thanks. 700w on the ADs help w/ some details and dynamics, easily hearable with timpani drums.
i live down in sanjose area.

did a thing. put a little double-sided tape to help hold it in place. also did a little silicone caulk to ensure the wire opening's closed up.
had to pull the rear valance, ran the wire over to a gasket for license plate lights. bottom of the camera's view is my bumper edge so yay.
also had to pull the hatch apart to run wire and ground(s). here's under the beauty panels, i couldn't imagine also trying to squeeze line drivers in there:

so i spent 45 minutes with it outside. different devices, same app, same flac 16b/44k content. i did the best i could to match levels by ear.
really i suppose comparing the sony's DAC+sony's opamps+helix ADC+helix DAC vs the helix's DAC.
i used meca's kirnis/spring and taylor/baker street. also used lindsey stirling's we found love on apple music. here's my observations:
d10:
- chimes and triangle in baker street are more articulate
- shaker on we found love more articulate
- better dynamics on cellos in spring
- better vocals in baker street and we found love
no staging differences, no low frequency differences.
i'm sure if i had measuring equipment, i'd see the differences and these observations would make sense

Based on what you've posted it seems like it's kind of a coin toss overall between the two. If so, it would come down to ergonomics for me. While all these fancy DACs, DAPs, and hugs are neat they are just too cumbersome for me. Especially when driving. Demoing someone's car is one thing but driving down the road trying to find a song on a 3 inch screen is something else altogether. If the two methods are a wash then I say go with the Sony. So, there's my unsolicited $0.02.

daily, the director+d10 is rough. i've been using the sony 100% since i installed it. this is the first day i thought to compare them.

i made a change, swapped out the helix pro mk2+director for an arc audio ps8pro+psc. why?
* ps8pro sounds better
* ps8pro lower floor noise
* hate the director
i wanted to put it where the helix was. i had an idea: cut up an arc x2 shell to look like the amps and shaped like the helix dsp.
ps8pro had to fit vertically:
got some bits:
open up the X2 hole to support the ps8pro's LED plate:
cut up the x2 plate to match the helix pro mk2 shape, got it placed and centered. that sucked but ignore the fingerprints:
i turned my attention to the director to psc replacement.
worked with kwilliams312 to CNC'd an aluminum adapter from 1/4" sheet:
had to cut it twice
a little sanding:
and it's in place:
"what about 10 channels with rearfill?" probably minidsp 2x4. for now rearfill's just off (like always)

How do you compare the R3004 to the standard silk dome D3004/6020 ? I've never been clear on the advantages of ring radiator tweeters.
I love the lead sheet idea. Pods look excellent. The whole install looks excellent.
Any thoughts on why you don't like the rear fill ?
You drove 5600 miles round trip for audio competition ? Holy crap. I would have been tired of the whole hobby by the time I got there.

i haven't compared them to the d3004s, but tweeters are mostly on-axis so i went with the RRs for extension.
rear fill is hard to get right so until i have time to play, i just leave it off. here's a couple other comments i made about it:

i spent some time with a hot water extractor the other week.
black/charcoal interior hides a lot. this is from a floormat:

also remade my RCA cables from stereo pairs into single channels. this let me do a left vs right channel 1200.6 while keeping my wiring neater.
made sure to get some heat shrink over the center pin. took a tip from a friend and used some forceps to stretch out the heatshrink a bit to slide over the jacket and out-folded shield and common.
took a couple evenings, i've got nothing but time these days. made some waste:
i took a break each night for an icecream sandwich:
and done. i usually use blue heatshrink to note the source/sink side but ran out. so i used yellow instead. my buddy pointed out they look like McD cables now. oh well.
i had a chance to clean up some other wiring from the front of the car, since it's not crossing over the other side.

Fantastic build and I enjoyed the interview at the finals. With that much power, did you have to upgrade the alternator or do anything other than a single run of 1/0ga? I know class D draws less than A/B but I didn't realize it was that much less.

Thanks. I went up 1 group size battery, picking up 10ah of capacity. Factory alternator is 130a or so. It’s all been great.

This whole build is awesome! Your trunk setup looks amazing and the covers are �� I aspire to make my scion xB look this clean!

not much else to do but tune, especially during the state of things.
when i was first trying the ps8pro, i was amazed at how well it sounded compared to the helix pro mk2. for as many times as i've hit reset, rethought tuning from the ground-up, changed amps, added/removed linedrivers, and so forth, high frequencies just sort of always sounded a bit inaccurate.
high frequency attack/decay is much better on the ps8pro than the pro mk2. i guess the mk3s and ultra are supposed to sound much better but the ps8pro was a much more affordable option. also, no more director.
coming back to this. any difference w/ the high frequency articulation have been fixed w/ the ps8pro and tuning.
