My New Don Sachs Model 2 Preamp Unboxing
« on: June 20, 2020, 11:53:10 AM »
Apparently, my audio addiction is alive and well because I now own two Model 2 preamps - at least for now. I may sell my older unit. My new Model 2 is in my system and burning in. It's up to about 4 hours now.  :X :beer:

I made a briefer post on AC and provided a link to this thread.

8 hours....

I should have my head examined for contemplating keeping both old and new...

Hi
Don Sachs here.   The new OLED display Khozmo has relay input switching.   The volume knob is also the input selector.  You turn the volume knob and it is a rotary encoder and will scroll up or down until it hits 00 or 63, the min and max volume of course.  You simply push the knob and for each push it will advance through the inputs until it hits 4 and then will cycle back to input 1.   One the remote you can of course increase or decrease volume, mute, cycle through the inputs, and there is a button to turn the display off if you like.  As with previous models, if you mute and unmute it comes back to the same volume setting of course, and when you turn the unit off it always comes up to 00 when you power it up again.  I have eliminated the channel attenuators because no one really needs a balance control, and the signal path is now VERY short.  The signal no longer needs to go from the rear panel to the front panel for switching and volume.  It only travels a few inches from input jacks to board and then a few inches down to the preamp itself.

Don

Since the units no longer have user adjustable gain what did you settle on for the fixed value?

It is still about 18 dB overall, but the taper on the Khozmo works well with most any amp or speakers.

Thanks Charles.  I will check in from time to time.  Kind of busy being a one man show though:)  Almost have my integrated amp done, but never seem to get to finishing it with production of other things having to take priority.

My preamp is up to approximately 50 hours now, and it's producing very nice music.  :thumb: I have not attempted to switch back and forth from old to new. Hell. They both sound wonderful.

Excellent product, Don!

wow the style changes on the new version look great.  Love that top plate and the socket color looks great.. and the new OLED screen with the colored text looks so modern compared to the old one.. I don't even see the oled advertised on hattor's own web site yet

Hi, uncola! Long time no chat.

My new pre is up to 60+ hours now. My system sounds so good that I haven't bothered switching over to my 'summertime' SS amp yet. The weather is going to have to get a lot hotter before I switch (even though the SS amp sounds pretty good). I love the magical music coming out of my speakers.

Hi all,
Just finished the new integrated amp.  The Valhalla.  35 watts/ch of 6L6 power.  OLED Khozmo up front, one XLR and 3 RCA inputs.  Fully regulated independent power supplies for each channel, just like the Kootenay amp.  Full auto bias of course.  I will post better photos on my site soon.   Sounds great for 5 hours and will improve for a week or two.
