Edesilva: if you're riving two 200kOhm loads in parallel, the Delius is looking at an equivalent 100k load -- a very easy /trivial load for a 1ohm output Z device...
If you can set the delius to 6V output do so -- you might be feeding insufficient voltage into yr amps.
Generally speaking, with 1ohm output (more or less across the AF band, right? -- or is it 1ohm only at 1kHz?) you certainly don't need another pre (yr Delius already includes one pre)!
