I'm just going to say a few things here since I will be reviewing the Ref 6 and I have only listened to it for a few hours and it's far from broken in. First of all, even though the gain specs between the Ref 5SE and Ref 6 are identical, the Ref 6 seems like it has much more gain. The Ref 6 has a new volume pot which is smooth and continuous instead of the click, click, click that you have with the Ref 5SE in manual mode (not using the remote). The volume levels displayed on their respective screens can't be calibrated relative to one another because the same volume number displayed on the Ref 6 will be much louder than the same number on the Ref 5SE if that makes sense to you.
We all know that sometimes first impressions can be wrong and sometimes just because something stands out as being better means it might wear on your nerves over time as you become accustomed to what is going on. So here are some beans that I'm going to spill right here and now:
The Ref 6 compared to the Ref 5SE sounds much more powerful. If we put it in gearhead terms, it would be like going from a 327 ci Chevy engine to a 454 ci Chevy LS-6. If somebody would have blindfolded me last night and swapped out the Ref 5SE for the REF 6 but told me they replaced my Ref 75 with a big badass pair of monoblock amps, I would have believed them. It was like I didn't buy a new preamp, but rather I bought a whole new system. I simply wasn't prepared for that sort of difference. And trust me, I'm not trying to exaggerate one bit. And when I looked at the meters on the Ref 75 to see if they were still loafing, they were.
This should be a fun ride.
