No experience with any of the others but I'm extremely happy with my AE3-DJH. The build quality is wonderful and I've been amazed at how transparently it responds to swapping tubes. Even upgrading the stock tube rectifier made a huge difference in the sound. It was exactly what I was looking for, three inputs, remote control, very high quality parts and a sound that opens up the music in a way I haven't ever had in any of my systems.
looking at some tube preamps,
Looking at the following:
1. Grounded Grid from Transcendentsound
2. The two Symphony and Symphony Plus from YS-Audio.
3. The Foreplay Extended III from Bottlehead
4. DIYHIFISupply preamp
5. Juicy Music Peach
6. AE3 or AE3JDH from Upscal Audio
The reason I picked these prees, is because the impedance is under 800 Ohms. I can adjust my amp's impedance so it likes the impedance it sees from the preamp.
Regards and happy listeming
