[UntilThen]

Wow Susvara is soaring with EL11 and 807 combo in UL mode. Radiotron 807 came back with me on yesterday's trip. So I have miss it for several months. If you love 6L6 tone, the 807 is it in a higher voltage. I still haven't heard Susvara on EL11 and EL12 spez. Many tube combinations to roll through. By the time I'm done, Susvara will be burned in.

I have just found a great tube combo for my Cossor 807. All of the 807 I’ve tried (Sylvania, Russian, Cossor/GEC) sound really good. And yes, that is coming from someone with a love of 6l6 tone.

Great sounding tubes and for the price good value. Susvara sounding nuanced and melodious with this tube combination of Telefunken EL11 and Radiotron 807.

The Cossor/GEC 807 with the MOV cv1102 makes deep, rich sounds in my system. Funnily enough my usual go to input tubes didn’t sound great. Must be the British connection that did the trick.

GEC is a revered brand. I have tubes with those stickers that sing like the sirens. Will win Eurovision for sure.

I'm getting a spectacular, astute and well rounded sound from my "Finyssey" with this combo. RCA 6FQ7 (6CG7) with E88CC (6N23P) adapter and perfectly matched and flawless Tesla EL12 Spez for output tubes. Vivid, crisp, clean sound that is also full, vibrant and heavy hitting and big soundstage. My favorite combo so far, even with this lowly setup with entry-level DAC and old HD-600 headphones (with silver cable and ferrite chokes to improve things), and this unassuming generic looking dirt cheap input tube. Still got more combinations to gradually try.

Can you describe the amp a little- three sockets? What are the functions of the meters?

Was wondering how would the oblivion do with zmf headphones like the verite. Very interested in it. However it seems like it have not enough power for zmf headphones

80mW into 300 ohms from the web spec seems pretty weak for 300ohms headphones

However it can power the susvara...... at 420mW into 50 ohms.

I don't know where you get that impression that Oblivion does not have enough power to drive ZMF headphones, in particular Verite. I should know because I have Verite LTD Open Pheasant wood for 2 years and I find it a very good match with Oblivion. Likewise the 300 ohms HD800 is perfect with Oblivion.

Of course now I'm very surprise that Oblivion drives Susvara satisfactorily.

Oh drives LCD-X and LCD-3f and LCD4 beautifully. I haven't come across any headphones that Oblivion cannot drive. Great pairing with my high efficiency He1000se. Wide soundstage, airy and crystal clear with the right touch of tube tone and no background noise.

Mr Curwen's design and he nail it.

Remember Oblivion is constant current source. Current always there when you need it. In reality you don't use 6 watts into any headphone. It's at most mw watts. Just need to have the current for the peaks in your music and Oblivion has that in abundance.

Oblivion is not your typical old school amp design. Read up Ultrasonic Studio website and get an idea of Oblivion design. I'm not one to understand technical stuff but my ears are my guide and I know what Oblivion is capable of. http://ultrasonicstudios.org/oblivion/

Thanks for the reply. I got the impression from the power ratings from the website. At 300ohms, 80mw just seems low when you read about it. Glad to hear that its powerful enough!

I'm now listening with HD800 (300 ohms) with Oblivion. My volume knob is at a 1/4 which is 9am. If I turn anymore my ears will get a blast.

Now for the surprise. Oblivion drives my speakers in nearfield listening. Hell Freezes Over has never sounded better.

This is Finyssey or Infinity v2 that takes it closer to the Odyssey. There's 5 sockets: 2 output and 3 input sockets (2 output tubes and either 1 6SN7 class or 2 6J5 class), but tube types is something that can be negotiated with the designer Tomas. I have one 'health meter' for each tube, which I believe is the best way, to help gauge any major drift before a tube goes bad. The two larger meters are for output, and the two smaller ones are for input (in the case of 1 dual triode 6SN7 class tube it works as one meter for each of the two triodes). The outputs are autio-bias and I manually adjust the cathode bias for input tubes with a multi-turn knob and Volt-o-meter according to a chart given by Tomas. Main description here.

Although my time with the original Infinity was limited, I hear an extravagant improvement in all areas of sound, IMHO, after the redesign which took it closer to the Odyssey. As such I can say @UntilThen is DEFINITELY onto something with the Odyssey, and that should be endgame material.

I like to kick the words 'endgame' into the ocean because with UntilThen there is no end. However I concede that I've ascended Mt Everest and the view is beautiful up here ! I wonder what system Edmund Hillary has?

I'm in bliss now with this setup. The Berlin tubes are amazing. I can't get enough of it. In fact many tube combinations are amazing in Odyssey. I will finish tube rolling in 2030.1

I asked Google which stereo system Edmund Hillary had, and they sent me to Walmart. (no, I am not making this up!)
