Fantastic monoblock amps from Dan Agostino with 20 amp IEC inlet. In pristine condition and barely used. These are phenomenal amplifiers with great control and power delivery. 
first owner of the monoblocks. I was experimenting with them in my system. As mentioned, they are in perfect condition. 
I think they were manufactured in late 2022. I have used them with solution amplifiers and a variety of speakers from Wilson to Bowers & Wilkins. They are very decent performers and have a strong drive. 
I used a variety of cables... had great success with Ansuz cabling in particular.
