To clarify, this happens when I first switch the unit on. Otherwise the volume is fine.

Sounds like you have a pair of imbalanced tubes.

Hey Guys,

We got more 6BF7 tubes in stock, these are great tubes for the CDM. The 6BF7 gives a very thick overtly emphasized "tube" sound, rich thick and powerful. Highly recommended.

Cheers,

Ken

Hello guys,

I m have a cdm n wa7/tp. I m thinking if I used cdm as a Dac n wa7 as an amp is it good ? Pls advise. Thks.

Btw is it normal to have static noise when turning the volume ?

I spent a good hour testing the CDM yesterday (from my AK380). Boy, it was a blast! Compared to the CV5, the CDM has a fuller sound, with more impact in its lows. I was so impressed that I actually bought one on the spot. Might consider tube rolling in the near future, but for the time being, the stock tubes are fantastic!

Completely agree! Not sure what to do with the CU amp anymore. ALO sells a short 2.5mm to 2.5mm TRRS cable just for this reason. There is a long DIY thread several pages back comparing some tube options that ALO doesn't sell. The cool thing is most of the tubes are really cheap at <$10 each. You just need to get the PCBs from ALO. I like the Telefunken 5719 tubes the best with Laylas.

Yeah, one thing I like about getting a tube amp is the ability to tweak its sound via tube rolling. Gives you more bang for the buck. After all, in the CDM's case, it is a pretty expensive amp. Still, with so many available tubes on the market, I can only wonder how it'll sound with a different set of tubes. Thanks for the tip - I'll be sure to read this thread in greater depth.

Maybe a naive question but if going from the single ended output to the balanced ended would that have any effect on the level of noise that may be coming through on my se 846?

Relatively speaking, the balanced out should have a lower noise floor since that is one of the benefits of a differential signal. However, in absolute terms I highly doubt there will be zero noise withe the SE846. Even with my Laylas in balanced, CDM has a very slight hiss.

New owner here of the alo cdm with a touch of paranoia.

Ive only had it for about a week - is a little bit of wiggle/movement when moving the vokume knob backwards and forwards expected amd nothing to worry about? Its moving with the board inside that is.

Any handy tricks to protect this protruding knob when packed away in a back pack?

Define "little" I can move the volume knob with PCB about 2 mm back and forth with firm force, but it is not loose. This is generally true for most pcb mounted volume knobs that are not physically mounted on the chassis. You will see there is no locking nut connecting the volume pot to the CDM chassis. It just so happens that CDM has the glass window where you can see the pcb move.

Thanks.

I guess its something like that. Theres a little but of give/movement if you push it. It doesn't move without a little but of force

I was only worried as when i first got i thought it was pretty much immovable (ie essentially rock solid) so i was worried something may have come a tad loose even inside the amp/board

My LG V20 doesn't recognises the CDM. Any fixes?

I have the same issue with my V10. There is a fix that ALO offers which involves strapping a couple of resistors on the PCB to improve the reliability of the connection. Here's the discussion
