switchable IV stages - IVYIII and Legato3
 
Hi

I don't want to start another thread on IVY vs Legato, I understand this is very much personal preference and I intend to buy both when they are available.

What I want to know is can I build a system that switches between them without having to pull everything apart each time. My problem is that any signal switching system would hugely increase the signal path length.

What I would like to know from someone who understands the curcuits better than I do; if I connected both the IVYIII and the Legato3 to a BuffaloII in parallel, but only powered one at a time, would the other (not powered) IV stage have a negative affect on the one I am using?

Thanks

Dan

Sorry but it is not at all practical to use both at the same time, even if you left one without power. For one the type of wiring you would have to do would likely swamp any other effect you wanted to catch.

You could run two DACs and A/B test, but I am not sure you want to go that far.

Thanks Russ

If I really can't decide which one I prefer or I want to use one for jazz and the other for rock, I'll just have to spring for another BII and all the other bits that go with it.

It's a win/win situation. Both outputs stages are excellent with anything you throw at them. :)

Ok, how's this for an idea for a new board once all your current revisions are shipping;

How about a half-half IVY / Legato I->V stage for (dual) mono buffalos? One side has one channel of an IVY, the other side has one channel of a Legato, with some switching in the middle for the input from all 8 channels of the Buffalo.

This would allow us to swap between the two linestages based on mood or the type of music we are playing without having the expense of two DACs.

Sorry, I am sure you mean well here, but this just is not going to happen. :)

Fair enough. I guess I'll just have to decide between them or spend more money duplicating the dacs and regulators.
