Hi all,
Yesterday evening, I did one hour of serious tube rolling
And I came to the no surprise conclusion that it is very difficult for me
and my soon to be 67 year’s old ears to tell the difference
between my collections of NOS tubes.
During my tube rolling session I thought at times,
that I could hear a difference between some tubes,
but after several swaps I was not sure anymore.
However, I think the following tube give me the impression of being
a little better sounding than the remaining of my collection.
Maybe 10% better sounding, but again, not really sure
?
Raytheon 12AU7 (Thomas organ USA 1957) and
RCA 6AS7G.
From time to time, I will try again with other tubes,
just in case I can hear some differences, but I think not…
After complaining in several of mu posts about the Sennheiser HD650
being veil and dark, I guess I am now getting use to that kind of sound,
not that I like it, but I can live with it.
I am sure many could find my combo (Bottlehead Crack/Senneiser HD650)
very good sounding and I would agree with them.
If someone suggest to me the Speedball upgrade
or better tubes model and make, I have to pass, right now,
I have invested enough money on my headphones set up.
Thanks.
