More transparent, wider bandwidth, that sort of thing. The Viva brought out more of what was on the recording. We had a set of our M-60s on hand for that comparison as well.
If possible try to locate the ViVA Aurora “T” version of the Monoblocks. This is a special version with a pair of VT-4-C (211) for rectifiers, a VT-4-C (211) driver , 845 output tube, and superior transformers and irons. This is the ones that Lloyd Walker preferred and which I own.

No, I cannot. Never heard them with 845 rectifier tubes. If Bob at Profundo Audio is still around, reach out to him as he is the authority in the US when it comes to ViVA amplification.

both sounded like the Alexandria with some colour. One beautifying, one sterile. The CH with Stenheim sounded much better than both, and other SET based systems sounded better than all. So, you really need to match the amp to the speaker and have a good speaker
Its not the temperature, its the voltage. High voltage tubes, if subjected to high voltages, produce Xrays. Most are contained within the tube and at the voltages present with only 2000V or so, the production will be small. But some will escape the tube, since the plate has to be connected to the outside to get its voltage.

Again this is just my opinion but the Viva seemed easier to listen to, being more lifelike. One of the ways it did that was to be more pronounced in the bass. The speakers we used we still have and are not the best speaker for SETs. They are 93dB 1 Watt/1 meter and 16 Ohms. The latter part good, the former, not so much.
Ralph, have you heard the original Lamm ML2 with an easier speaker load say, 16 ohms and 105dB? I ask because I have read your posts which suggest such SET amplifiers sound best when using less than 10% of their power rating for lowest distortion.
