Hi there, I am reading the thread and trying to understand it nevertheless I am not a specialist - just music lover or something. Still I am very interested in the topic because at the moment I feed my DAC from a media player via SPDIF /BNC/ considering this type as the best jitterless...

Quote: We are expecting your judgment after some burning time, What capacitance you installed - 0.47 ? Rgds

The caps value depends very much on the rig - in my case Chris Venhaus recommended 3,3 uF for deeper bass and was right - you can try with some cheaper brand for a test.  

Quote: I am sorry I am not following the tread but do you mean replacing the output 2,2 caps with CuTF 0,47 ?

Hi there, I think Robert made a wrong try buying them CD players. My opinion is that ONLY DENON selection is good - the signs of the chips are green colored / K and J grade/. IMHO Regards, Ignat  

Thanks a lot ! I hope he will become  a head-fier ! Cheers,  

Quote: I am sorry guys I am so busy with some other stuff and simply had forgotten this project /in the meantime I have already a grandson - DAVID/ so no sense to make any suggestions before I go back there - probably end of the summer. I live now at the seaside where I miss my audio rig...

Quote: I fully agree with this. I have tried plenty of resistors in that range and for me the best choice /compromise/  is 181 ohms.Please note again it's quality is very important - should be extremely low noise one. Cheers Cheers

Quote: I am glad you enjoy the upgrade ! Be good, Cheers

Quote: But please do not forget you have to place a VERY good quality resistor for the I/V conversion there /in my case Z-foil bulk metal ultra low noise Texas/ Cheers

Quote: The grade is marked after the chips are controlled /after production/. Obviously the grade will be marked by hand by a tampon - just think and do not worry . Cheers,

  Quote:   As a matter of fact that was suggested earlier by someone in this thread - I went further and after the good result with 100 uF Elna Silmic I have installed one Elna 47 uF in parallel /from the bottom of the first one/ - so altogether 147 uF and in my case the picture got...

Quote: That's right - I've cut all the connections to the USB and Optical input - completely out. Cheers

Quote: That's right and I do not believe they are fake Cheers,  

Quote: That's right and depends on the input impedance of next component in the system - preamp or whaever. In my case for example Chris VenHouse suggested 3,3 uF in order to get better /cleaner and deeper/ bass. Cheers,    

Quote: You are absolutely right to decide by yourself - just check here and there before final step. Michael Percy is a high end guru - http://www.percyaudio.com/Catalog.pdf  and he says - Soft Recovery (FRED) & Schottky Diodes "Fast Recovery Epitaxial Diode.The FRED soft recovery and...

The most important  parameter is of these diodes - "The RHRP8120 is a hyperfast diode with soft recovery characteristics (< 55ns). It has half the recovery time of ultrafast diodes and is of silicon nitride passivated ion-implanted epitaxial planar construction" - that is the issue ! Cheers,

Quote: I am using these allover my components - not the fastest /55ns/ but acceptable - FAIRCHILD SEMICONDUCTOR - RHRP8120 - DIODE,FAST,8A,1200V,2-TO220AC Cheers.  

Quote: I think I will come with some ideas end of next week, these are bypassing the electrolytic caps at each power supply point of the receiver and dacs - not so easy to decide their type and value - my opinion, Cheers

Quote: They have too "engineering" sound -  the Korean L seem more musical   Quote: As far as I understood that project works for a penthode - we have a double triode tube ?   Quote: That is an example of the completely different approach and mentality ...

Quote:   Quote: Thanks ZenFire , I have registered to the Decware forums and will have a look at the topic tomorrow. The gain is you just avoid using the ****ty internal OpAmp and go for a passive I / V conversion which is let's say High End approach / what I know/ Attached...

Something like that - just principle schematics -   the old one   the new one      Please neglect the other parts and connections - I will send you the real schematics later - not completed yet, /All above info is absolutely not a military project as the Havana schematics -...

Quote: Easy, just have a good look at Robert,s posts concerning the PCM56 opamp and you will find out where to start /pin 13/. Will post a brief schematic where to go further. Cheers  

Guys, please stop counting the colours - it is no good for you eyes - it is easier to have a look here - ID Value Spec /Grade Parts R1 301R 0.6W, 1% RESISTER R2 100R 0.6W, 1% RESISTER R3 1K04 0.6W, 1% RESISTER R4...

Quote: Sorry but I have several products at home of LINN, KENWOOD, HARMAN KARDON and I think these are not comparable with Lilliputs but all of them are providing very profound schematics and manuals. From another side you read on the MHDT website - http://dhost.info/mhdtlab/havana.htm -...
