That Woo Wa5le amp was shored up with the best tubes. Mullard CV1988 but we know Mullard didn't make those. They are most likely Brimars. Power tubes are Takatsuki 300b and rectifiers are EML 274b. I remembered that Woo amp as what I would love about a 300b amp... with those tubes. It was great. Mid centric, tubey as could be and a low end simmer to die for.
However I wish I could borrow that Woo amp again to compare with my Destiny now. Destiny is a 300b amp made by Eric of McChanson's amp. I am only using Genalex Gold Lion 300b tubes, drivers are GE 6EM7 and rectifier is a Sittard GZ34 Made in Holland. I have love Destiny for 3 months now. A love affair that is getting indecent. I spend so much time with LCD4 and Destiny in the last 3 months that I have almost forgotten about Oblivion.
So about 3 weeks ago I resurrected Oblivion again and started listening with my He1000se. This is when I sit up and wondered what I have been missing. My head's cleared now from last night lovely dinner and couple of craft beers. Sitting here for the last hour listening to music with these 2 combinations:-
Yggdrasil feeding :-
1. Oblivion > He1000se (Yang)
2. Destiny > LCD4 (Yin)
It's Yin and Yang. Yin is the black side and Yang is the white side. The relationship between Yin and Yang is often described as sunlight playing over a mountain and a valley. Listening to the same song with Yin and Yang and the contrast couldn't be greater but I'm transfixed by the tone of each. Amazingly beautiful texture. Yin is dark, warm and enveloping. The song 'I'll play the blues for you' by Daniel Castro seem tailor made for it. Yang on the other hand, is fresh, airy, details galore and an amazingly wide soundstage. After one and a half years with Oblivion, I still marveled at the instruments separation. Tube tone in Oblivion is just right and bass is present without being overpowering. With He1000se, I couldn't stop the listening session. I'm engrossed.
I love my setup now with my Yin and Yang. I wouldn't want to change anything but change is coming. Odyssey will be coming home and I've never waited for an amp with greater anticipation than this custom KT88 / EL34 tube amp (Odyssey) from Ultrasonic Studio.
There's the Yin and Yang in the rack.
I was about to press send to post this then I saw your question about which model to get for HD800S and Atticus. I've own Atticus before and I have the HD800 and have also heard the HD800S. Oblivion would be perfect for these headphones. That said, I've not heard the fully balanced Citadel but there has been some reviews of the Citadel in this thread that is very positive.
