When you have them open, side by side, many of the components they advert on the older larger BCP1 are simply not there, not to say the quality of what they used isn't good (they still advertise everything is top notch), its just different. I've A/B'd them and only had to turn the Jr. up to get the output in unison, so if theres a difference, I can't hear it. I can't confirm there is a switch to defeat the EQ and enable the 4.8 kHz hi-cut filter in the Jr. as well, as there is that option in your model (it is nice to completely remove the EQ circuit if you just want modeling from your preamp). Unless you're super stretched for space I'd keep the BCP1, I know I am.
