Boazu upgrade cost, from version 1.1 to 1.3:

The approximate price in Sweden is SEK2500 incl VAT, plus shipping.
The approximate price in Europe is €250 incl VAT, plus shipping.
The approximate price in the US is $300.
The approximate price in the UK is presently unclear due to Brexit. :(

Hi!

I've noticed something. On my Bouzu if I only have the left channel cable connected to the left output on my bluray player
there's a hum in the speakers. If I connect that cable to the right output on the bluray player instead, the hum stops.
Also with both cables connected as normal there's no problem.

Do you think there's a ground/shield problem on the left output on my player or something else?
And is there something more I can check or do to troubleshoot this?

..but It's quite an old bluray-player and it's been tortured in the past with connecting and disconnecting super tight
Linn Silver cables so maybe I shouldn't be that suprised.

The way you describe it, it does sound like the ground is missing on the left output of your bluray player.

If you have a multimeter, you can measure the resistance between left and right grounds on the bluray player. If it's not close to zero ohms between them, the left one is likely broken.

Have you fixed the super tight Linn interconnects? You need to. Things do break when the RCA barrel is too tight.

Thanks for the answer!
Yes. It was the ground missing on the left channel. It was quite easy to repair though so everything is up and running again :)
And I did fix my Linn Interconnects last year but the damage was probably already done by then. I only happened to notice it yesterday.

Edit: Since this is a Boazu thread I'm going to ask, why is the upgrade skipping 1.2 and going directly to 1.3?

It didn't skip 1.2, there were two changes:

With 1.2 I finally found a surface mount resistor that sounds not just different but actually a little better than the through hole resistors I have been using before in this position. It wasn't an easy comparison and we did go back and forth many times before concluding that the new resistors were an overall musical improvement.

With 1.3 I replaced a capacitor by simply ordering a bunch of alternatives with identical specifications and listening to them all. Many sounded almost identical, but one stood out by sounding considerably more open and "alive".

These two changes were released together, because I feel they complement one another.

I kinda have the feeling that the Sagatun might use the same resistors and capacitor in their power supplies- is there reason for hope it also improves those ... and maybe other products?

That makes perfect sense. Thanks for the info and quick reply!

This might be the daftest ever question. Sorry, I am about to connect my subwoofer and just wanted to check the left and right orientation at the Boazu end.... Is left and right looking head on at the amp or at the back of the amp?

Hi Chris!

Before you connect your subwoofer, please read this carefully: https://www.lejonklou.com/tips/how-to-c ... -to-boazu/

Regarding left and right, the answer is that it depends on which side you have put the left inputs and on which side you have put the right.

The early Boazu had Left and Right printed on the rear. Later ones don't, they just have two sides and you pick one to be left and the other to be right.

I should perhaps return to the printed Left and Right, because you're not the only one who's asked.

Thank you. Good to know I am not alone:-)

Important to mention that it is in the process of braking in. From the beginning it has been softening more and more for the last four days. I should also mention that I have one more Boazu 1.1 which now sits in my second system and plays beautifully.
I have a lp12-lingo 4-kore-Aro-adikt-Gaio and a Linn krds-1 into Jern 14 ds speakers (wonderful musical Danish speakers). From the outset the two upgrades sounds quite musically better. It sounds clearer and have more precision. Interplay, shifts and elements is even easier to discern than before. It even feels more agile and tight and also as if it has more power(!). It could be that is not fully broken in yet and that these are to early conclusions, but this is my first take on the Boazu 1.3. Recommended!

Having now lived with the 1.3 for about a month I think the greatest difference from 1.1 is that 1.3 sounds a little tighter and ads precision. This gives greater insight into the musical piece. The tightness improves the temporal prat-thing. A little more engaging than earlier also.. The difference is quit apparent. Love playing music through it🎸

Thank you for the update, Fred11!

I just received a message from ThomasOK, who said I had seriously understated the improvement from 1.1 to 1.3.
So apparently he likes it too!
