Parasound Halo A 52 5-Channel Power Amplifier - THX Ultra2 Certification Very Clean

Parasound Halo A 52 - 5-Channel Power Amplifier - THX Ultra2 Certification. Retail price - $2500 It was way underrated like all John Curls Halo Line of amps. Tested with actual output closer to the 180w just like the $3000 A52+ and they look identical other than the 1.5k VA encapsulated toroidal transformer. They should have built a top with a window to properly show off this superior amp quality and awesome build. Amp has always had an AC infinity temperature controlled fan on top and has never got more than warm during use. Adult owned, non-smoking home. Used sparingly in a dedicated home theater always at moderate levels. Amp is in very good condition with only lights signs of use. The case has a few slight “marks” and aluminum face has a few pin head size “marks” as well. Includes rack ears and installed SVS SoundPath Isolation feet for reduced vibration, increased isolation and stability over OEM feet. Overall in 9.5/10 condition. The Halo line is Parasounds top of the line cost no object line of amps, and it looks and sounds like it, Nothing compares to a Halo amp imo for value or a High class A Bias amp for sound stage and true Home Theater immersion. A Halo Class A/AB amp is not just a regular class AB amp, the High Class A Bias makes an awesome 5 channel HT Amp and even at low listening volumes is where Class A amps really shine, I think it is the first 20-25 watts are class A only and after that it turns into class AB with plenty of power!
