Berning TF-10 to TF-12. anyone do that?

I was wondering what kind of SQ improvement did you hear? The TF-12 besides the one that was listed this week here. almost never comes up for sale, as well as the TF-10

But I was pondering the benefits, given that the TF-12 goes for almost 2x the TF-10/
Very interesting news regarding a new Berning preamp. Having heard the ZH270 in my own system (and the MC40s but not the 60s), I don't think there's really a need to compare these two very different designs sonically. Let's just say that the ZH270 has very few peers from any era. I completely agree regarding Berning's design philosophy - I know of no other audio manufacturer who can say (with a straight face and uncrossed fingers) that the average life expectancy of the output tubes in their power amplifier is aproximately 10 years. I own both an EA2101 and two EA230 that I run as 60W monoblocks. I've never HAD to retube ANY of my Berning units (though tube-rolling in them is very illustrative and sometimes counter-intuitive...). Since I'm in Albany NY, the Montreal show is only a moderate drive away. If you have a link on the show, I'd be much obliged. Regards, -Richard
Palasar...What are the differences sonically between the Mc40's (which I also have) and the ZH270? actually can you tell me about EA 2101 and 230, compared to the MC40's?

I was pondering having an all Berning rig but cant afford the newer models.
Here is the link Richard. I hope to meet you there!
Tôi có 1 pre Berning TF12 khi để volume ở 79 nhưng vẫn phát tiếng chứ không hoàn toàn im lặng. Như vậy có phải lỗi kỹ thuật hay settup sai? Mong câu trả lời
Even at the lowest volume setting (79), the preamp doesn't completely mute.  Nothing is wrong with your unit.  To completely mute the unit, there is a mute button on the remote, but not on the front panel (mute will engage the small dots at the bottom of the volume display).
