Thank you so much - this is incredibly insightful. I'm in the UK - so have a limited selection. However, based on your info, I've found these: Power Tubes General Electric 6AS7GA Telefunken 6080W THOMPSON 6080WA 6080WB RAYTHEON JAN 6080 CV2984 Mullard RCA 6080 GE NATIONAL BLACK BASE...

Thanks so much for the recommendations. Any recommendations for replacing the 6N13S power tubes?

@LobalWarming & @JKDJedi thanks for your help - really useful and interesting info! I can't seem to find any Gold Lion tubes that match your recommended models for the driver or power tubes. Are there any specific brands/models that would be a safe bet as a great upgrade to the stock tubes?

Hi all, I have a Miltra OTL-8XT headphone amp. It was supplied with a pair of 6N13S power tubes, and two pairs of driver tubes: 2 x 6H8C and 2 x Psvane 6SN7 (shown in photo). I'm really keen on purchasing some new tubes to play with the sound. However - I don't understand the naming or...

I've just been told on another forum that I shouldn't use both the RCA and XLA outputs at the same time, as it will split the power and degrade the signal. Is this true? I've always had an amp plugged into each output simultaneously (tube amp into RCA and SS amp into XLR). As a test, I just...

To be fair - I haven't noticed any noise or interference whatsoever using my Android phone. It's as clear as a bell. I just wondered if other sources changed the sound. For example - could my PC give a bassier sounds, or more spacious soundstage?

I run my Android phone (Pixel 4 XL) straight into my Ares II with a USB-C to USB-B cable, and play music from Qobuz (through the USB Audio Player PRO app). My question is this - would using a different digital source (my desktop PC for example) make any difference to the sound? I assume not -...

Damn - the cost of the washers would just push them out of my budget.

Completely agree. I've heard many people say that the DAC only makes about 10% difference to the sound - but I feel it make as much difference as the amplifier. In fact, the difference between using my phone's own chip DAC vs the Ares II is more noticeable than changing between my SS and tube...

I was as skeptical as the next guy - but I tried it and it really did make a difference. It's logical that a device generating an analogue signal would benefit in resonating freely. This is actually part two of his videos on tweaking the Ares II.

Don't forget to also tune the Ares II...

I've had mine about a month and it sounds better every day. No need to leave it playing - just let it happen when you enjoy them. The best thing I did was to pair them with a Denafrips Ares II and a high quality tube amp. I couldn't recommend this combo more highly. The Ares II gives the...

Are these still available?

Agreed!
