard your speaker with the plinius integrated
unbelievable.I almost bought those fidelio, that
time, I did not have the budget.Do yourself a
favor audition it.the cable they are using is
siltelch all the way.According to Joe Fratus
, He told me that the fidelio are the most coherent
speaker he heard.He uses them to evaluate his product.
He is the owner of art audio.This guy is sitting
beside me listening to this speakers.

Usually, a minor change elsewhere will reveal the magic. Do a Google Seacrh for 10 Secrets to Better Sound

I use a YBA Integre Passion to drive my Verity Fidelios... Before buying the amp, I tried a Nu Vista M3 with the Fidelio...

Very different sound... The Passion is more lean than the M3 but offers much, much more details. The Passion also offers a better soundstage and is much more transparent compared to the M3. The soundstage is also wider than the M3...

If you plan on playing music very loud, the Passion is not as powerfull as the M3 but delivers plenty of punch for a medium size room.

Overall, the 2 amps offer different value. The M3 offers big power for the buck but with less refinment. The Passion offers a good amount of power (100W into 8ohms) but mostly offers detail, transparency and musicallity.

You should have an in home audition before you buy... Taste is very personal but to me the Passion is a better integrated.

Also, you may want to consider an integrated from a company called Oasis. They have an integrated rated at something like 375W into 8 ohms. I cannot talk much about it since I did not audition the unit...
