Just brought home my new A21 and JC2. While burning in do I leave all components on while burning in and if I shut it off the power amp manually is that going to hurt it turning it on and off. I thought once its on you leave them powered up and dont touch.

If you want to burn them in quickly, leave them on all the time.
Otherwise, turn it off when not in use and save some energy.
I would say that the most important "rule" is to make sure the amp is completely warmed up (>30 min) before doing any critical listening...

Congrats on the new JC2 / A21!!!!!!Originally posted by Mike_Schmidt
Many folks use the Ayre/Cardas demag cd. The last track is about 285 seconds of a 5hz-20,000khz glide tone, just program the cd player for repeat, turn the volume down to low and let it go for a few days non-stop.

Yes it does, but you don't have to do it in a specific way. Just put a few hundred hours of playtime and the units are burned in. Leaving the units constantly on will take you there quicker, of course...Originally posted by Vince Helm
Personally I feel that a "normal use" break-in is better than using a test disk and leave it. In normal use you usually vary the volume a lot and use a lot of varying material. I'm not convinced it's a good idea to have the units run the same test tone over and over again at the same volume level.
When breaking in a car engine, you're supposed to vary the RPM the first 500 miles. I like the thought of adapting this and say that you need to vary the volume level and material the first few hundred hours...

Peter i have a question I turned my gain all the way to the left where before it was all the way clock wise on my JC2. My A21 was wide open to. So needless to say when listening to CD at 0900 on the JC2 volume knob it would scream but I turned my gain on my JC2 all the way off counter clock wise and...15 April 2010, 13:02 Thursday -
I have a Parasound A21 amp and JC2 preamp. I would like to place my A21 amp in the bottom shelf of my Sanus Euro rack. The rack is open on all sides but I only have 4.5" of clearance from the shelf above it. The A21 manual states "Leave at least 3” of space around both sides and 6” of... -
Hi,
I read a lot of reviews about Parasound gears and I'm considering the A21 power amplifier. I'm wondering about the pre-amplifier to associate to A21. In order to have the best synergy between the two components, I will also consider a Parasound pre-amplifier. Actually, there are two... -

i am burning in my new pre amp on my B&W 683's with the tara labs cascade burn in disk. I'd like to leave the system on for a week or so. can i put the boxes over the speakers to reduce the volume? will the sound waves within the box harm the speakers in anyway?
