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

:ksc75smile: :beyersmile: :rolling_eyes:

Walmart is owned by the Walton family. The richest family in the United States of America. Walmart is the world's largest company by revenue. If Hillary's system is from Walmart, you can be sure it's top notch. Coming to a Walmart store next summer - a niche division selling high end head-fi.

Holy moly this amp is huge for my already cramped desk!

Since this is my first tubes amp in decades, is it normal to have the tubes pin not completely pushed in? I was afraid to break the tubes in process? Kinda wobbly but it’s work.

It's a big amp but light. :) The tubes will go in fully. Just be careful. When removing I rock it gently to get it out. After a few times, it should go in and out a lot easier and it will go in all the way.

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.

Oblivion is indeed really powerful to drive ZMF. Low gain is much more than enough.

Sound wise, personally I prefer Oblivion than cayin ha300 mk2 when drive Verite Open and Atrium. More transparent, harder hitting, and bigger soundstage.

Hey guys, which new production, affordable KT88 tubes are the best? There's Shuguang, Gold Lion, JJ blue tube and Psvane although I'm not sure about the latter. @BzzzzzT mentioned about the Black Treasure KT88-Z which I believe are from Psvane. Are those your favorite and which have you tried?

Psvane KT88 Tii and Shuguang Black Treasure KT88-Z in that order.

Oblivion is more powerful than Studio Six and Wa22.

I'd rather not say too much. The Obli sounded a lot more 3 dimensional for sure. 🙈
I did get to hear OOR, with Hypsos power supply, at CanJam Chicago. One of the better SS amps IMO until you go well above it's price class. Nice small form factor too. Of course I have no frame of reference to compare it to UltraSonic Studios' masterful tube amps but I did like the Ferrum gear I heard at the show.

Lights off on a wintry night, I'm in Casablanca. With both amps driving Susvara so superbly, I'm very happy to have arrived at this stage of my audio journey. It's bliss.

Casablanca? Perhaps Humphrey Bogart was referring to one of @SonicTrance 's amps when he said "you played it for her, you can play it for me".

I have an open mind. If one day I get to try the OOR with the power supply, I would be willing to audition it. At the beginning of last year, I went through a number of solid states because I wanted to see if they are for me. The amps I've owned and tried in a 6 months period are Questyle CMA 12, Violectric V280, Auralic Taurus Mk2 and Schiit MJ2 (hybrid I guess). The first 3 are actually pretty good but I much prefer my Oblivion to them. So I sold them. Then came Odyssey and I've not heard anything else better to my ears. I'm open to try any challengers.

I believe the reviewer meant GEC KT88 and not vintage Mullard KT88. My personal take is that I agree with the reviewer. The Psvane is better than the Shuguang but the latter is still good. However the GEC KT88 is the best. No contest. It's gone back into the box and will make a once a year appearance at Christmas because it needs to be preserved. :wink:

Brimar CV 455 FB/KB (produced in 1956 !!! in the Footscray factory) and Shuguang Black Treasures KT88-Z. A combination that should pleased the fussiest of ears.
