I'm pretty sure your question just broke my mind....Have any of you tried preamping the OTL into the Aegis? If so what are your thoughts?

Talking of Mullard… the ECC35 tall boys have turned up today. Listening to them now but to early to form any conclusions but. Definitely more about the mids I think compared to the RCA Red Base 5691s. Richer mids, touch warmer but still has good treble, smooth as you like with very good staging.
I think the 5691s are more dynamic but it’ll take a while to form a reliable feel to them and how I’ll use them.
They’re the La Radiotechnique EL39s.What are the two tubes in the back?
Surely one of the ZMF folks have both around and tried it?I'm pretty sure your question just broke my mind....
Listening to them now and they’re very nice sounding… smooth as you like. Very spacious. The 5691s are also very spacious but more like grabbing you by the collars and screaming listen to me man, let’s party… sort of dynamicsThat often seems to be how I feel about Mullard preamp tubes. I've no experience with the ECC35 so they may be different, but with the 9 pin minis I almost always prefer Amperex tubes to Mullards.
Power tubes and rectifiers are another story, however.
OTL can’t push the Caldera and isn’t as tube rolling friendly, Aegis can push all ZMF’s and you can tube roll to your heart’s content. Aegis was commercially available as of yesterday. That said, my VO on the OTL is one of the best experiences I’ve had with music. The Pendant is also very exceptional, especially with its tube upgrades. If the Aegis can be elevated by some tube rolling to the scale the Pendant did it’ll be a very, very high end TOTL amp.Away from subject of tubes for the Aegis......
I'm wondering how the Aegis would compare to the other TOTL hp, the Decware Reference ZMF OTL which is $700-$900 more. I'm both aware that the Decware unit is geared towards high-impedance headphones, like ZMF's, and that the commercial Aegis will be release very shortly.
Picked up some 6F6 and 6550 in addition to the EL33. 6F6 to test a real world bias point and recommend rectifiers if people want to use 6F6 / KT63. The 6550 I picked up for, err, research...reasons. Just doing my duty here.
So freaking excited for this amp. Tried at AXPONA and was blown away when paired with Caldera open. Anybody try the HEKSE with this amp? Great pairing? I’m looking for something that can really tame the highs. And I mean smooth as silk, as I’m particularly sensitive at 3.5-4 and 7.5-8 kHz. Can’t stand the HEKSE on solid state, though I need to try the new Prelude…
I had a couple of black plate Tungsol 6550s on loan for a while and thought they were great, one of my favorites.I'll be curious what you think of the 6550s.
Nice looking tubes! I almost picked up a pair of those 6550 yesterday, and am very curious about those. Also, I did score some Russian 6F6M1 53' Foton's yesterday, as well as some 6F6S (Russian KT63), and will wait to see which rectifiers to use with those. I also picked up a Osram U50 (5Y3G) cup getter rectifier, so I will have some good options.Picked up some 6F6 and 6550 in addition to the EL33. 6F6 to test a real world bias point and recommend rectifiers if people want to use 6F6 / KT63.

I still "need" to find and add a good 5U4 to the mix. . .
Cool!Nice! Yeah I'll let you know what the rectifier situation is. I also picked up this Sylvania hanging filament 5U4, an old military unit.
