    HiFiMan Susvara

    In regards to wanting something to drive well ... the upgrade it worth it, but it scales logarithmically. Spend £1k and it nice. Spend £12k and its godly. Spend £100K and its otherworldly! I have yet to hear the £100k. If you only have budget for £1-£2k then its easy to miss where Susvara...

    HiFiMan Susvara

    Why would you ruin a Susvara making it "closed"? Putting your hands "near" the earpads is enough to utterly wreck the openess. I appreciate people need closed backs for particular reasons, and that will be a compromise! It absolutely should not carry any of the SUSVARA letters in its name...

    How very odd. The fuse that was in the unit was the original. My assumption was that change of 22DE4 was the issue. There was NO issue?! The fuse simply blew. SO i went back to original rectifiers and all wasfine (after changing fuse). I then rolled the new rectifiers in pairs until all 4...

    Help please! I turned my Cayin 300b mk2 on a few moments ago and was distracted. When i turned back, all the lights were out! I had changed the rectifiers for a new set so am assuming a bad 22de4. I have tried a new kettle lead, no power. I have checked the two fuses next to the 300b's both...

    No shipper will insure valves!! For one, they are glass, for two they are ultra sensitive! There is no insurance. For everything i have ever sold, if someone had an issue and was immediately unimpressed, i woudl fall over myself to offer a refund. I did it recently with a set of tubes... yes...

    Point him to the forum and he will understand your full intent! If he pays bank transfer then who cares about pick up! As you say cash in hand hes free to do as he wishes! But paypal invoice is not bank transfer. If he pays it its like being a business for goods type transaction. I.e. it...

    Oh i had not read that!! Very interesting then maybe worth giving it a go. I can find metal tubes in the UK most are over seas. And yes Susvara hides noises that other headphones lay bear! I sold some tubes to a Focal user and he claimed then noisy. I got them back to hear absolutely...

    Im saving my pennies!! My big problem is like i like to have at least 5 tubes as a set. Then i like to have 2/3 sets like that to maintain the long haul. So, 15 tubes x £100 = £1500!!! And then one day i cant have that anymore!!! Thats MY probem! During my search for quad matched sets, it...

    Visual astronomy is useless in light polluted areas except for planets, moon and sun. From dark skies, visual astronomy is spectacular. Ive always been an imager and rarely find time to remove the cameras!!! Its an amazing hobby and i love beating the odds as best i can!

    As a buyer ... YES!!! Because you can overturn the payment. As a seller its a foolish thing to do ... As a seller you want to be in control of the money. If those goods belong to ME, then I will be in control. I buy and sell a lot of astro gear. There are times people simply wont buy. But...

    Most of the metal cans i see are far later productions and i have no interest. I played in 6sn7 quite a bit and was happy with TungSol Black Glass Oval Plates ... then my next step was GEC CV6 and Mullard CV6. For me personally, and with my gear, nothing has floored the Mullard White prints...

    No, light pollution is my issue. I live in Bortle 7 skies and its evil! SO i can do Narrowband fairly well, but LRGB is hard work. I still try but i need to put 20 hours into an image not the 1-2 hours at bortle 2!!! I wish i could afford to move my gear to somewhere remote! I shoot in mono...

    I would NOT allow Paypal Invoice. This potentially allow him to turn over the payment. It NEEDS to be Friends and Family or bank transfer ONLY. REFUSE ANYTHING ELSE. THe problem for you is that he will argue if one of those valves go bad in transit, he will overturn your payment. Most of us...

    There are many more bright tubes out there than Mullard CV6. White prints are still my favourite, their sound is massive. On an equal pegging, i also love the Russian 6S5S/6C5C mesh which are a 6C5G true equivalent (cryllic makes this awkward!). Over the Mullard whiteprints, they just offer a...

    I dont know where i got that from .. i remember seeing a flow diagram for what i thought was this amp and i thought speaker outs were bot part of the preamp circuit... must be an age thing .. sorry. I cant even find the diagram now!

    Have i understood correctly, in order to use off the back of speaker outs, you need a seperate and additional Pre amp? Otherwise its full ouput i believe? I thought i read something about no preamp in speaker out circuit. So no running headphones off the back without additional boxes.

    Youve had the Abyss headphones for 1 year on this amp? With my susvaras has has never become any "worse" over time. I tube swap all the time and it blows my mind. Maybe if you have only recently observed it then its worth a checkup. Please post back in the group if you do.
