This thread is not a hack work or a diy attempt at re-engineering an already splendid design but a look at what may provide more listening pleasure.

In a sense the 4430-4435 appears a more simple concept, but beneath that simplicity lies a very sophisticated and elaborate design.

Go here for details:

So we are not going to mess around with the design but look at the more subtle and perhaps the not so obvious. As the saying goes, if it it ain't broke don't fix it.

Reading over a few posts by members who have bi amped the 4430-4435 it would seem that while they felt there were some gains they also felt that something was lost.

As discussed here:

I also found this when biamping the 4344-4345 and the findings can be read elsewhere in the 4343-4344 upgrade thread.

Its a case of not what you are doing but how you do it. The 4430-35 has stood the test of time but with the associated equipment things have moved on a bit.

The intention is to build a purpose built active crossover and amplifier and arrange for a member to trial it for a time and post their observations.

If you are interested post or send me a pm.
