HdB Posted May 3, 2018 Share Posted May 3, 2018 The sound is transformed with a decent linear power supply and a Russian 6H23 tube and running it in for well over 100 hours - given enough operating time, this is an incredible 'bang-for-buck' item Good quality linear supplies like the Geissler, the China S11, etc cost about the A$300 but you can diy for less than half this, if you can find/make a reasonable case Although the supplies EH 6922 are quite good, the Russian 6H23s (1975 silver, for example) are slightly more transparent/dynamic/etc and cost about A$60 +. There is a short protection ring (CH-FM-39, silver finish) available from 'vt4c' in HK (also known as HiFi DIY) for about A$12 + frt, and can be easily attached to the top cover plate if you don't like the exposed top of the tube 1 Link to comment Share on other sites More sharing options...

So $300 for a better PSU, and another $60 for a better tube? Link to comment Share on other sites More sharing options...
HdB Posted May 4, 2018 Share Posted May 4, 2018 As you're up North, you could possibly 'talk a deal' with the guys from Geissler about the price as it's a pretty simple supply of 28 volts and around 1A - the amp draws just on 370mA once it's warmed up (0.36A) but it's been often said that a higher rated supply just sounds better, so ask Clay about this too. There's a whole range of these readily available - Teddy Pardo would possibly build you a custom 28 volt one with the proper lead for about A$450 (see TeddyPardo website) - the S11 one I mentioned from China is based around the AMB Laboratories 'Sigma 11' design and is very well regarded and good value - you can also get some good quality laboratory linear supply with a capacitor on the output for maybe $150 too - you'll need to get a 2.1mm plug on the supply lead (for the headamp), not a 2.5mm one (easily mistaken). The 'better tube' is a bit of a misnomer as it's just a bit different sound to the supplied Electro Harmonix one - If you're looking for 'more detail' with, for example, a really smooth dac and headphones, it might be quite useful - it's something to, perhaps, look at later on, not something you need straight away Link to comment Share on other sites More sharing options...
Volunteer sir sanders zingmore Posted May 4, 2018 Volunteer Share Posted May 4, 2018 @HdB I know you're trying to help, but the poor OP is just trying to sell his amp. I'm finding your posts to be very technical and distracting and possibly not really relevant to the advert (my opinion only, the OP may be perfectly happy, in which case I apologise and I'll go away ) Link to comment Share on other sites More sharing options...

Doctor Faustus Posted May 4, 2018 Share Posted May 4, 2018 I will add.... even without an expensive linear psu this amp sounds REALLY good. 1 Link to comment Share on other sites More sharing options...
Tylerhk Posted May 4, 2018 Author Share Posted May 4, 2018 I think @HdB is helping me to verify that the amp has a lot of potential to unleash. @Sir Sanders Zingmore Thanks for your concern and you are right that I care about more whether I can sell actually. @ToyoBoyo I know it is a great amp but as hd800 is my only main headphone I somehow need to look elsewhere 1 Link to comment Share on other sites More sharing options...
Doctor Faustus Posted May 4, 2018 Share Posted May 4, 2018 Well I just brought my HD800S to my study and plugged them in to check the sound. The sound coming from this Cavalli CTH is VERY good. Maybe the HD800 may not be as mellow as the S model but maybe you should open the box and have a listen. Reviewers are often wrong... or they have their own bias.For sure, whoever buys this will get pleasure from it! Link to comment Share on other sites More sharing options...
Tylerhk Posted May 4, 2018 Author Share Posted May 4, 2018 @Toyboyo well I am tempted to keep it or at least try it then. Thanks! Link to comment Share on other sites More sharing options...
