Wiim Ultra, Musician Pegasus R2R DAC, 3e Audio A5 amp

[vbutani]

Hi All,

I upgraded from Wiim Pro to Wiim Ultra and following is my setup:
Wiim Ultra > USB Hub(TP-Link UH400) > Seagate 4TB USB 3 External drive > USB out from Hub to Singxer SU-01 DDC > I2S in to Musician Pegasus R2R DAC > XLR in to 3e Audio A5 power amp (volume bypassed) > Dali Blue 6006 Floorstanding Speakers (Mogami 2804 speaker cables) > Sub out from Wiim Ultra to SVS SB1000 Pro

I am using 75Hz crossover to Main speakers, and bypassed sub crossover in Wiim Ultra and using svs subwoofer crossover and PEQ as suggested by Wiim Room correction.

Well your speakers go down to 40hz (theoretically, obv don't know the in room response) so why don't you just let them go full range and simply lower the crossover point to 40/45hz...ish (use your ears).
Btw nice setup

Because by high-pass filtering the main loudspeakers, you reduce intermodulation distortion for the Dali 6006s' 6.5" drivers, as well as improve headroom by reducing power load on the 3e A5.

Yep sorry, you are right, taking account the limits of this peculiar amplification, it makes perfectly sense. Generally speaking i prefer the "usual", at least to my knowledge, way: meaning full range speakers and completing the low frequency range with a good, fine tuned, subwoofer.

This was the "usual" way when stereo equipment did not provide proper bass management.

Today I tend to say that crossing higher is better with most all speakers.

I'm quite sure that hifi purists (eg Paul McGowan from PS Audio, just to name one) tend to have another opinion: hi passing speakers "generally" is not a good idea.
Personally i stick with it, but i support freedom of action

It wouldn't be the first thing Paul has an "interesting" take on. Especially when no reason is given, but devine experience.

Touché

Honestly i respect Paul McGowan a lot

Thanks! After trying several configurations, I settled on a 75Hz crossover for the mains because of limited space behind the wall. This setting has helped reduce the boominess in my medium-sized room. Without the Ultra, I would need to reposition the speakers for each listening session and consider room treatments.

I’m truly impressed with the Ultra’s features; it opens up numerous possibilities.

Do your room boundaries (walls) move around between listening sessions or something?

Oh that thing ...

Yes, he's actually right, passive line level frequency splitters do suck. The other part of his argument ("play it full range") is however totally unrelated. Following this idea, every 3-way speaker would have to run its midrange driver full range, down to its lower limit. Good luck with that approach.

Active crossovers and in particular digital filters give you so much more control, it's not even a comparison. Peter Lyngdorf knows this.

I don't claim here an absolute truth (OP is one example of that)...and as i already said i "support freedom of action", so i respect beliefs and experiences of others.

But i still like Paul's approach

Hope this could be said for the majority here. For now it's valid, but I see dark clouds

To be a fanboy or in my case a fangrandpa isn't automatically bad. The thing is to stand strong

"Obsessive about" is my second name But the time I did care about others are gone, at least for any hobby.

I think it's called "maturity"
