I own the A51 and an A23. Both are solid amps, great value. I have listened to the A21 and it is even nicer. I recently purchased the m700 mono amps for a new basement system. The M700's are a good value, but not as nice as the A-21. I have returned the M700's and the PS Audio BHK 250 is arriving next week! I also swapped in my Classe CA 2300 for the M700's and there was no comparison how much better the Classe was. That is why I am getting the BHK 250. Can't wait! The m700's are smooth and warm, but lack the detail, soundstage and clarity I am looking for. Ken

batman, unfortunately my speaker brand is not one that you can say the name and people will recognize. They are called Avance speakers, a Danish brand that is sold by dealers in 10 or 11 countries but not the U.S. I picked up mine a while ago from a Canadian shop when they were selling in Canada, but no more. They are two and 1/2 way with all scanspeak drivers, not unlike the Dana's on the attached but with one less driver. About 86 dB, 6 ohms nominal. http://www.avance-audio.dk/
fastfreight, thank you for your post. I did order the A21+ a few days ago and started reading about the M700's which I just became aware of. Having you provide hands on experience with both amps was right on. I did do my share of reading and did consider Luxman integrateds, Pass and a lot of other more "Audiophile Check the Boxes" amps, but right now wanted the Parasound. I have mentioned before I am two hours from an audio shop and just won't go in and test the amplifier at the store knowing I would be buying online.
It will be delivered next week and we will see how it goes, but I am sure I will like it. To whoever mentioned tubes, my preamplifier is tube (12AX7) based and I have had, and enjoyed, tube amplifiers in the past.
Thank you all for your kind input.
Just received my new A21+ and P6 preamp....
Hands down best sounding equipment for the money and even outperforms systems at twice price point.
Have had other high end amps... Krell FPB series, Pass X series, Levinson 333, Parasound JC-1’s.... and A21.... all were amazing.... completely satisfied with the job Parasound did with the + series. Quieter, channel separation better, just a more liquidy/? sound that draws me in... just has to be heard to appreciate.
Hi ribd11, I received my a21+ a month ago and agree regarding how it draws you into the music. I have an older pair of speakers that are 2 1/2 way with 7" scanspeak mid/woofers made in Denmark by a company named Avance. I have not posted remarks regarding how good it sounds because I really don't have the experience with other amps as you and others. I have used Museatex-Meitner mono blocks, Dynaco ST70 series one and series two, and most recently a Nuforce STA200. I have paired the amp with a very nice sounding Copland CTA305 preamp which uses 12ax7 tubes. There is just a rightness to the way my system sounds now.
I have PM you with a couple of questions.
I find this discussion very interesting. I have an old Parasound H2200 which is getting a little long in the tooth and may be in need of a refresh (It sounds good to me but I reently had a hum - not through the speakers that was resolved by tightening all the screws I could reach and the right channel positive output is fussy about how the speaker lead is inserted - banana ). It seems it is the predecessor to the A21. I am thinking to upgrade. I have a tube pre-amp and a pair of Magnepan 1.7i's
From a look the A21 seems to have similar specs but a cleaner layout (not so many caps strewn about the place) From the specs, the + adds about 25% more power,20% more uF (whatever that does for you) 50% reduction in THD at full power and small increase in signal to noise ratio.
I also have an opportunity to purchase 2 A21's (not plus) for 1380 each. I could use them as mono's or use them to bi-amp my Maggies.
I don't know I could use them as monos. My HCA2200 is not rated to drive a 4ohm load in bridged mode, if I remember correctly.
What say you?
