Valab TDA1543 DAC VS MHDT Havana DAC

I will have to try some different tubes although the stock set-up is really nice. One of the reasons I am drawn to tubes is to be able to try a different 'flavor' when you get the itch. Is that the Tungsol 2C51 you are using or the 5670? Sounds like one to try - I've heard good things about the WE tubes too. Tried any others?

The Havana is still settling in and the highs are a bit 'steely' right now but it seems to be smoothing out quickly.

I have both.
The Havana is night and day better than the Valabs. It is very similar to the AN Sign 2.1 that I heard not long ago.
Huge detail and great resolution and extenion.
USB into the Havana is much, much better as well.
I use a WE 396a tube in the Havana. About $33 or so.
Very happy with the purchase.
Cheers

ps still love my Valabs - but rarely use it now.

mine is tungsol 2C51, I've got WE396a as well, I prefer the soundstage on tungsol.

I don't have the Havana. I just want to say, as a long time soldier for NOS, I am tickled to see the popularity of NOS grow as time goes by. Walk up all the way with the cool sound of NOS.

Karmatogdral,
Could you explain the difference in sound between the two tubes? I have been loving the WE396a but would like more soundstage in my system. Does the tungsol still have that amazing midrange?

Thanks,

Greg
