HelloIm selling my mint condition Parasound A21+. Im the original owner and have purchased a different amplifier. I purchased this amplifier from Audio Advisor, and picked it up in person. I bought the amp in May of 2021. I really didnt start to listen to it on a weekly basis until November of 2021. I averaged about 12-15 hours a week, but at times not even firing it up for a week or two at a time. As you can see from the box, that I believe this amp was shipped via freight from the west coast and the box is in mint condition. One corner is dinged up, but these are boxed so good that it really amounted to nothing. I believe that the original condition of the box might be important to a potential buyer as this amp didnt get banged around (although they can take it) and really was in killer shape basically from Taiwan. I listen to 98 percent classical music and NEVER exceed 80db. I never could have listened louder if I wanted to. My room is pretty small. As Vilip has said from the YouTube channel (Audio Excellence Canada) if you have never heard something of this caliber, its a revelation. The A21+ is the deal of the century (not quite so much now that theyre $4000.00) but this amp really is killer. Great bass and great bass control, 6 watts of class A (if you listen at normal levels youll be in pure class A) very balanced in the frequencies, detailed highs. Airy and a sense of spatial information i.e venue. Ive taken very good care of this amp, and it should provide many years of great listening sessions. If you are coming from a bit of a distance, youre more than welcome to pick it up on a weekend. Keep in mind that you will have to buy a pre-amp. Really guys, if you are coming from say a $1000.00-$1500.00 amp you will be blown away. It is a neutral amplifier. If you have any questions, please feel free to reach out to me. Thank youDave

I will ship via USPS Ground Advantage in order to keep costs lower, one business day after payment. The amp will be double-boxed for safety. If you have questions, I will answer promptly. Thanks for looking!

Used in good working condition. Little to no cosmetic flaws.

Like New condition! I bought this brand new earlier this year, and used it for only about a month or so. Great sounding amp!! Stereophile magazine rated class A. But then I found a great deal on a Pass Labs amp, and have decided to let this one go. MSR $3,499 Asking $2,500 (Offers will be considered) Original Box and Shipping Materials — The outer box is a little rough but the inner box is in excellent condition with all styrofoam inserts to assure safe shipping.
