This is the improved version of the original A23 Amplifier designed by John Curl. This update has many improvements over the original model including a 28% increase in power (125 watts to 160 watts @ 8 ohms), a larger transformer and gold on gold audio connections. I bought this amp to replace a Parasound 2125 v.2 and the difference was significant. Great definition and separation with no distortion, even when pushed. Ive upgraded speakers and Im looking for an amp with a little more power, which is why Im selling. The amp was stored in a cabinet with a glass door, so the casing has no marks, and it was protected from dust. Everything on the amp works flawlessly as it should. Original packaging included for safe shipping. Im quoting $120 for shipping, but that is to the farthest distance from me. If you are interested in this amp, let me know where you are located and I will re-quote shipping for you. Specs below. Thanks for looking!

Parasound A23 stereo amplifier, black, excellent condition, hardly used

Excellent condition A23. I got this amps from Rocnation (I work for them). The amps were at the old 1411 Broadway HQs and was in Jay-Zs personal conference room. Hardly used because hes rarely in his office. The amps were driving two pairs of USHER V-603 speakers. Great sounding amp as I tested them with no issues. Id keep the amps since Im a bit of a gear slut, but Im heavily invested in Crown amps and Im not willing to change my sound environment. Thanks for looking.

With an oversized, shielded toroidal transformer, and massive 40,000uF filter capacitors, the amplifier provides an unshakeable 125W RMS full-bandwidth into 8 ohms, with 225W into 4 ohms. The channels can also be bridged to provide up to 400W into one 8 ohm load. It is THX certified, with vanishingly low noise and distortion, and power bandwidth from 5Hz to 100kHz, ideal for hi-res content. The Parasound Halo series represents a combination of elegant circuit designs backed up with rigorous engineering and convenient design. The listed amplifier is in excellent cosmetic and functional condition. The item will be packaged securely in its original box and an IEC power cable (not original) will be included. Not all original documentation may be present. Two units are available with sequential serial numbers; same condition/quality. Price is for one, and only one amp (#6770) is pictured because they are virtually indistinguishable expect for the serial numbers. This one will ship first.
