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

That all sounds complicated.

 

So $300 for a better PSU, and another $60 for a better tube?

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

@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 :) )

Anyone's thoughts on matching with amp with MrSpeakers Aeon Closed? (6.5mm atm)

I will add.... even without an expensive linear psu this amp sounds REALLY good.

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

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!

@Toyboyo well I am tempted to keep it or at least try it then. Thanks!

      Item: NORDOST QX4 POWER PURIFIER
      Location: Melbourne
      Price: $1500
      Item Condition: Used but in good condition, please check out the pics
      Reason for selling: Surplus
      Payment Method: Pickup - Cash, Direct Deposit or Paypal + fees Only
      Extra Info: 
       
      Info below taken from their online website:
       
      QX2 and QX4 units are power purifiers that are affective without compromising the peak current capabilities of your power supply or the integrity of your grounding. Each QX unit contains QRT field generators (two in the QX2, four in the twice as powerful QX4) that alleviate the impact of poor quality AC power on your sensitive electronics, limiting RFI and timing errors. Place your QX unit(s) at the heart of your system and you’ll hear a lower noise floor, greater dynamic range, more fluid musical expression and greater space and ambience. QX units allow you to hear more of your music (and less of your system). Used in conjunction with each other as well as the QBASE-Mark IIs, Qv2s and Qk1s, both the QX2 and Qx4 provide a highly effective answer to the insidious influence of poor AC supplies on musical reproduction. And because of QRT’s modular approach to AC treatment, you can add additional units as you go along – they never become redundant. Once you’ve heard the sense of life and effortless musical flow that comes from having QRT technology in your system, you will want more – which is what makes the modular nature of the QRT products so appealing.
