There is a thing you could 'mode' and it should upgrade its sound without the doubt. Prima Luna, as well as many other manufacturers in such and even in higher class use Alps volume control. It is in fact the crucial and weak link of many preamps or integrated amps. By changing it, for some attenuator (Ladder type), let say from TKD, you will hear significant improvement that no tube or cable swapping can match, for a insignificant cost. Just be sure to buy the part that has the same values as the one inside and buy it from reliable source (not from Ebay and not from HK or China, as they are mostly fake, meaning not originals produced in Japan. Of course, it does not have to be TKD, but their TKD 2CP2500MC is a great value, performance/price vise. Its not expensive and you can always put back the original part back. Its not a difficult thing to do, for any experienced tehnician.
Is It Worh Modding An Amp
I have a Primaluna Dialogue One that sits idle as a backup. I’m debating the idea of having it modded. Problem is I have no idea what can or should be upgraded or if the amp is worth the investment. Id be willing to fork over 500-1000 if it was worth it and made sense compared to what else I could do with the funds. Curious what people’s experiences and thoughts are?
