Rob--
Dietz makes a good point-- "better" than what?
A few other things to keep in mind:
Duende and Liquid Mix both use FW. If you have FW drives, I'd also consider a serious FW PCI host, otherwise there may be regrets.
UAD-1 does have some very nice tools, and the recent Neve EQ has gotten some favorable reviews.
Here is a post from another forum which may shed some light:
@Other Forum said:
Well, do consider your needs because UAD-1 and Duende address different mix capabilities.
For example:
In addition to EQs and dynamics (comps), UAD-1 ships with modulation, reverb and amp sim plugs. Duende covers only EQ and dynamics.
Much of the UAD-1 is modeled after vintage rackmount gear (e.g., LA2A, Pultec, Fairchild, etc.), some dating back to the 60s. Duende is modeled after SSL console mixing tools, a newer toolset selection (the C200 to be exact -- not the 4000 like the Waves SSL plug).
UAD-1 operates via your computer's PCI buss. Duende operates via firewire 400.
Duende allows for 16 stereo plugins (32 mono) at 44.1kHz. UAD-1 plug usage depends on the type of plug used (i.e., some plugs are more processor-intensive than others).
LiquidMix: 32 Channels of Liquid Mix Compression AND 32 EQs run off Liquid Mix’s own DSP – many more than are possible with CPU alone.
UAD-1 is field-tested and developed to software version 4.3. Duende is new to market and only at software version 1.0.
Now, from what I've read in user posts, Duende sounds great and plays nicely with UAD-1, although SSL hasn't made any formal announcements to confirm this. You'd very likely benefit from having both tools. It's an option I'm weighing, in fact, although it'll be sometime before I can act on it.
Two things that have not been discussed: price and quality comparisons.
Clearly, UAD-1 is the greatest bargain and offers more, but will it do what you want?
Duende is pricey and does *less* that LM, but does it do enough for what you want? Are fewer features-- fewer channels the sacrifice for higher quality?
The only way to make sure that the quality of the results are to your liking is to hear them in action in person.
UAD-1: $500 USD +/-
Liquid Mix: $800 USD +/-
Duende: $1900 USD +/-
Does price equal quality?
Does quality come at the expense of compatibility or features?
Is money no object?
I've got UAD-1 and love it, but I've got my eye on one of the other two. LM has come in at a lower price than I expected, but regardless-- a PCI FW host is essential.
For me, I've decided that the price won't be a factor for the sake of quality. I want to go for the plugin that is most flattering to VSL-VI. I'm just looking for a vendor who has both and would be willing to let me test them for an hour or so.
