New tubes for Conrad Johnson17LS Pre


Sigh... I know tube rolling has been discussed to death, but perhaps thats because it's a complex subject with no right answer (are'nt they all). Some say NOS tubes are snake oil and probably used anyway, others that they are indispensible. If there is a consensus it seems to be that the answer is equipment and system dependent. I use a Shanling CDT-100 and have found benefit in changing to Western Electric valves.
I bought the CJ from an Audiogon ad of course and am very happy with it. I use it with an LP12, the Shanling, an Aleph 3 Power amp, Living Voice Avatar speakers and Acoustic Zen cables. My query is, can it really be improved by replacing the Electro Harmonix 6922 valves supplied as stock and if so, with what? I do'nt really expect a consistent reply, it is too subjective a question, but any pearls of wisdom would be appreciated, thanks

Hi David12,

I talked to CJ about upgrading my 17LS to the 17LS2. Like
you I was interested in this as well. Unfortunatley the
the quote I got was near $2K. Considering that the new
17LS2 costs only $500 more than the original its hard
to justify the cost. For what its worth the dealer I purchased my 17LS now has the 17LS2. According to him the difference is very subtle.

Hope this helps
