    A51 vs. JC1?

    I am curious how close an A51 comes to the JC1 for stereo listening. I have 8 ohm/92 db speakers. Anybody get a chance to compare these amps head to head?

    I heard both and considered two jc1's because of the 10-25 watts of Class-A, but just didn't have 7k to dish out, I wound up getting the A21

    higher currant and wattage on the jc1, 92 db efficiency speakers will sound great with either, but at louder volumes the jc1 will win out. how do you plan to use the a51, since it's a 5 channel amp versus a jc1 which is a monoblock?

      Yes. I've used both the A51, A21, and JC1.

      The A51 was unable to deliver good power to my MG3.6s (4 ohms 85dB/1W) and clipped so bad that it blew a midrange fuse (OUCH!)

      The A21 is better in this respect, more power reserve etc. One thing I don't like about the A21 is the input attenuators. Most people don't need these, and it's just one more electromechanical thing that may go bad in time.

      The JC1s wins over the two by a wide margin. The JC1 can bottom out my speakers (MG3.6 and MG20.1) without the slightest hint of amplifier distortion. The JC1 has huge power reserves.

      In the end I went with 9 JC1s. I haven't looked back.

        why is the A21 so big?
        by tboooe
        Dont get me wrong, I love my A21. But compared to my old Rotel 1080, it is huge. Is the size difference due to the 50W per channel increase in power? Is it because the A21 uses the same chasis as the more powerful A51 and JC1 amps? Just curious why its so big.

        A51 and A21 amplifiers vs. A52 and A23
        by Chris D
        This is something I'm hung up on. Of course, I would love to have 7 JC-1 mono amps, one for each home theater channel, (talking 2 rear surround speakers, just to be clear) but just don't have the funds. In choosing whether to go with the A51 and A21 for a total of 7 channels, or the A52 and A23, it's...

        A21 vs A51
        by silverfox
        I am currently powering a Paradigm Studio v3. compliment (100s, CC570, ADP470s) using an A51. A good bit of my listening is 2-channel without a sub filler. I am thinking about potentially adding an A21 as dedicated amplification for the Studio 100s. All equipment is currently powered via 3 dedicated...

        I am a longtime lurker on this forum but now I have a couple of questions. I am the happy owner of a C1, A51, and A21. Originally I had them set up for a 7.1 system, but recently I have experimented with keeping the C1/A51 in a 5.1 system (partly for the negative WAF of the two "extra" speakers...

        Whats wrong with my Halo A21?
        by silverfox
        I've been enjoying my A21 tremendously for 2 channel music for the past couple of months until now.....

        I've suddenly begun to notice that the output from the right channel is significantly lower than the left. When the amp is first turned on and music played, the right channel is significantly...
