Wells Innamorata vs CODA 15.5??????????

I cannot speak on your speakers or the 15.5. But I do currently own and love my Coda CSi integrated amp. Runs my set of Tyler Acoustic Woodmere II speakers (hard to drive as well with their 4 ohm impedance). Could not be happier...The Coda does not disappoint in my house...see my system

FYI, I ran across one review that said the CODA 15.0 has 184,000 uf. The Salon 2s do need big power reserves to provide strong dynamics.

For what it's worth, (I've listened to Whispers, owned Helix and Focus, and owned Salon 1s, listened several times to Salon 2s) I'd buy the Whispers. They have a way of producing music that is just uncanny. The Salon's sound is what impresses audiophiles maybe music lovers not so much. Also while the Salons specs claim they go down to the 20s, (and I believe this to be true),it is a misrepresentation in a way, because they just don't move much air which to me became very frustrating. The Whispers present a holographic picture of the musical performance. While listening to them I have never noticed that they don't go down to subterranean levels sounding more like Magnepaplanars then cone speakers. They just get out of the way of the music and sound right. This is true of early models through today's current production.

As for Coda, you should call Doug Dale at Coda and speak with him about which of the Coda amps work well with Whisper. I believe they have a set there. I also own Coda amps (CS and CSX) (replaced now with TS I believe) which I know Bill Duddleston uses to design the entire Legacy line.

You might also give Mr. Duddleston a call at Legacy Audio. He likes to speak with potential customers.
You are more than welcome to contact me if you need more info.

Those Wells Audio amplifiers has got some mighty rave reports from the crew at Stereotimes.

The higher end amp, the Innamorata, uses Bybee music rails to filter the power feeding the input stage, which is where the signal is most delicate in a power amplifier.
