New tubes or new preamp?


I have an ARC LS15, and am considering either a set of NOS Amperex tubes, or selling it and getting a new preamp, such as an ARC LS27, or a Modwright LS 38.5.
As I'm unable to compare , what would you advise?.Will NOS tubes give me a preamp that compares with todays current ones, or is it a waste of money?
Thanks

Buy 4 tubes or a preamp that costs more than double the price of your current preamp is an amusing question. I think NOS tubes have become extremely overrated. If you want your LS-15 to sound its best you should send it back to ARC for a complete checkup and fitted with tubes selected by ARC. If you want an upgrade buy the LS-27.

I cannot comment on Modwright products.
"I put a NAD C162 pre-amp into this system (not my main system). It's my back-up pre-amp. The NAD is full sounding with good bass."

Did you leave the SP-9MKIII powered on all the time? If you did not leave it powered on you never heard it. So now you think the OP should dump his Audio Research preamp and get an NAD?

BTW, AR is Acoustic Research.
