Using 2 integrateds to bi-amp?

Yes, use tape out on the Jolida. Tape out is "fixed" meaning regardless of where the volume is set on the Jolida the level coming out of the tape out is the same. This way it doesn't affect the volume on the other amp.

It will work fine and as you said no Y adapters needed. Let us know how it works out. Also, enjoy the flexibility of the two volume controls you'll have to make things sound to your liking.

If you want to be anal you can connect a tuner, tune it to "dead air" and measure the outputs of your amps with a voltmeter (set to AC) and tweak the volume control(s) to equal the output of each amp. You'll at least have somewhat of a reference for where each volume control is in relation to the other for equal output. In the end I still say set it the way you like it!

Electroid - Thank you very much for another good idea. Very helpful. If you celebrate Christmas, I hope it is a very merry one for you and your family. In any case, I wish you a healthy and prosperous New Year.

I did a similar setup for the Magnepan 3.5. I use the Jolida 1051 int amp 100W for Bass and it's tape output to a Opera EL34 40W tube int amp for treble.

Operation wise - you just turn up the treble volume first and adjust the bass to fit the song style.

Not the best sound one can get but it's workable and for the Magnepan this setup actually by-pass the passive pre-amp for the treble but added extra pre-amp stage. I would say it's about 80% of a good active bi-amp setup which I tried with a Lyngdorf.

Electroid, Jefftsefu et al -
Thanks for the input. Ran into some obstacles space-wise and speaker termination-wise so the experiment is on hold for now. Again, thanks for the helpful suggestions.
