post #2806 of 3704
I have said this before but will repeat regarding the DAP's I think that the present crop including Vinnie's mod of the AK's represent the biggest improvements in sonics over the non high resolution players, they represent the biggest leap from what we had before. I think any improvements from here on in are going to be much smaller as the technology is all pretty much the same, just slightly different sonic flavours.

I think Vinnie's mod is the natural extension of what is ultimately possible with the DAC's available, the no compromise, no holds barred solution. It is specialist and I feel will take a long long time to beat in terms of sonics as Vinnie has taken presently what is available to manufactures to its ultimate level.

Now, if and when new hard wear in terms of components come out then that will alter but from what I can see around there is nothing new in the parts catalogue that says that so the new players coming out now can only change the sonic signature, not I feel improve it unless of course subjectively.

Then there is the aspect of Bugs and usability. Its why I went the AK route in the main. I have had next to no issues with mine compared to my 801. I loved the sound of the 801 and am sure I would love its successors sound but to me they are half products, continually needing firmware updates as well as other issues.

It was lauded that the 901 was better value over the AK120 but when it became clear that to achieve the same levels of sonic greatness it needed the balanced amp card the price became the same.

And though it does not matter in terms of sonics having now had a 901 in my hands it feels like a plastic toy from the 1970's in terms of build feel.

Add to that the reviews outside headfi from the serious HiFi press who I have grown up with and value their opinion who say the AK120 is a remarkable machine and worthy of many awards as the best in it's field ( the 901 not even showing!) then I am happy with what I have. I may end up after a year doing the RWA mod if I feel like getting a small amp for ultra portable use but until then this unit gives me immense sonic pleasure, ease of use and plenty of memory combined with exceptional build quality.

Anyway, off Topic i know. Bmichels, what factory code is on your DF96's? did you get them from the Canadian or US supplier?

With more use the similarities between these and the Stuttgart made Lorenz's show they are inseparable in terms of sonics.

Gavin. I am very much looking forward to the day you do some tube rolling. I know your so happy with the stock sound so it will be interesting to see what you feel like about the influence of other tubes.

I got them from the US supplier.

 

Factory code ?  under "PHILIPS DF96" I can read " TE1 D613 "  !  Is is this the factory code ?  What this code means exactly ?

i think underneath that you should see three alpha-numeric numbers in a grey colour but knowing you got it from the US seller is enough as all his are Hamburg Valvo made Philips with the plant factory code "D"

the modder 's diary part 06:

 

a lot of parts arrived today, some electronic parts, but first of all all the switches, potentiometers, 3.5mm connectors, nuts and parts to mount the switches and potentiometers:

 

 

i found this nice output transformers for just Euro 4,70, not SE output transformers, but 4,8,16 ohm secondary impedance and should have somethink like 2,4,6,8,10 KOhm pprimary impedance, so nicely fitting the needed specs. the silver thing with the black knob in the middle is a NK SWITCHES 2x 6 positions mini switch with silver contacts and can be used as impedance switch within its specifications (125 volt, 50mA).

 

also my new digital multimeter arrived as the old and very cheap one was not correctly working, especially when measuring resistors:

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality


also i got some cables needed for the power lines and the connections for the signal part from tube output / impedance switch / output transformers to headphone out.

A Question may be for IAN, our " Philips DL92 Expert " :D

 

I have quite some Philips DL92, but... of 4 different types !  :eek:

 

--> Can you explain to me those variations, and tell me which one are those you like most.

 

Note the funny one with the stamp. It written  " 217" and "21° S.C."  at the bottom !  

--> what does this mean ?  I have only one of those, so with which one should I pair it  ? 

 

 

 

 

 

Also, of the type on the left (with "MADE IN HOLLAND" written on top, in curved line), I have half of them with a dot of green paint on the top and with OD writen on the back !?  

 

--> What does OD mean ? Why the painted dot ?.  

 

 

 

Thanks in advance for your advices

You know, those have me baffled. The extra printing you mention is not factory or date code information as far as I am aware. Its interesting as well that the O.D one has that flash of white paint. From what I can find out the green dot means they were tested So I am guessing the green dot ones have gone through stricter quality control, perhaps for medical usage? I would try the green dot pair together and see what the sound is like. I think it should mean the tubes will be really quiet in operation, more stable.

thanks, I will try first the one with the painting, paired with the Philips DF96 .  I will let you know.

 

But... do you have an idea of what  O.D. stand for ??

 

 

By the way, something very funny is happening:  

 

After all those months of tube buying-roling-testing, I recently re-installed the original stock tubes combo (RCA 1U4 / Raytheron 3S4) and... I found it VERY Good ! may be my It could even end up becoming my preferred choice ?? Is this hapend, then... i will have follow a loong road...all in circle :-)  but, don't worry, I really ENJOYED this journey !

I think the thing is you had really great tubes come as stock. shikada San got some really lovely high quality tubes in after I got my amp. The stock Sylvania's we're not bad sounding tubes, just very noisy which took away from the amps natural inky black sonic background. Having now purchased the tubes he fits now if I had had those as stock I probably would have not done as much tube rolling in truth as they are indeed lovely tubes and the more they burn in the better they get!

I agree, Shikada San must have provided me a very good set !

 

But, you did not told me what you believe  the  O.D.  printed on my tubes stand for ?

bmichels,

I've discerned from your postings on various threads that you seek audio nirvana, as do your fellow compatriots here in our joint pursuit of musical realism and sonic clarity. However, everything that isn't a live experienced performance is compromised in some way or another, so please don't become overly fixated by the marginal improvements that one valve may have over another. As you've rightly pointed out it's all about the music, so let's enjoy what we have and play them tunes!

Cheers,
Andy.

Shikada-san just confirmed that both the TU05 and 06 will make an appearance at the Mook Headphone festival in Singapore 13-15th Dec. 

 

Am really looking forward to this opportunity.
