The Khozmo Mkii Stepped attenuator

[pankon]

I've asked Arek (Khozmo designer/builder) and he is very much fond of the shunt topology, claiming that it yields great (the best?) sonic results. Hmmm, what should I do?

I went for series as it presents a constant load.

That the the advice given from the guys here.

Panos, for the money try one of these before you do anything else, it's a giant killer :

Many thanks for the advice, Alan. It's just that I need a dual-mono passive preamp with two outputs. And as a matter of fact, earlier today I placed the order for a Khozmo preamp. My dilemma is shunt vs series resistors...
I will try to match and drive my Croft Series 7R monoblocks and Harbeth SHL5 Plus speakers.

Joe,

if I understand correctly, you just replaced your Alps Black Beauty pots with Khozmo's shunt attenuators? How easy was it? No other mods in your Croft preamp required?
I am also thinking of doing something similar to my Croft Micro 25 RSLS (Line-only) and replace the inexpensive TOCOS pots (https://www.ebay.com/itm/10pc-Cosmos...-/140413148908) with something more substantial (Khozmo shunt attenuators with z-foil and Takman REY or REX?).

I wonder if it's more complex than I think and not just a simple replacement of the pots... Thoughts, please?

The Superior stereo balance accuracy a good stepped attenuator acheives is; in itself IMHO worth the upgrade, However, I do understand why some would recomend some other types of conventional pots, they all have a sonic impact, you choose your poison etc.
As for Shunt, or Series, I have tried both over the years, and always come back to the Series type.
The khozmo Attenuators are exceptional value, with a build quality that is hard to beat at any price!
Hope this helps.

I'm sure Hificollective stopped stocking the TOCOS pots due to channel imbalances.

The Khozmo is a supreme attenuator, but you may have to reorganise the guts to fit it in. It's massive!

Yes, I am afraid the Khozmo attenuator will not fit in the Croft. I am wondering whether there is any other alternative attenuator (to replace the Tocos), that might significantly affect the sound (for the better -)).

I spoke with Glenn Croft about this when I was deciding on what preamp to go for. The Croft was a serious contender and I asked if he could fit a Khozmo. He said he could and would do so but never got back with a price so I went elsewhere. What I can say is, in my opinion, it's an absolutely wonderful attenuator and has far surpassed all of my expectations.

DACT attenuators will fit in the Croft, I have used these in my own preamps over the years with excelent results.
