Reprise NOS Old Dale RN65D vs NEW Dale RN65D

[norburybrook]

Yes, flipping back ad forth is the best way to detect a difference IMO. You can sort of do that by switching between the two files and clicking on the same section (time reference) to hear the same phrase from each sample back-to-back.

yes it's easy to do in a modern DAW just put the two files on separate tracks lined up sample accurate and level matched and snip and mute sections on each track then render the master mix out.

My personal thoughts after putting the old ones in; Less spikey, smoother and they have an open, airy feel while playing. The last thing was the most surprising to me.

While you are not revealing which is which, here you are contaminating the results by planting the suggestion that there is a difference between the samples, and even describing what it is that participants should be listening for.

Martin I had the same thought this morning when re visiting this thread

I thought that a good way would be to make?edit together one continuous file but flip it at various points between A and B and then ask people to tell where the sound changed if they could and flip back and forwards between the before and after versions through out.

I think even with Erwins 'suggested' differences that would be easier to hear differences or not.

Ok 1 teaser: 1.56-1.58
I have the 44.1-16bit files if you want to do a daw compare.

Erwin,

why not do as I suggest and then just ask people to say how many times it switches between one and another in the 3 minute clip?

I'm on the road but I could drop them into my DAW on my Surface and do that sure how big are the files?

also it would be interesting because YOU wouldn't know either if I did it

I'll PM you

There is certainly a difference: one was using the old Dales and one was using the new Dales.

I guess we'll have to take your word on that! But seriously, I believe you, and thanks for taking another run at this. Other issues are the sample size (including the number of participants), and pre-conceived notions about the possibility that similar resistors could contribute anything audible to the sound quality.

I listened through my studio head phones ATH-M50X and Focusrite 6i6 as the audio interface. I hear more treble and presence on sample 1 than sample 2. I prefer the 1 (on the cleans) because it feels more airy to me, and I like treble.

Thanks for your work on this!

Are the NOS Dale RN65Ds indeed metal film? I read a post on this forum speculating that some may have been carbon film.

Best wishes,

Andrew

RN65D are mil spec metal film resistors. I cant remember ever seen a post on this forum speculate it is carbon film. Do you know which thread?

[erwin_ve]

Thanks a lot Erwin for your efforts!
I also A/B-ed various sections of the two files using a pair of reasonably good AKG headphones and to be honest I can't hear a difference....but maybe my ears are not that great anymore.
It would be great if you could upload the wav files externally.
I would love to give the uncompressed files a try.
Thanks again!
I agree, great playing !!
Best regards,
Markus

Thanks for listening Markus! I will post a link ASAP with the wave files. They are 40Mb each.

Thanks for posting! I have to check , I believe the RN65D I used are made after 1970. The spec sheets Structo posted are no longer up and running, cant check.

Here is what I see. Sample 1 and Sample 2 will not play. I can download the MP3 files and listen, but as you can see they are not named Sample 1 and Sample 2. Which is which?

[erwin_ve]

Martin: the Infamous HTML5 compatibility of Safari?
Sample 1 is the DaleRN65Da file
Sample 2 is the DaleRN65D1 file.

Erwin

[martin manning]

Probably. Thanks for the clarification!

Sample 2 is the DaleRN65D1 file.

Yeah I use apple for work, and used apple at home in the past, I almost never used safari because it was so crap Use chrome or firefox

I couldn't tell a difference, before and after the "teaser" reveal. Sony MDR-7506 headphones, onboard Realtek audio. I'm in the magic parts skepticism camp.
