Lumin T2

Looks like I will have to start from scratch which is a pain because I have a large Playlist to create again, which I thought would load after saving it through the Lumin app.
Just hope the T2 will connect to my external HDD when I do.
I'm slowly sorting out the metadata of my albums and putting them on the Nas, but it's going to take ages to complete.
 
Other than the music from the old playlist, newly added music from NAS plays correctly right?

If not, please make sure Digital Audio Output is OFF in the current version of Lumin Android app.
 
This is possibly the world first review of Lumin T2, in Chinese:
https://post76.hk/thread-286039-1-1.html

The reviewer praised the dark background of T2. He also compared T2 against A1. He thinks T2 has a neutral sound, has better treble/bass extension, better tonal balance, and the voice is more engaging.

I thought the same :)

Google Translate does a terrible job of it unfortunately :(
Does anyone know of a better Chinese machine translation service? I tried systransoft but that is equally bad.
 
Cleared the playlist and have started adding albums to it again.
To the important part: What does it sound like?
Straight away: More detail and lower bass.
I'm sure I can feel it more than I did before.
It still needs a good few hours of use but the highs seem to be a bit too high from what I can remember, but hopefully that will settle down.
Early days but I don't know if it's producing a bit too much bass for my room now.
As I said, hopefully it will settle down after a few hours use.

Update: Bass notes do seem to be deeper. I'm sure I didn't feel bass in my chest like this before.

I think I was listening to Fink - "Perfect Darkness" from the live album "Wheels Turn Beneath My Feet" and it felt so alive, that bass drum kicked me right in the heart, it almost hurt... :)

Things might settle down, you might get used to it, or, as with all change to equipment you might need to re-position the speakers a bit.
 
@wklie
Does the T2 have to be used for a certain amount of time before it settles down?

I'm finding I have to have the sound lower than I did with the D1 with Sbooster.
Wonder if the Sbooster was smoothing the sound which allowed the volume to be higher?

Not sure if the sound is a bit too upfront (in your face).
Hopefully it will settle down if the T2 needs running in.
 
Playing this at the moment.
It does sound lovely.
If you like a bit of trumpet, this is a great album.

When upgrading from previous Lumin models to T2 or X1, it is absolutely normal to have to lower the preamp volume, because X1 and T2 output higher voltage than previous models - the voltage is now at approximately the same level as dCS and Chord. The increased voltage especially helps with the use of a passive preamp or a direct-to-amp setup.

Please let it play 7x24 for a few weeks in repeat mode, and turn off the power amp if it is not needed.

I'm wondering, what is the advantages of having a higher output voltage, and are there any disadvantages?
 
From the DAC side perspective, a higher voltage may have an advantage for SQ, but ultimately this depends on system gain matching. Without a higher voltage, some passive setup does not have enough volume for some music. With the same (approximate) voltage level as competitors, when you do A/B comparison the volume mismatch will be much less.

When listening, it reminds me of the 'loudness wars'.
I know, just reduce the volume.
I don't know if it was a good idea to raise the voltage.
Only time will tell.
 
The increased DAC voltage output cannot be compared to CD loudness war - the latter actually decreases the dynamic range, and the former increases it.
 
Hi Peter.
I see that the output voltage has risen from 4 Vrms to 6 V rms. But you do not publish the output impedance. You could say that value.
Regards

It said something about not being an official Roon ready device or something like that, but it's probably just a question of time as the product is brand new.

Please restart your Roon Core, and check whether the uncertified warning is gone.

For Lumin models without Lundahl transformers (T2 / D2 / D1), the XLR and RCA output impedances are a little above 20 ohm and 10 ohm roughly respectively.

For Lumin models with Lundahl transformers (X1 / S1 / A1 / T1), the XLR and RCA output impedances are 60 ohm and 40 ohm respectively.
