    HD 800 S Anniversary Edition

    There is a company in the US called Colorware that will do almost any colour you want on your HD800/800S including some very wild greens and pinks. This one is my favourite though.......

    HD 800 S Anniversary Edition

    I am not very excited about this and wouldn't swap my regular black HD800S for these. I wish that Sennheiser had launched the next generation 800 model for their anniversary instead of this purely cosmetic effort.

    Review by 'dadracer2' on item 'iFi audio ZEN CAN'

    In an effort to do the right thing I have made an attempt to recreate the ifi Audio Zen Can web page on my own desktop with my own Audio Technica ATH MSR7b headphones. You can see the proper image here https://ifi-audio.com/products/zen-can/ alongwith a whole lot of technical details regarding...

    Cayin HA-300 Flagship Tube Headphone Amplifier

    The sensitivity on Klipsch speakers seems to be calculated in a unique manner but in reality is about 3db overstated compared to most manufacturers. So if we say that's 99-3 , you should have a real world 96. The impedance curve is supposed to be reasonable so it comes to the size of your room...

    Thanks, I will check these out.

    Effect Audio - AKA Balance Adapter

    It looks very well made and will match the DAPs well for style but €200 will buy you a whole new DAP or pair or headphones. This feels like a number has been chosen to see how far it could be taken.......

    Cayin HA-300 Flagship Tube Headphone Amplifier

    I think it is to show you have 3 impedance settings on the amp to match a wide variety of headphones and in order that the headphones are not adversely affected in regard to their frequency response. Either that or they are an air force display team........

    Sennheiser HD800S Unveiled!

    If you really like the sound of your ZMFs already and it would be reasonable to imagine that's why you bought them? Why not go for a more top of the range ZMF? I mean what I think of the Ayra vs HD800 doesn't matter as it's your money, your choice. If you try your existing headphones with a...

    Sennheiser HD800S Unveiled!

    No problem and you do raise a good point about 300 ohms, but I guess a lot of the modern valve (and indeed SS) headphone amps are now coming with a range of impedance settings so you can better tailor the amp output. I guess that the HD800S is less stressful on an amp than if it were 300 ohm and...

    Sennheiser HD800S Unveiled!

    I think you misunderstood my meaning. I was responding to the chap who said they were 600 ohm. I realise 300 ohm is still quite a bit and need more to drive them than 32 ohm.

    The HD800S is only 300 ohm.

    Cayin N3Pro: DAP with Vacuum Tube

    Are we saying that it will not stream Tidal/Qobuz or indeed other streaming services? That would be an issue for me as I don't have a lot of music in files.

    Cayin N3Pro: DAP with Vacuum Tube

    I'm confused. You are saying this does not do streaming and yet it has WiFi connectivity. How or why would it have this if it were not capable of streaming?

    Cayin N3Pro: DAP with Vacuum Tube

    Thanks for posting this. So it uses an actual power pentode......oh my word! I cannot wait to see how this sounds in triode mode. It could be the very DAP I thought would never happen.

    Cayin HA-300 Flagship Tube Headphone Amplifier

    The choice is very wide but I wouldn't get hung up over the chip. It is all about implementation of the chip which gives the DAC its overall sound. There is of course the Cayin CS100 DAC which has valves in the output stage and should match well.

    Cayin HA-300 Flagship Tube Headphone Amplifier

    I'm not sure where I read it but I believe that Cayin tried a number of 22DE4 before going with the RCA. Maybe Andy knows or can comment? In the meantime yes it would be interesting to know if you do hear any difference with the Sylvanias. Are they NOS by the way?

    Cayin HA-300 Flagship Tube Headphone Amplifier

    No, just trying to help out the other chap in his request. I would not expect changing them to make any improvement on the sound quality though as they are power supply rectifiers aren't they? Now having said that I expect a flood of replies saying that's not the case!!!

    Cayin HA-300 Flagship Tube Headphone Amplifier

    I meant to ask this before now, but has anyone tried the Audio Note 4300E valves as a replacement for their 300b? They are made by PSVANE specially for Audio Note and feature molybdenum anodes. It look like they will cost around the same as PSVANE WE replicas or their Acme 300b.

    Cayin HA-300 Flagship Tube Headphone Amplifier

    I'm pretty sure you can, but I'm not sure why you would want to do that unless you are thinking of using electrostats and so are connecting an adapter box to the speaker posts. Otherwise if you are using dynamics or planars you will miss out on the balanced connection and variable impedance...

    Cayin HA-300 Flagship Tube Headphone Amplifier

    I found these speaker results by trial and error and not by the physics which on reflection would have made more sense. Oh yes and corner/rear wall reinforcement helps. I ended up with some pre loved Horning Perikles which are made for corner placement. The resulting sound levels are hard to...

    Cayin HA-300 Flagship Tube Headphone Amplifier

    Over the years I have had hum issues with a number of the valve amps I have owned and most of the time it has been a grounding issue or a proximity issue with other transformers such as SUT for phono stages. If you are getting some hum on XLR at max volume I really think this is not an issue...

    Cayin HA-300 Flagship Tube Headphone Amplifier

    It works very well but is dependent on speaker sensitivity, impedance and room size. I bought the HA300 with the plan to use it as an integrated amp with speakers and headphones and am very happy with it in that role. If your room is of average size then you need speakers which have an...

    Audio-Technica ATH-MSR7b Impressions & Discussion Thread

    Thanks for all the input and recommendations. I think you are correct and that the T5p will be a better answer. I am with you on dark and muddy sounding headphones. I had some Meze 99s very early on and before they made it officially into the UK and they are good but the treble always felt...

    Audio-Technica ATH-MSR7b Impressions & Discussion Thread

    It's really up to you. Why not get the headphones and then listen to few dac/amps and see what you prefer. Some folks will want to keep it neutral and others may want to inject some warmth but there isn't one answer for everyone. You get to choose!
