Finally got to listen to the 'correct' CDR Dave sent.

My impressions are a bit late, can't do an A/B/C and this is all from memory and based on my notes, but the CDR sounds even more focused than the #, with better instrument separation, making it easier to hear what's buried in the mix. But I think the most obvious difference for me is the bass. Everything sounds clearer.

Maybe I am not recalling the sound correctly, but the CDR's bass seems more impactful and the sound more dynamic?

Just an fyi, I am the friend and customer that Dave mentioned previously that prefers spinning CDs vs streaming or listening to ripped files. I had purchased a dedicated music server with Roon, Tidal, and ripped all of my CDs to the hard drive. I used Tidal to find new music and it covered most of my vinyl collection. I have since gone back to spinning CDs and vinyl and Iím a happier camper. Iím using Jayís Audio CD-2 MKII transport and the Jays Audio DAC Signature. Iím looking forward to getting Daveís HDMI cable to take advantage of the I2S interface.

  Don I have been preaching that for some time. CDs using a dedicated transport just sounds better. Depending on ones server it can be really close however still no Cigar. I prefer Qobuz to Tidal in sound quality. Dislike Roons sound. Using iPeng remote instead. Is not your I2S connection Ethernet ?
  Aqua just came out with a dedicated server that Aqua feels equals their dedicated transport.  High res recorded in high rez is the only reason IMHo other than general listening a streamer is needed. There is not much music recorded in Hi-Rez other than SACD.
   Do not like at all upsampled anything. If recorded in DSD then OK. Still spinning those shinny discs.

 re: the accutons; well, while not having heard mr blume's top creations, all i can say is i've never heard anyone who has, say anything less than they're one of the best speakers they've ever heard.

interesting you should mention the heil amt's.  their largest driver - 6" tall -  is rated 800hz to 20khz and 96db efficient.  i've always wondered how a stack (8, 9 or 12 drivers per side) would sound.  retail for 24 of them would be $4800 - not chump change, but within the realm of affordability.  ( and if you wanted to buy 24, i suspect the mfr might provide a bit of a price break.)  i wonder how low you could cross them, if running that many.  12 drivers would be something like ~106-107db efficient; i bet you could cross them over quite a bit lower and be successful, w/eq...

best,

doug s.

Hi Doug,

Yes, he picked some of the better drivers which is good. There are still some questions I would ask myself though.

The tweeter looks pretty good, although I would like to check out the off axis response. Does it beam? I take it he minimized that
effect. If I had a choice, and gobs of money etc I would go for the Heils air motion transformers, maybe even the ionized helium, requiring tanks. Nah, the tanks are too much bother.
But so far so good.

The midrange is another matter between 2-4khz, within the most sensitive portion of the ear. I still don't like the 5khz and above
either as there is not a gentle, linear downward slope from 1.8khz to 8khz. That 5db "roughness in response" is going to show an unevenness when combined with the tweeters overlaping response. The worst part is the dip covers a whole octave, well above
the 1/3 octave width Rane claims is the minimum width necessary for being perceivable. Less than 1/3 octave is generally not perceivable.

Forgot to mention DB spikes and dips are directly added. For instance, if we have a spike of 5db, then the overlap will show the
5db spike. If we have a dip of 5db, then the overlap will dip 5db.

Not to worry Doug, I have had the same problem whenever I look at any 3 way design. Overlapping always occurs, worse with lower order crossover designs. That is why I went with a two way design, just one overlap to deal with, and at a much lower frequency.

Cheers

Well, I made two more adjustments to the system. I went back to ten 18 gauge wires on both legs of my speaker cables.
This necessitated the lessening of the inductance by ~1 inch of one turn. These adjustments affect mainly the
upper bass/lower midrange output, which affects the perception across the entire audio band.

Going to check over many selections to see if any other touch ups might be necessary.

This is one minute adjustment, yet still made a positive sonic difference in the "lab".

cheers

Here is an orchestra piece that will test your entire system, from bass thru treble.

Thanks so much Dave! I have received tracking info. Still very humid here in PA. Iíll look into demag.

I think Iíll start a new thread on my experience so far with the Jays Audio stuff and my impressions of coax vs bnc vs hdmi.
Sounds like a plan.  Since I donít have any audio devices that use HDMI you are a beta dude!

That Jays Audio gear looks great!

Well, you have been a victrim of my success.

I recently finished a rebuild of my cryo oven, part of which was a new seal system I came up with.  The method I use is a lossey one where the LN2 dissipates through a controlled leak.  I use a needle valve to adjust the boil off.  I put your cable in at the beginning of the week (Tuesday morning).  Before the upgrade it would take about 72 hours for the nitrogen to boil off.  It is finally ready today.  I'll be sending you a tracking number in a few minutes.  I'll be very interested to see what you hear.   :)

CD's are still the deal for me.  I use Tidal because I didn't care for Qobuz SQ and being clunky to use with a Mac.

Try to find one of the old RatSnack bulk tape demagnetizers.  It really does make a difference for the better.  Also, try using a static trearment on the label side of the CD and see what you think.  Out here in the dry SW static is a big issue...  Zzzzzorch!

NY Audio Rave / 45 vinyl giveaway!?
« Last post by goldlizsts on September 12, 2020, 09:49:40 AM »
This group, as well as many others, are pretty much on life support.  I check back here once in a while, but haven't seen much posting.  Anyhow, I want to give away? my 45 RPM records.  Is there anyone out there playing with them?  They're all hit songs from the 50s through may be late 70's, even early 80's.  I kind of stopped when the disco craze came in (Donna Summer).  I'd say I have at least 100 of 'em, and likely more, in a box.  Anyone?

Hi Don,
Yes, I agree with your assessment, especially if you were using Roon... Roon degrades the sound quality, even though the "experts" say it can't... Confirmed in-person over a year ago with some fellow audiophools... "If you got ears, you gotta listen!"

My $0.02,
Pete
