Sachin has yet to reply to my pm. Its like the kid in me is crying and wont shut up until he gets his k-buffer.

Okay then no issue, I was thinking what happened why you haven't replied back. Just give me a pm when you are back.

Folks, an update ...

Could not post impressions on the 25K volume pot due to the holidays. Now that the Christmas tree and decorations has been packed and stored, I have more room to change out gear in my setup. Placed the K Buffer in my chain this evening with the 25K pot and have been listening for some time now.

Bass response and transients are much better with the 25K pot. I also like that I can now turn the volume knob all the way up to 11 o clock and the loudness tracks the knob turn. Can go up more but with my amp 11:30 is plenty loud. On my setup the 25K pot is definitely the way to go. Thanks Josh and Omishra for the guidance.

Will post again after listening some more ...

Regards.

Which pot is this ?

Which pot is this ?

25K Alpha pot from DIYAudiocart.com

However some may prefer a higher quality volume pot.
I am considering the ALPS pot as a next step or something similar.

 

[saheb11123]

Blue velvet?
You can also save some and go for a stepped attenuator or a pot like tocos cosmos

 

[Nikhil]

Thanks for the recommendations.

Until this point I was trying to find the right impedance value for my K Buffer.
Now that I know 25K is the sweet spot I can start looking around.

Alps is a candidate and so are a few others.

Josh had recommended some options (page 23 & 24) ...

I wont trust aliexpress with my money.

 

[raj_krish]

Lol any bad experiences faced from aliexpress?

 

[avesbilal]

In my almost 50 transactions on aliexpress, except delayed shipping/long delivery time, I never faced any issues. I ordered 3 of these pots and looks decent quality.

 

[raj_krish]

I dint faced delay in shipping, but the shipping time will be more and max of 60days
Some products received in a month

is it recommended to use a volume pot of 10k/20k ohm with this buffer or can we use 45-50k ohm potentiometers also? Are there be any issues with it?

 

[saheb11123]

Technically you can use anyone even 100k too.

FM sachin uses 50k whereas FM nikhil found 25k to be better. So I guess you have to try it out yourself.

You may have to try and see in your setup.

I found that the volume control ran out of steam with the CITEC 32K pot that came with the kit i.e. no change in volume after the 10:30 - 11:00 o clock position (with 6:00 o clock being zero). Changed to 10K pot but the bass thinned out and was really not that good.

Currently the 25K pot is working just fine in my setup. Volume tracks the knob turn very nicely. Have not taken it past 12:00 as my amps are pretty loud.
