Hello

Is there an idea of when the other upgrades will be released?

Thanks.

There is one additional upgrade, and we are collecting some parts for it currently and awaiting feedback on the first upgrade so we can perform any revisions that need to be made, then we will offer the second upgrade.

If it helps the current upgrade is fantastic.  Better bass and smoother sound.  Well worth it and highly recommended

Did you find any errors or discrepancies in the manual? 

(Speaking of, I need to put the second upgrade in my BeePre so I can work through that manual one more time!)

No, I did not find any errors in the manual that I recall.  I found the resistor bending instruction very well done and  accurate

Hi,
no error found in the manual either. The sound is more dynamic, more real, i love it!
Looking forward next upgrade too.
Thanks
David

I also love the first upgrade!  I found no errors in the manual. The improvements that I noticed were:
1. more bass definition/resolution and grip
2. a better composed midrange presentation. The fore, mid, and back-ground information is better balanced (vocals used to dominate a bit more).
3. a more holographic and 3D image, especially depth.

It’s really interesting that #2 and #3 can be true at the same time. Oh tubes…..

Sorry to hijack this thread but my question would have the same title.

I am part way through my Kaiju build and will be looking to move onto the BeePre2 next, ordering the Kaiju upgrade at the same time.
I take my time so this gives a few weeks (at least) of running stock Kaiju before doing that upgrade and then same with BeePre and its upgrades.

I intend to include the stepped attenuator upgrade so will order that at the same time as the BeePre and Kaiju upgrade but I am unclear what the final (imminent?) BeePre upgrade is.
I want to order all at the same time as there seems to be a small cost saving and I have to wait a few weeks for things to arrive in the UK.
Will be ready to order soon but am happy to wait for the final upgrade release.

Am not asking for a release date, just clarification on what the upgrade is so I can decide whether to wait or not.

Best
Chris

The final upgrade adds an individual hybrid shunt regulator for each channel to provide further isolation from the high voltage DC power supply.  Each channel also gets a buffered output and a balanced output is added.  Accomplishing all of this requires populating the 9 pin socket holes at the rear of the chassis and installing some dual dissimilar triodes.

Thank you Paul.
If pairing with the Kaiju, what benefit do the buffered and balanced outputs provide?

My limited understanding is that the buffer would help into low impedance amps (reference to this has been made on this forum also when discussing partnering with SS amps).
I also understood (perhaps incorrectly) that balanced output does not provide any benefit into unbalanced input.

The balanced outputs aren't particularly useful with the Kaiju, but they are not a substantial amount of work nor cost in the second upgrade.  The buffered output will more easily drive longer cables and will allow for more system flexibility if you wanted to add a powered subwoofer down the road, just as an example.   Some tube power amps with 12AX7 input stages also benefit from a stouter preamp output.

Thanks Paul.
Went back and re-read the 'in-depth' plus other threads and the pieces dropped into place (my understanding).
Low impedance into high is good, buffering lowers the output impedance providing a more robust output, especially for low impedance loads. Yes?
I had seen reference to plate amps elsewhere and the penny dropped with your comment about sub-woofers - still learning.

This gives me enough to make my decision on buy now or wait.
