Parasound Silver HALO Reference Series Balanced A-21 Amplifier Halo Reference Series like new (see attached pictures).

Overall it is in 8/10 condition or better but a small hard to see ding is there 3/4 the way up the outer side panel. Likely not possible to see at you seated listening position.  We have a second one coming in shortly that may be even better. but I would be proud to own it myself it a great sounding and in great shape.

Please note: we are authorized Parasound dealers and have opportunities on the new improved Halo A-21+ and looking for clients wanting to trade in and UPGRADE on their fine line of value packed Music L=overs & Audiophile products !
Weinhart Design's best selling amplifier "HALO A-21" in our history both at Weinhart Design & my old company Ambrosia Audio & Video and highly RECOMMENDED by us and virtually everyone in the know.

Now Parasound induced the newer version the Parasound A-21+ now300 watts stereo and $3,495. If your interested, it sounds even better and is adds 50 watts into 8 ohms making both the earlier A-21 at a lower cost and the newer improved + model a Stellar deal !

In excellent order but a small blemish on the face plate (see pictures resr of the condition exceeds 8/10 as new).

Comes in a Parasound A-21+ factory Box (essentially the same factory box.

If you are not working with a authorized Parasound dealer it is best to call David in Los Angeles for your best offer from Weinhart Design Inc. (we do not quote new items on line and after all we both have questions).

"This amazing group of equipment best demonstrates the audio industry's present state of the art."

SoundReproduction.com, October 2005

"Out of the box the A 21 sounds wonderful. I sampled several
Red Book CD's of different recording quality and musical genera's and
quickly came to the realization that the A 21 was indeed a very special
amplifier, and I could not wait to begin the serious evaluation after
burn-in." - Shane Mattson

Audioholics, December 2004

Product of the Year Award 2004 - Two-Channel Power Amplifier

"For those who desire the power of a Mack truck with the
finesse of a Mercedes Benz in a two-channel amplifier, look no further
than Parasound." "With the assortment of unbalanced and balanced inputs,
triggered output, and ground lift option no stones were left unturned
with this well built, attractive design."

Audioholics, October 2004

"The A 21 and A 51 amplifiers are both loaded with usable
features above and beyond most other amplifiers in today's market." "I
cranked the volume way up and found myself free of that inhibiting audio
alarm in my head that nags at me to turn it back down. Using the
Parasound amp allowed my speakers to portray every aspect that I had
come to expect without adding any noticeable sign of distortion or
flaw." "The Parasound Halo A 21 and A 51 are top rate amplifiers at a
great value. Parasound seems to have attended to every aspect of their
design including the excellent build quality internally and externally
matched with great looks." Overall Rating: 5/5 Stars - Ken Stein and
Steve Dellasala
