Zu Soul Superfly

>>Insensitive as in "not as critical" or insensitive as in irrelevant?<<

Meaning not critical, verging on not relevant. Large differences can have some effect but the design doesn't intend requirement for futzing with floor gap height. The Griewe scheme is now primarily internal via the cartridge and the finger vents on the bottom. You can find *some point* in the gap range where approaching no floor gap is not good but short of heading hard for zero, it should not be a critical factor. You need 1/4" gap or more. You'll notice in Zu's own photographs of the speakers, the spikes are quite tall.

>>Also I feel like presentation has been different higher vs. lower, though in fairness I didn't have it perfectly balanced when they were higher. I broke out the bubble level when I was working for the jewel case height.<<

Depending on many other acoustic factors you might be sensitive to differences in presentation associated with small changes in driver height. Or, as I said, if you head for zero on the floor gap less than 1/4", things will change. You may notice diffrences without having a clear idea which is actually better from a fidelity standpoint. No one can tell you what you're hearing isn't heard, but from a physics standpoint, Soul's design removes the floor gap from performance influence from 1/4" and taller.

gopher......The soul upgrade drivers will cost $400 after $200 back when I return my mk408 frd

the Duelund 10ohm resistors $40

as I live in Australia the the shipping cost is $1k and the upgrade to soul after selling Druids wld be another $1k..... I think I'll get 98% of what I want in the sound with the Frd upgrade. I acoustic damped the Druids boxes, upgraded hi pass for next to nothing ($200). As I mentioned before I have mini methods to help with bass...... Without which Druids would be lifeless in my room.

Worth a try anyway I think.....

Gopher,

Yes, the WC is a copy of the concept - probably Vinnie deserves the credit for that (almost certainly). It is an amp that gives a large portion of the same performance at around 15% of the price. For some, that is very appealing.

I found Zu varial and especially the Ash digital Ic to really open up the HF, compared to cardas and stereovox. I think as my pre and power amps are tubed maybe it was dark before?

For me it had more effect than changing amps?

Gopher: Phil does not believe that room impacts sound, especially in bass.

Therefore, he says that what you put your Souls on does not matter. It is "floor height insensitive' because it say so on the box.

In reality, put different speaker on carpet, wood, stone, you hear difference in bass.

Also, height of speaker can have impact on what you hear because super tweeter is very directional, and that impact tonal balance.

This is not about controlling gap height (which happen in druid) but about placement and room interaction effecting tone.
