Alright let's compare apples to apples. I've used EL81 in Ultimate many times but never as a side by side comparison with Oblivion. So here we go.

Ultimate - 6S3P, Siemens 6CJ6 (EL81), Tesla EZ81. Single Ended amp.
Oblivion - Marconi 6AV6, Siemens CV2721 (EL81). Balanced amp.

Now Ultimate soundstage opens up with the 6S3P and EL81 but Oblivion still sound more wide spread, deeper, higher. Tone wise they are more alike now and we're splitting hairs here but I have a slight preference with Oblivion on EL81 tubes. Both are gorgeous sounding.

Remember that Tomas chose EL81 specifically for Oblivion because he said the tube measures very linear. Likewise he chose EL36 for Citadel.

Both are incredibly good looking too. I've decided to lose the socket savers in Ultimate for this photoshoot.

Dimensions are almost the same.
Ultimate - 43 mm x 31 mm x 9 mm
Oblivion - 45 mm x 29 mm x 9 mm

Whoa!! Those are some tiny amps.

Ultimate coming in at 43 millimeters, that has got to be some sort of record!!

43 cm. Just to trick you into thinking it will fit easily on your desktop or the palm of your hand.

Ask Eric what he thinks of an amp using 6528/6336 tubes with 12AV7?

I did but he wasn’t very keen on 6336. However if a client ask for it I’m sure he can accommodate it.
