Lumin, Leedh’ing the way

So, having a preamp this feature is not working at all?
Or, I can set my preamp for example to "middle.position" and then I can use the Leedh volume control?

Thanks.

Peter, Thank You for making this happen!

Putting together a second system just became far more affordable.

I have a late-90's vintage Wadia CD player that for years was connected directly to my power amp. There are 4 internal switches that you use to change the output voltage. I found the setting that worked best in my room and allowed the Wadia's volume control to operate in the top ¼ or so. Sounded great.

Now this Leedh volume control will allow a Lumin to go directly to a power amp as well. Even better, though - adjusting the max. volume is done right in the app, no need to open the unit up. Very slick! And from what I've been reading, it appears that there won't be any sound degradation at all no matter what the volume.

This could be a SERIOUS game-changer.

Listened last night on my S1 and was very impressed with the more natural sound...not that it was bad before....just incredible now.My system does not have a preamp as my S1 goes right into my Grail SET mono blocks.Thanks Peter for another amazing Lumin upgrade...

Good point, Calloway. I suppose those Lumins are probably going straight to power amps in more cases than I would have thought.

Looking forward to hearing more impressions of the Leedh sound difference from users with that setup.

Yes. You can turn down the Lumin volume, then set the preamp to unity gain position. If it's not clear what position is unity gain, see if you can determine that experimentally (with care).

After I decrease the volume or even mute no changes in volume, same sound.

Please use the latest Lumin app to disable Volume Control, then enable it again. Make sure Custom Re-sampling is turned off.

When playing music from the Lumin app playlist, reduce volume should cause the U1 MINI USB output volume to be reduced.

Alternatively, you can also try Linn Kazoo app for volume adjustment.
 
Re: Leedh Processing Volume free upgrade

I'm still not sure how this works.
I use a Music First Audio Baby Reference V2 passive pre-amp.
Does this new feature work when connected to a passive pre-amp?

You can choose whether to use it or not.

Scenario 1: You set LUMIN T2 volume to 100%. Use your pre-amp volume. This would completely ignore the new feature - which is fine.

Scenario 2: You adjust volume with LUMIN, set your pre-amp to unity gain (you could probably find out from the manufacturer what this is) and leave it there. In this case you would be using the new Leedh Volume Control in LUMIN.

Scenario 3: You connect LUMIN T2 directly to your power amp, bypassing the pre-amp. In this case you would be using the new Leedh Volume Control in LUMIN.

So it really depends on how much you want to experiment or if you are happy with the status quo.

Edit: Although I see you have multiple sources, which makes Option 2 a little unnatural (resetting the pre-amp volume whenever listening to LUMIN) and Option 3 very limiting.
 
If you would like to try Scenario 2, enable the Lumin Volume Control and Leedh Processing Volume, decrease the Lumin app volume first. Then on the Music First Audio Baby Reference V2, increase the volume to 0dB.

Most of the volume range in Lumin T2 has roughly 0.5dB step. Depending on which variant of the preamp you purchased, you may have 2dB step in your preamp. If this is true, each attenuation step in preamp corresponds to 4 steps in Lumin T2. You may also use a free sound meter app on smartphone to make sure the volume level between the preamp volume (with Lumin volume set to 100) and the Lumin volume (with preamp volume set to 0dB) is similar for A/B testing of SQ.
 
I am currently using a preamp that has two rca outputs.
One for the main stereo amp and the second set for my subs.
If I tried scenario 3, are both the XLR's and RCA's simultaneously usable on the Lumin?

Hi Peter, I disabled and enabled volume control, resampling is off. Still no effect when volume is reduced in the Lumin app, same for the Linn Kazoo app, both Android.

Additionally tried with the Kazoo Windows app, does also not work. What I do see is when volume is set to 70 or so in one app - like Kazoo, I do see it is adjusted in the other app like the Lumin app.
 
Does anyone have thoughts about where we are in the X1 product lifecycle?....beginning...middle...getting ready to replace?

From a historical perspective, probably somewhere around the middle. From what I can tell, the previous top of the line S1 was announced 2014. The X1 was announced 2018. Lumin might choose to come out with a new top at a higher price and continue to sell the X1 as a current model, somewhat like they did with the A1. From that perspective you might think of it more toward the front of a product cycle with a long tail. Enhancements like Leedh tend to lead one in the direction of a longer life cycle.
 
I suspect that whatever replaces the X1 will only be marginally better. The X1 is only slightly, but obviously, better than the S1, so it seems we are nearing the top of digital reproduction.

X1 will remain to be our flagship for a long time. I guess it would be like this for a longer time than the period when S1 was our flagship.

We may already have the best ES9038PRO design in the market, since there are X1 customers who also have and compared X1 with other ES9038PRO DAC from famous brands.

By the way, we're not doing a 0.1 hardware version increment and call it a new flagship.

If you're using Lumin A1 (or T1 or S1 or X1) connecting both XLR and RCA simultaneously will degrade the sound quality.

In the Lumin app About function of U1 MINI, you can tap and hold the Factory Reset. Please try it. On boot up, enable volume control again, and check the volume function.

Are you using the USB Output of U1 MINI, without any other output connected?

Does pause in Lumin app work?

Please post a screen capture of the Lumin app About of U1 MINI.

First of all, thanks for your support!
I did the factory reset and enabled volume control again. Still no volume control via USB out (Oppo UDP 205 connected on Lumin U1 Minu USB 1). I also tried via coax connection, and hey, Lumin connected via coax and now the volume control does work. Back to USB and volume control does not work again. Any other ideas?

- yes only one output connected at the same time
- song pause does work, mute does not via USB out (it does via coax)
- screen caps;
