I also have the Ref 20. Not sure if I want to upgrade or go straigh to the Ref 40. Only problem with upgrades is that although you get the same software as the newer version, the reale estate on the Ref 20 doesnt allow you to upgrade to component switching or other things like it
I have the ref 30 so the only thing I am missing is the balanced inputs which I don't care about anyway I purchased it used for the purpose of the upgrade because of the great deal I got on it. I just was wondering if the up grade was worth it.
I just got mine back and believe it is worth it-you get THX Ultra 2, music and cinema,DTS neo six, and PL 2. The sound is great and you have even greater flexibility with setting rear speakers and the sub. All and all a nice deal. You do not get a new face plate, but you do get cool blue lights that show it is a Ref 31 and a new Ref 31 manual. I think it is a very transpaent pre amp anyway and it is just as goods or better when you get it back with all the new surround options.
It is on the unit. When you power it up it says Ref 31. The display light was red but now is a cool blue. I think the question to ask your self is do you want the new surround options. If the answer is yes, by all means I think it is worth it. If you don't then it probably is not. I personally really like the ULTRA 2 surrounds because it makes better use of the 7 channel capabilities of the unit.
There is only one more component input on the B&K ref50 than the ref30 and as far as sound goes its the same DAC,s and processing in the upgrade so how they can sound difference has to be in the setup if they do
I believe they upgraded the DACs (not for sure just read it somewhere, B&K didn't mention it) but to be honest, I don't know whether I could tell the difference sonically when evaluating straight stereo anyway-but I am not a big believer that components that are well made with good parts would sound different so I would not upgrade for that reason. I would and did upgrade for the additional surround modes and the additional set-up options (THX 2 boundary, setting the rear speaker distance between speakers etc.)
I have not demoed the 50 but I doubt that for straight stereo I would tell a DBT difference. I think I could tell a difference based on the set-up options between dolby digital one for the other because there are things you can do with the 50 that you can't do with the 30. That being said, I don't know if they were set-up the same. I wouldn't have upgraded for that reason though. As I said, I upgraded for the additional surround modes.
That's good news, for folks in my situation where I want to spend around $1k for a used B&K Ref 30, and later upgrade as you have done. I love the ref 50 warm sound.. so if the 30 and 50 sound very close as others have also noted, then this is good news indeed.
Randybes what are the new options for the rear channels are you referring to and what about boundary confiscation how does it work? Also according to B&K yes the DAC's are the same as the ref50 hence they are new in the upgrade.
THX 2 makes use of the rear channels so it is not just on DD EX if you choose to use it. You now set the distance between your rear speakers. Please see the thread in audio theory on my question about boundary compensation. I think it compensates for a bass boost from normal rooms when using a THX sub or other sub that truely goes down to 20HZ but don't quote me on that
I've got the 307 also but have decided to hold off. I was so excited going from my ancient Denon AVR-2500 (DPL only) to DD 7.1 that this upgrade seemed to be only a nice to have, not a need to have. Perhaps when more movies make use of the back surrounds it will rank higher on my upgrade list. OTH, DPL II would be really nice for TV watching. (Click, Click, the sound of the 307 moving up the upgrade list )
