    Indeed, V5i are 39, versus the V5 at about 65. Lots of reviews on Head-fi;

    I see Profusion Plc are another U.K. seller.

    Hey guys,

    I know it's been a while but, we are willing to send more V5 and V5i (newer model) to anyone who post here. Just let us know what audio equipment you want to mod and how many units.

    Cheers

    PM sent! Another Najda DSP owner gave the below comment, which is the benefit I am hoping to get from these V5 units.

    "I've just ordered 3 paris of dual Burson Op-amps for my Najda DSP. These are a plug and play upgrade and are reported to be a great upgrade. Bigger bang for buck than linear PSU and much bigger than DAC changing.
    Will cover analogue input and output stages"

    Results are always application specific, and can never be deemed universal.
    In my case, using the KMTech analogue crossover boards and after much experimenting, I found the best combination was to use a Sparko's discrete for the input buffer and Burson V5 discrete in the crossover filters. This gave the most natural sound reproduction in my opinion and was slightly better than using the Burson V5 throughout, regarding timber with piano and texture in vocals for instance. This of course was with my choice of amplification and drivers. YMMV.

    I am very pleased with this combination.

    Received three Burson duals last week as part of the test offer, and after positive initial impressions I have given them some hours of play every day since and I am more excited about what they do for my system, which is as follows:
    Najda DSP preamp
    Nao Note II speakers with dual Alpha15a drivers for the bottom end.
    Anaview ALC0180 and AMS0100 on each side
    Mini Pc running Linux based WTFPlayer into Amanero USB port on Najda preamp

    I have the Bursons on one and a half speakers at the moment, since I was sent three initially with the rest to follow, which is not enough for this four way active system. However, the impact on my particular system is huge. LM833N are the stock opamps in the Najda which are supposed to work very well, though my system seems to need more, as I will detail below.

    Test track - Straight Through Boogaloo from Lyn s Une
    The first test I went for was turning amps on cold, playing a track which at -10db is loud and I have to turn down towards the end because the congestion of drums and other instruments going full whack becomes annoying, more noise like. Switch in the three Bursons and play again - immediately I am thinking the volume has gone up, yet the setting is still -10db. Secondly, the drums are sounding more real. But the biggest moment for me is I do not have to turn the volume down as usual at the end, since rather than annoying me at the end, I am now enjoying the crescendo at the end of the track

    So initially, it is like the volume level is gone up, which I am thinking is dynamics. Big moments in the music have become enjoyable, rather than collapsing. Further listening yesterday says I am hearing much greater realism in my music, where before I was not really convinced and hence my system was getting a lot of movie time rather than music time. That should change now.

    Anaviews lack an input buffer, and my Najda are run SE output at 3V, so I am wondering if the Bursons are adding much needed strength to the signal. This is a guess based on my reading about the Anaviews.

    I will add more later as it arises. Thank you to Burson for the opportunity to try these!
