MHDT Orchid or Lampizator Amber 3?

Thanks @ghasley,
Can you provide me with a link to your tube source? Mine has no volume as I will use The Truth preamp with it. I will use the USB input fed by my Innuos server. Single ended only. 

Just got my Amber last week and am hosting a (two person) dac shootout this weekend.  The Amber, Audio Mirror T3-SE, iFi iDSD pro, & a Shiit my friend is bringing over (unsure of model #).  I've already had the iFi (and a Matrix X-Sabre Pro) for a few weeks... both will be going back.  Unfortunately haven't gotten to seriously listen to the Lampizator yet due to an unscheduled visit for all of MLK-day weekend.

How many play hours on the Amber by then? SR Orange fuse in it as I think the AM does?  Love the SR Orange fuses and ordered one for the Amber 3.  They sound wonderful in my upgraded Orchid dac! 

Looking forward to your comments! 

@grannyring Should be around 150...no fuse upgrades to either DAC yet (was not told that the AM had a boutique fuse and haven't checked).

@grannyring Brent Jesse www.audiotubes.com is a good place for NOS 12au7’s. Forthright to a fault, which is kinda important when you are buying tubes you may not even open for 10 or 15 years....the good news is you just need a really nice single with matched triodes rather than a matched pair with matched triodes.
