Revamped archel 2. Better measuring more powerful.
Thanks. If one was just going to go unbalanced one would probably choose the Archel 2 GMR then as opposed to the 2.5 correct?
I suppose the counter argument is that Amir didn't ever test the GMR version right? So who knows if it introduced anything worse. Doesn't seem like it would but ...

I dont know the spec difference between the 2 GMR and the 2.5 but the 2.5 accepts XLR inputs of course. I would be surprised if you could tell the difference between the 2, the 2.5 and the GMR in listening to anything resembling "usual" headphones during playback.
I think the poster meant, what does "GMR" mean? that it is a revamped version is clear from the description on the Geshelli site.
The site is funny in that depending on how you navigate, you may or may not get a description of the product. I've now spent enough time on the site to know how to get to the descriptions. I've also emailed them with questions but no response in two days.

based on your recommendations, I am about to push the order button on a Geshelli Archel2.5X.
I like it as small as possible and I do love very small power bricks or power supplies built-in...
For me, I assume this Gashelli is better than SMSL SH-8S, SMSL SH-9, SMSL P200, Topping L50, SMSL U9, Schiit Magny Hersey, Atom, Zen Can Signature V2, or any in this price around USD 250.

How did you end up liking it? I just pulled my Archel2 Pro back out of its box to test my SMSL SU-8S, I haven't been using it the past couple years because I just use the THX 789!

You will need a relay R2R attenuator for that.
Any good ones on AliExxpress / eBay that you've used ?

I see no reason for using relay attenuators unless one wants to use a remote control or needs very small or calibrated steps and L-R balance in the extreme.
I only use RK27 pots, have been for over 35 years now and all of them work as fine as they did new and never had channel imbalance issues.
Great for volume control, nice feel and build quality and relatively cheap.

No channel imbalance issues at any position of the knob? Even 8 o'clock ?
Or needs to get past, say 10 o'clock for optimal channel tracking ?

The RK27 are fine. This is because the actual wiper tracks are quite long/large and there is very little 'play' in the wiper so easier to get it right.
In any case they are more than good enough for me.
When one were to measure a few (Amir style) I am sure some will have some deviations in the 'bottom' part of the adjustment range.
The used RK163 series is nowhere near that quality in many aspects.

With 'blue velvet' they mean the RK271 series. They are blue and the volume control is 'smooth' as velvet, as is the 'electrical noise' when adjusting the volume control.
RK271 simply is an affordable high quality potmeter, a bit bigger in size than most other ones and more expensive than the 'standard' lower budget RK163 series.
Of course there is always the RK501 series (but only 50k and 100k)

My amp has stopped working. This is the 2nd time this happened. First time it somehow fixed itself. I know it's the amp since I've changed sources and headphones. Pressing the mute button results in an audible click but I have no output.
