Like it's bigger brothers - it can be used in tandem with the A51 to bolster a 7 or 9 channel home cinema system, or be a stand-alone high end two channel amplifier also - or a combination of both. Big D Design I've got stereo junk in my trunk. The Parasound A 21+ offers a lot of low-distortion power and isn't fazed by impedances as low as 2 ohms.—John Atkinson. Editor's Note: Parasound specs this Additionally, Parasound’s A21 just won an Editors’ Choice Award in the March 2019 issue of The Absolute Sound magazine, which calls it “an excellent Class AB stereo transistor amp, designed by the redoubtable John Curl.” Conclusion: “The A21 offers a lot of power at an affordable price.” Impressive Performance Upgrades. numbers are weighed heavily with respect to the Ears validate the measurements, not the other way. But by the time he warned me, it was already a week to late. That's all I can offer (with included qualifications). - Parasound A21+ Excellent working order - a few scratches and scrapes on the front and top as per the photos, but doesn't affect the performance. The shape of the traces in figs.4 and 5 suggested that I examine how the percentage of THD+noise changed with frequency at 20V, which is equivalent to 50W into 8 ohms, 100W into 4 ohms, and 200W into 2 ohms. entire audio bandwidth. Add to Compare. The only problem that I had was with an AHB2 with the Monitor Audio Silver 8s in my CT system and I have not tried them with the monoblocs. Other Audioholics reviewers may rate products solely based on performance, If you say so. Me, personally? I had also tried several other USB cables such as AudioQuest Carbon and Diamond and Kimber Kable CU. I tested the Parasound Halo A 21+ with my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Shipping to United Kingdom. I will have to take a gander at my local dealer. It all depends where you have to spend your money. There is no headroom with the amp whatsoever, but it still does 200Wpc into 4 ohms, and the monoblocks close to 500Wpc. Parasound design consultant John Curl has been a legend among audiophiles and electronic engineers for decades. another $5,000, $10,000 or $20,000 dollar amp to compare the A 21 and A 51 In their eyes, that’s just a bad and rushed design. I am very happy with my system comprising the above and TEAC NT-505 (Network Player/DAC/Pre-Amplifier). The THD+N was very low in the midrange into 8, 4, and 2 ohms (fig.6) but rose at higher frequencies. One could also consider bi-amping the F228Be speakers with a ...

However, I would not hesitate to put them up against other amplifiers in I've owned a Parasound A21 for near three years now, also own a Parasound JC3+ and a Parasound 2125 amp in my shop driving 2 channel there. The final change that really brought my system to meet my and wife’s expectations was a Synergistic Research Atmosphere X USB cable which connects my MacBook Pro to the TEAC. Parasound needs to promote the designer that put the gold trim strip in the faceplate. For the amount of real power the A21+ is capable of, it stands stout. Slew Rate > 130 volts per microsecond. The A21+ results look worse (to my eyes) and also distortion seems to be higher than that of A21 in my measurements. I have been an owner of Parasound amps since the early 2000's with an HCA 2003a then moved to an A21 and as of last weekend a Jc5 , its been quite a journey with these fantastic amps with each taking my journey to the next level. tests at 1 watt into 8 ohms and found no excessive overshoot or ringing or slew After auditioning several amps both recently and over the years I decided to stay with the Parasound brand but jump into their Halo Series.
