I have the same adapter from Ian. This is the best adapter I’ve ever heard. Congrat bro! A huge upgrade compared to any other adapters. Which means that I have to built a better one Competition is always good to the market
Hi MarkView attachment 114439
I received Ian’s ‘short’ adapter today and promptly set it to work in my Baltic dac. Am posting this in the Horizon thread for the sake of continuity of coverage, though the information is equally relevant to all Lampi dac owners.
Using an early Viennese made Tungsram pv4200, I was most impressed by the immediate improvement in sound quality despite the adapter being new.
I was greeted by a grainless and clearer presentation, with a better evolved tonal structure. Arguably, this gain in performance was greater than I have often experienced between different leading rectifier options.
There is inevitably an interaction between the rectifier and the tubes following it, which in this case were valvo e83f (as a substitute for 6sn7) and followed by the extremely rare Tungsram e80cc nickel plates. In other words ymmv, though the pv4200 shares the same electrical spec as rgn2004.
My advice to people mulling over their upgrade options would be to allocate some budget into a better adaptor before considering more exotic / expensive rectifiers. You will get an immediate uptick as well as providing a better infrastructure for future tube upgrades.
What I find especially commendable is the effort and fast learning Ian has displayed in this endeavour. I had the pleasure of meeting Ian at my home at Easter, whilst his family were on vacation in London, and he heard his first 4v rectifier (Milan rgn2004). In the space of barely 4 months, he has widely researched the landscape and developed his own solutions with 3D printing whilst also having a demanding day job and a young family. That said, I’ve a feeling that Ian is only just getting started!
The elephant in the room is that the looks aren’t for everyone, and I for one will likely be hiding it away when not in use. Unfortunately the form factor is driven by the massive size of the Path resistor. As a long time sceptic of superfluous parts in the signal path, I can’t help but wonder how much better a native 4v psu / B4 socket would be in the dac, however I also realise that this path would only be for the purist minority.
Yes i have compared the siemens c3g against e83f with both using the xulingmrs / ebay adapters. E83f is more articulate and neutral than c3g though I have yet to try either c3gs or any more exotic e83f options. The valvo were cheapos to get me up and running. In my Baltic, it is possible to run a rca / single ended signal with just one tube per adaptor and I found this to sound marginally more pure than using a pair of tubes on each side.Hi Mark,
Did you get a chance to compare the e83f to the Cg3 tubes?
what adapters do you use for the e83f tubes?
