    I suppose you hate the word tube as well.

    Ha - in Glasgow 'tube' [pronounced as 'choob'] has a rather different meaning! In that respect, 'choob rolling' could be very interesting...

    The original Siemens [IMHO] are by far the most "Right" sounding of the ECC88,E88CC,7308, 6922 Variety.
    But, as others have said, it will depend on your taste, and system setup, be careful of NOS versions, as all the variants of these valves tend to suffer badly with noise issues, [they werent paticularly designed for Audio purposes] so, be sure they have been tested properly!
    Good luck on your quest!

    I do! and "rolling".... We're British FFS!

    Also PCC88 is not really compatible with ECC88. It has a 7V heater as opposed to 6.3V so whilst both will work it's not ideal. For optimum performance and reliability heater voltages need to be fairly accurate, believe it or not...

    As Anthony said the ECC88 was not designed for audio use (VHF cascode RF amplifier is its intended use) and so they are not really tested/graded for low audio noise. They can be one of the lowest noise valves in general use but you will find lots of rogue noisy ones around which, whilst they make the grade for their intended use, are way too noisy for the first stage of a phono stage for example. "Good makes" can be the worst in this respect (ie that out of say 10 valves 3 may be noisy) and Russian ones often the best as far as consistently low noise IME.

    I could think of a few suitable candidates, some of which would cause a bigger rumble than others!
