Speaker or amplifer

@bigmac1963 -   If the seller has a trial period or will let you take the Hegel home, it would be worth it.  But more importantly, you are looking at a shift in preamp/amp technology, tube to solid state.  Will it be better?. That is a difficult question to answer, but it WILL be different.  So, if you can't demo the Hegel at home, do you have a friend, relative, local dealer, etc. that has something similar to the H400 that you could borrow just to see how a solid state system will affect the sound?  

- just my 2 cents...

Yes I can demo a hegel h 400 at home with my sonetto iii. I’m looking for more slam in my music.This my last upgrade for my system I like the sound of my tube amplifier. Feel like I’m missing something with this amplifier. I don’t know if a will get the sound from the sonetto v g2 with the amplifier I own.

I tested a Rogue and a Hegel amp, same speakers. The Hegel was the best amp I have ever heard, like I had my ears replaced. No idea about the SFs

Based on your described goals, I would definitely go with the Hegel H400 upgrade.  The Hegel will give you everything you desire and more!!!

That is great information on Hegel amplifier I will have to demo Hegel h400 with my sonetto iii speakers. I have heard the Hegel h400 with Sonus faber speakers.That was the best amplifier that I heard to my ears.What Hegel amplifier did you listen to with the sonetto iii.
