Nice upgrade! I had a chance years back to try a HiFi Tunning Silverstar fuse in my A21 and was smitten by the performance jump! To dismiss any notion of placebo , I first removed the main (critical link fuse) ceramic fuse on the A21 cleaned the ends with Caig deoxit ( buffed to a shine) and couldn't believe it . I later cleaned all the internal fuses as well as I wasn't going to replace them all, after that test I was convinced! it cost nothing and the Silverstar I added later at the $65 I paid was the cheapest system performance jump I've had.

If at the least polish the main fuse and tell me if I'm nuts or not

I just got off the phone with the reseller that carries b stock items from parasound and the jc2 bp i ordered (in silver to match my a21) was actually not a BP version and they said they will have a black jc2 bp in later this week but no silver with bp option yet. they are putting a call into parasound to double check before canceling my order.

now i am back to trying to decide if a the bp option is something i really need given i am going to be using my sr7009 for surround sound duties or if there is a logical way of hooking things up where i can use a jc 2 without bp for two channel with a21 and still utilize the a21 in my surround sound setup. Sounds like it would require physical switching each time...correct me if i am wrong anyone


I think, If I understand correctly, that the setup you are describing with your sr7009 for surround duties and still using the JC2 and A21 for 2 channel is exactly what the BP function if designed for. Give us a call and we can walk you through the JC2 BP and its Home Theater Bypass function.

Yes, that's exactly what the bypass feature is for. Getting the version without the bypass feature would require figuring out the correct volume level to set the JC2 to each time you want to send the home theater system through it and then remembering to switch the volume level back again when using other inputs. And keep in mind that the volume level for passing the home theater system through is most likely going to be high, so it requires some care when switching sources so you don't blow speakers (or eardrums). Finally, since the JC2 doesn't have a volume level display, it would be difficult to get it set to the exact same level each time which would make speaker level calibrations for the home theater system a bit of a problem.

So my advice is that if one has a need for the bypass feature, don't purchase the version of the JC2 that doesn't have it. The long term hassle isn't worth saving a few bucks.

I'm hoping the new 8802 has the same or better analog inputs when I get the upgrade bug again.
I do not know what advantage XLR may have over RCA except of noise cancelling in long cables. With 3ft cable I do not see a point. I saw HCA schematics and nothing there tells me that they can take advantage of XLR balanced input. I suspect they just turn it into unballanced input. Input diff amp's +in is used for signal and -in for feedback (negative therefore). +/- path from XLR will still go to +/- complementary amps but it is has nothing to do with noise/distortion cancelling. I remember Bryston hyped fully balanced path but not Parasound.

It still makes sense to have XLR in all components in case you need it. And XLR is no worse than RCA.

Regarding OPPO direct the one problem is that you have to digitally vary volume which means cutting out bits (reducing dynamic range). According to OPPO UK document it does not affect SQ but SQ is more art than science. Another problem is OPPO does not have standby pass-through mode. It means e.g. if you attach satelite TV box HDMI to OPPO and turn off OPPO - signal will not come out to TV. My SR6005 (and Emotiva UPC-200) have this feature and it is very convenient. And third issue is that OPPO does not handle analogue stereo input, more than 2 HDMI inputs and so on - but this does not concern me. But other two issues do.

My main reason for the Oppo 105 is 2/ch, I purchased both the 105 and 8801 at the same time coming from an Anthem avm 20v2 and Oppo 95 combo that I found to my liking and didn't want to sacrifice what I had. My main concern were the analog inputs on the 8801 as I love the sound of the Sabre dac's. As far as the rca's vs xlr's I always noted on most of the gear I've tried it was a better separation of instruments , taller center image and depth without sounding as though the music lost its flow. The rca's always sounded more analog if you will are had a warmer less forward sound but at the cost of a little snap ,this was of course after as close matching of the levels (and lowering the xlr's by one extra db for good measure). You'll have to forgive the use of the audiophile lingo as i have no other way to express why I prefer the balanced route. This could indeed and I suspect be due only to better noise rejection, long runs or not! most people don't realize the back of an equipment rack is an RF and nightmare
