Hi, Just a question that might look strange to a few but.... We have all lessoned to various persons having tested/reviewed/change the fuse , and report sonic differences (same for the cables). I wonder if a few of you have tried to use "better" fuse holders, or have tried to remove it (and...

It is exactly my conclusion !... Thank you very much

Hi, I almost never ask a question like "what is the best" because I know how system-dependant the answer is... But after having search the web during hours , I did not get a clear viewpoint regarding these 2 well known LPS.... The Power supply will be used to power 2 devices: -an UpTone...

Sorry if it is a wrong forum (maybe a moderator could move it in the appropriate one...).   I know that a 12V linear P.S. would be OK (I have already built a few of them), but i am looking for a recommendation based on your experience....

Hi,   The Chord 2Qute DAC is bundled with a very basic power supply: a simple 12V Wall AC adapter that looks a bit crappy...   What would be your recommandation regarding "the best external power supply" (that could be an accumulator...).   Thank you very much for your replies,

I do not have the Service Manual, and as Lite removed the reference of many parts, I assume that they do not want the skematics to be published...   Maybe you can ask the websites dedicated to the Service Manuals : if it exists, it will not be costly.   I am still interested by it if you...

  Quote:   Agreed: this is a point we have to follow-up ! maybe the final release will correct this pb, if not, I will search for another headphone, even if it is almost impossible to find "the perfect one"...

The review said that the HD-700 tends to have a risk of sibilance.... this is a problem for me, that could keep me far from the HD-700...   Currently I have a HD-600, I will try to get more info on the Audeze ...

I am in the process of choosing between the Lite 83 and the AudioGD Ref 7, but unfortunately I have no way to compare them.   ---> Is there a more precise opinion on which one is the best, assuming that we all know that they are 2 excellent DACs ??   ---> I am looking for a photography...

I did find the dedicated topic related to the OPA627 / OPA637 installation in the RKV. The people who tried this upgrade confirm that it is necessary to add a 68pF capacitor on the OPA637 to ensure stability, but the sonic improvement seems outstanding ...     Quote:   I planned to...

  Quote: I am going to perform this upgrade on my RKV-II as well, and found the OPA627BP on eBay for 15$, but...following your remark I prefer to buy from a reliable source like FARNELL for example: 30€ each, but I am sure of what I get....   I will do the upgrade with the OPA637BP ...

Thank you VERY much purk !   I start reading !....

  Quote:   This is exactly what I am looking for days, but I have not found this post ! unless I made a mistake with the search... please give me the URL if you know it .. Many thanks  

  Quote:   Yes, I confirm that the RKV-II is still in production, but the price considerably raised: I believe it is around €2.200, but negociation might be possible based on what I have eared around...   The impedanzer is also in production and i am waiting for the price: I will...

  Quote:   I have been told that the original LF351N op amp can be changed for much better op amp: do you know what kind of op amp can be installed instead of the LF351N ??? I know that the OPA627 are very good but nobody can confirm me that they be installed in the RKV-II instead of...

As a few of you have done in the past, I plan to try to upgrade the LF351N op amps of my Audiovalve RKV-II by better op amps, such as the suggested OPA627.   I would like to know if I can simply replace the LF351N by the OPA627, or if there is some particulars points to check , based on your...

  You are right ! I bought mine around 850€ some years ago...     That's for sure... We should start a back-engineering process to define the skematics of the amplifier, and it would be far less costly to build it as a DIY headphone amp... There is not enough parts to make this back...

I have just found mine that was sleeping in its parcel since 3 or 4 years, because I have almost never used it (I moved to another town just after purchase...).   I am about to turn it on for the first time since many years ! I will tell you how it sounds with my HD-600.   By the way...
