Default Unbalancer - user experience

I am reading about the unbalancer offered by Glassware Audio these days.
My purpose is to use with the opus DAC from TPA.
http://www.twistedpearaudio.com/digital/opus.aspx
What I am looking for is the tube warmth in my system and use the balanced output from opus board with unbalanced system .
I have heard a few complaining of hum issues.
Can I hear from people who are using an unbalancer or used to have one ?

Yes , Andrew. But I like to see if adding the unbalancer will bring in some tube warmth or analog quality .

You are looking for increasing 2nd harmonic distortion to audibility?

I think so, that is what tube sound is all about right? Sound was never digital to begin with

My understanding is that the Unbalancer is more suited to situations where you need I-to-V conversion AND bal-unbal conversion. If all you want is bala'nced to unbalanced with the 'taste' of tubes, as would be the case if you're using an Opus, this would be a better option.

If you want genuine 'tube sound' then the best way to get this is to buy a cheap Chinese 'tube buffer' off Ebay. Choose one with a very low supply rail voltage (say, 12V) and lots of blue LEDs lighting up the valves. You will get lots of 2nd, both harmonics and IM. Your non-technical friends will be impressed too.

Not I/V conversion in the first place, that is somehow a collateral effect when using low input R with high gain in the first stage. The Unbalancer is a BCF with an input stage providing gain. If you need that gain, use the Unbalancer. If you are ok with unity gain, go for BCF.
