Upss, my apologies for not being more active. I am no familiar with the “ rules of engagement” for this forum. Yes, I notice that MC gave his valuable opinion and I really appreciate all contributions . I enjoy a lot the process of buying a new piece of equipment, for example, I have been searching information for every speaker you have suggested , mainly reviews , that increases my knowledge ( but no my hearing abilities unfortunately ). Fritz and Salk speakers were unknown to me until they were mentioned in Audiogon ; fantastic ! Love the concept of a man doing everything in contrast to the big companies that have funds to do research and development.
Last night I have another good feeling in these search . The primaluma pre-amp that a friend loan me , is connected to my McIntosh amplifier: I told my wife to spent a few minutes listening to ( a tidal master playlist fo classic jazz ), She is not an audiophile for sure, but I took her 5 minutes to notice something diferent and I was so surprised for her comment : " ….. that sound is like silk” , wow , now I know she wont complain when the Raven and chosen speakers boxes arrive home. By the way as you have notice I am not english fluent, I am an Urologic surgeon ( still very active ) living in a town in the Andes Mountains , Bucaramanga , Colombia, I know only two other audiophiles in our city to share the hobby , so , no, I do not have the experience you have even though I started reading , buying and trading gear at 15 years old. Thanks a lot , these forum is very interesting (and sometimes frightening )
