Meo,
I chose the Pass Brand because after seeing Guttenbergs video of Nelson's
home I thought -If Pass uses Tannoys to voice his amps and I own Tannoys
the hard work is over. Gotta have Pass.
Meantime I hear Coda is supposed to be better. Never heard it.
As far as Luxman goes, I think they have upped their game in the last few years.
I never had both in my home to a/b. I did hear the $5k Lux Int paired with
Paradigm Founder $5k speakers in November. That was sound I could live with.
I hear your concerns about worrying over tube gear. Hum, wear. I had a Cary
120 amp and sold it to buy the Pass. Now I miss the tube sound so I may look into
the new ARC I-50 Integrated. Waiting for some legit reviews.
You might buy an XA 25 amp and see how you like it. Used they were selling at
$3k. To a/b you will need a to buy the Lux also.
Keep us posted please.
