Thanks for your replies. Some not so.
What I ended up with for my Sonas Faber Olympica III speakers.
NAD C 658 Preamp with HDMI module.
Classe Amp 2 amp.
Velodyne HGS 10 sub. Had this unit.
LG 65 inch TV. Had this.
Logitech 665 Remote.
Arcam DVD/CD.
Raven Audio XLR's.
Audio Quest Cinnamon 48 HDMI cables.
Audio Quest Greyhound Sub cable.
Mogami speaker wire.
Speakers are Bi-Amped. Classe amp made for this.
System is for TV and music in our living room. Over all pleased with it.
I have had various equipment in the past but never the grade of what I have now. I have owned a few amps for surround sound(back to 2 channel) but older used equipment like an Outlaw 750.
I was thinking of changing amps to get a less forward sound was one reason. The other to just give the O'III's more power. I have experienced what more power can do.
From the salesman about switching amps,
Answering that really depends on your specific goals for
sound quality but overall I would say that yes, this is a significant upgrade
over the Classe unit. The Classe unit actually uses a class D output amplifier
which are known for being very dynamic and punchy, however they aren’t quite as smooth and fluid in the midrange.
The Musical Fidelity’s biggest advantage is not actually the
increase in raw power but actually the fact that it is capable pf producing
much more current which will not only help control the speakers better but it
will also give you a much more fluid sounding midrange. In this case the more
traditional design of the MF will be a better fit for your specific speakers.
Who would agree with salesman?
I believe I will hear a difference but is it worth the cost.
IMO amps do make a difference. Arguing about it is like arguing about what oil and filter to use in your vehicle.
