I have a first generation Glass FX tube DAC. For the money it is a pretty decent DAC. That being said, I have it at Jolida twice in the 2 1/2 years that I've had it. Once for a hum issue and once for a dead channel due to a cold solder joint. Jolida customer service is great. I would like to upgrade to a Glass FX III but I'm still waiting to hear more reviews on them. I do not intend to get the Bluetooth model as I use mine in conjunction with a Wadia 170i transport.
New Bluetooth Jolida Glass FX Tube DAC III W
My audio guy is ordering this http://www.jolida.com/product/glass-fx-tube-dac-iii-w for his fix-it guy tomorrow and I’m thinking about getting one. It’s so new that I’m not having luck finding reviews but I love that it has Bluetooth so I don’t have to run a cable from my iMac across a doorway (though there is a metal trim transition strip that wouldn’t make it stick out so much…I don’t think I can hide it underneath). My amp is a Cary SLI 80 Signature with KT 120s if that matters. Any opinions on this model or other suggestions?
