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

Parasound A21 Stereo Power Amplifier; Black.

parasound A21 power amplifier and P3 pre amplifier. This combo is absolutely brilliant. The sound is amazing with loads of power. Comes with original remote, upgraded power lead and balanced cables and some really thick speaker cable (probably 1” thick easy ) it wasn’t cheep with terminals on both end but will only give away if full asking price is received. Cash or bacs only. Will demo no problem The only marks are on the power amp left hand grill at the rear . Only selling due to downsizing or I would keep. Pick up only due the the weight

Parasound CA215 2-Chanel Amplifier 15W/Chanel Tested and works fine with some tactic when turning the volume up and down. In fair cosmetic condition with scratches, some stains, some dust.

Parasound Halo A21 Power Amplifier - Black I have had this amp for a few years and has been used at most once every couple months to power my front channels. The amplifier has remained in my rack since purchased. There are very light scratches on a few of the fins from the initial placement of the amp in the rack, but is sonically perfect.
