I am no expert at all as i am looking at a new amp as the initial set up was not well thought out as i knew no better. Way too much research into this but.....ultimately know what direction you want to go with the speakers and what their requirements are to drive their best sound and get the amp that will pair with them as well as your ears, well.
I am leaning 190v as they should pair real nice with my MA silver 300's. Mind you i have been at this for months. No, i have no heard them with my speakers but have spoken to two who have as i have paired selections down.
I am running 100w at these speaker now and you can hear they want more as they have so much more to give, and i have heard it from them when i tested and bought them and can hear i am not getting that at home.
And..... still not 100% positive on the amp selection, but close (90%) as this offers a great headphone amp (which i use a lot) and a pretty good DAC that means i do not need to work on upgrades there for the short term and can focus on other upgrades and whn the time comes (if it does) i can upgrade the DAC and/or headphone amp..
I have no knowledge about the speakers you have but again, if you are upgrading in the future, and that upgrade gets you into a speaker needing more power that 75 wpc,, I would go 190V or an equivalent....otherwise 120
Oh, i looked at 390 (now 400)....and no need for me to have that 30%+ increase in cost for power i do not need now, and likely ever and that goes with a few other integrated amps i have been looking at.
Hmmm...so....i would say make sure you know what you will power in the future so you do not need to upgrade again for need. One can always upgrade for want.
