Please mind my English as it is not my mother language
I owe a pair of brand new B&W 800 Diamond which replaced my B&W 800 signature and the speakers are driving by GOLDMUND power and pre amps (over 10 years) with Redwine Isabella HPA as a DAC. The system sound is satisfactory however the weakness is the low bass.
I believe it is the right time to upgrade my DAC, I like Tube therefore I went to Redwine website and realized the products has now been replaced by LIO. Since it is now can play DSD and 32/384 file, with no doubt I immediately ordered a Deluxe version.
Two weeks ago it got delivered to my place in Australia and I had few days listening to its DAC part, the sound is astonishing which is well outperform my HPA even my Mytek 192, actually I believe they are really different levels.
Second stage, I connected my HD650 and have a listen, frankly speaking this is the first time I agreed that HD650 is a really good headphones , the sound quality is much better with LIO instead of Sennheiser's HDVA 800.
Yesterday, I tried the LIO's MOSFET amp and wondered whether it could drive my B&W 800 Diamond. After two hours listening to the system I would like to use one sentence to conclude "why I bother to revert back to my GOLDMUND amp system"
