Any reason I couldn’t use this Chineseium Stepped attenuator for my volume Pot? Any benefits?
-
If it fits the available space and mounting holes, it should work well. The measurable advantage is better channel balance. Subjectively it may sound slightly different, too.
That said, I expect there will be a version of our 2-stage switched attenuator for Moreplay out this year.
-
I’d much rather wait for yours! Thank you for the reply!
-
If I am reading the circuit diagram correctly the 10k volume pot is a 2W unit. Does it need that high a rating? It doesn't pass DC current, but I can't figure out what AC power it might need to dissipate. I ask because I'm considering stepped pot as well for mine.
-
There are ways to set up a Moreplay where that part cooks off some power. When I am bench testing amps and I need a lot of driving signal, I will run one channel of the first prototype Moreplay into the input of the second channel, and that could easily put 16V across that pot, but even then that's only 20mW.

Thank you Paul.

I know it’s only been a month. But any news on that Stepped attenuator? Lmao
-
What about a khozmo remote stepper? Maybe won't fit I guess?
It would be awesome if the manual had instructions of how to wire a remote pot. Even if its unofficial (on the forums).
-
The Khozmo remote attenuator is very, very deep. You could mount it on the front surface of the wood base possibly.
-
+1 for the Bottlehead Stepped Attenuation upgrade. ;D

Paul could we get some instructions on how to install a remote pot ?

This is one of those things that you'll have to figure out on your own, especially since it's something I've never done!

Paul,
Any update on the upgrade for Moreplay?Looking for a Christmas gift for myself.
-
IMO, don't let the upgrade hold you back from Moreplay. You never get back those days you missed out. :-*
-
My Moreplay is up and running with several of my own mods, just interested in what Botthead would do. I always considered the factory modifications more desirable.
-
Oh, I misunderstood and thought you didn't even have a Moreplay. My bad. I agree upgrades directly from Bottlehead will be the best one's.
-
I am working on something that is very much Moreplay related, but not exactly expected.

You are 100% right. I play mine at daily base.
I cant wait to see whats the upgrade will be.
Cheers from Fla.
Andre.

So we now need to wait for not only the potentiometer upgrade but something else aswel?
Any details ? :-)
-
If we shared detailsit wouldn't be unexpected,wuld it? :^)
Seriously, until we listen to a prototype there's nothing to say.

So I wanted to give a stepped attenuator a shot in the Moreplay because I was having issues with low volume combined with a Muzishare X7 KT88 amplifier setup to run as a power amplifier. It turns out I may have damaged the balance control on the Moreplay by trying to re-solder it (too many times probably) and made it unusable. So, I ordered one of those $30 10K ones from a US seller and wired the Moreplay to bypass the balance control. I actually decided to remove the control and wire in 100K resistors at the sockets.
After I measured everything, I hooked it up and was really happy with the result and perfect balance. The steps for both sides of the attenutor measured perfectly, so whoever made it did a great job with resistor matching. I have the luxury of having a prefect geometric near field speaker setup (Klipsch RF7 II). I've been trying out the KT88 amp for a while and the Streomour II was offline but put it back in the setup and all I could think was WOW, what a beautiful sounding setup. And it is NOT lacking in power and NOT bass shy nor bass quality shy. Anyone reporting thin sound, it's most likely the mastering of the media. The Stereomour II BRINGS IT! The Moreplay / Stereomour II (with Mourquiet) setup with stepped attenuators in both is just phenomenal. There are so many steps of control, there is no issue getting the volume to where it's perfect. The Stereomour hasn't needed to be moved off max volume yet, so all control is with Moreplay.
It's so good that I don't plan to return to the balance control. And I ordered one of those custom laser etched face plates (4x2 ... $10) to cover up the hole. I still plan to order the upgrade for the power improvements. I've learned with my other Bottlehead units that when upgrades are offered, just buy them because they always improve things. It won't hurt to have the Alps pots on hand in case I ever want to change back to a stock configuration. Anyway, I wanted to share the experience. My Bottlehead gear never ceases to entertain!

so I ordered a better Blue Dale 10K attenuator ($60) and surprisingly it showed up today (of all days ... Sunday). Anyway I measured it and the curve is quite a bit smoother and the switch is very nice. Resistor matching is absolutely perfect on both sides. I will install it soon. I added a graph comparing the two. Regardless of the measurement, the cheap one performs great too.
Edit: Installed. Perfect balance and imaging. Excellent low volume performance which is going to work great with my late night listening sessions. Very smooth transitions in volume. It seems like a better piece than the cheaper one, the clarity seems to be better, just a bit brighter in a very good way. The Stereomour II has never sounded better. It is incredible to say the least with these changes to the Moreplay.
I was lucky enough to order one of the Moreplay upgrade kits so looking forward to further improve performance.

Mucker can you share where you bought that Blue Dale?

Sure, a site called FYFaudio

Straight from China. It took just under 2 weeks to get here at my USA address. Tracking didn't kick in for about a week but after that everything went smooth. Used Paypal so no risk really.
I am not sure if this is the same people on eBay but it may very well be:

The eBay shipping cost wasn't that much a couple weeks ago. CRAZY.
The anti rotation pin slot needs to be dremeled out a bit (or the plastic pin cut off flush) for it to fit the top plate. I also had to chop off a 1/4 inch of the shaft for the knob to seat nicely. It's a really good performing attenuator IMO. Great with the SII and my X7.
