If you had to pick up just one set of tubes it would be ??

At this point, it would be the Mullards, but I haven't heard the Voskhods (should arrive this weekP) nor the recently received Sylanvias and RTCs.

I have Mullards, Siemens and my favorites the Voskhods

You'll like them

At this moment I would say the Telefunkens, but it's a tough choice. Voskhod's and Cifte's have both scored 9.5/10 on my personal rating system. Telefunkens 10/10 through the Hugo to the Pam Am (although I haven't yet tried the Russian tubes or the Cifte's through the Hugo first, so who knows, maybe they will sound just as good).

I'm listening right now to Mahler 1 through the Cifte's and it's hard to imagine anything sounding significantly better than this. This with LCD-X phones.

You are using the dac from Hugo and amplify with the pan am right ?

I'll get some telefunken first, and some yougoslavia to try this family of tall tubes (seem to glow nicely)

I wish I could try an amp such as Hugo but way to expensive for me

What sounding quality would make the telefunken 0.5 point better ?

Yes - I feed the Hugo with a digital signal and then output from the Hugo through the Pan Am amplifier. It's actually a bit of double-amplification, but the sound is quite good.

Not much difference - very subtle.  More like the overall feeling of instrument separation, detail and soundstage just appeals to me a bit more.

IMO to output through the Pan Am amplifier is fine to get a very nice signal and tube sound biggrin.gif
To feed the hugo with a cheaper dac and only use the amplification would be something else

The Hugo is an integrated DAC/Amp - the two functions are not separable.  So, you need to feed it a digital input and then the output is only available through the combined Hugo DAC/Amp.  So, you are "double amplifying" when you feed the Hugo output through another amp.

 

There is much debate in the Hugo thread about how this degrades the Hugo's sound.  I'm not really sure as I haven't done enough listening with this combo yet.  All I know is that the first time I fed Hugo output to the Pan Am, the sound was glorious - 10/10.  Maybe it was just the newness of the Hugo sound, who knows.

 

When I return from traveling and have some time, I want to try this again and feed the Hugo to the Pan Am, the GS-X Mk2 and the Liquid Glass and really see if additional amplification adds anything to the Hugo's sonic character.

hugo is 56 ohms / 320 mW so with pan am it's perfect and as long as you get the wow feeling wink.gif

More nuanced than that. The designer has only said he designed the Hugo for transparency. Adding an amp is adding colouration. Whether you enjoy the colouration i.e. stepping away from that baseline transparency is up to the listener.

So far the battle rages on between the Mullards and the Sylvania 6HM5s. The only differene so far is that the Syls are much louder at the same position on the volume pot. Both throw a very similar soundstage and signature. Thick dynamic lows, rich mids, and smooth yet detailed treble. I suppose I'll just be forced to listen to more Miles to help me decide. Oh the horror!
