OOPS! Looks like I missed a post. Couldn’t wait, HUH? No surprise! I think I mentioned, in the note I enclosed, they might sound strange, before they’ve been played for a few hours, having been in a drawer for seventeen years. I don’t think the EH tubes were from the factory, but then- I can’t swear to anything ARC’s done, since the early 90’s. They were using Sovteks, back then. I always thought EH tubes kinda zingy, but- that’s just my opinion and you know what they say about those! Your welcome/have fun!
Tube Rolling for Pre-amps?
I have an Audio Research LS-16 that feeds a Madrigal Proceed HPA2 solid state amp.
I did not choose this equipment; it was given to me. From what I can tell the original owner spent a good bit of time matching up these two components with the speakers, Aerial Acoustics 7Bs.
The tubes in the AR are original. Probably 10-15 years old? But with an extended period of not being used.
The system sounds good to me. I don't need to change anything.
However, I've been told that the tubes are old and may need to be replaced soon. I've also read a little bit about tube rolling but most of the articles I've seen talk mostly about tube rolling with amps and not pre-amps.
So I have some questions:
1) If the original owner wanted a system that sounded like a 'tube' system, why not have a tube amp and pre-amp? Does it make sense to have a tube pre but SS amp?
2) Other than outright failure, how will I know if my tubes _need_ to be replaced?
3) With a SS amp, will changing tubes in the pre-amp have a noticeable impact on SQ? In other words, is tube rolling for a pre-amp played through a SS amp a thing?
4) For someone like myself who is happy with the system and who is also easily frustrated by A/B testing is tube rolling the pre-amp even worthwhile? I can almost always hear a change when comparing various components but only rarely am able to say A is better or worse than B.
( I probably can't even articulate effectively what I look for in terms of SQ except that I like the bass to be tight, precise, well defined and not boomy. I do not like the music to be overly bright or tinny. I like depth and lushness but not overly warm. Not sure if these are things you alter with tubes.)
Thanks for any advice.
