Advice/Warnings for a newbie


Hi

I've had way too much free time and gone down a few rabbit holes purchasing some older gear, some of which I've got a little experience with and some none... but was curious, because I am not the best technically, if any of the more seasoned audiophiles might have any advice regarding my chain. I'm replacing my 30w Pioneer receiver with separates (put all my specs in the below list) – I got the preamp as a family hand-me-down and I've just bought the monoblocks (having service done now) so I've not heard it all together yet. The player and speakers I've been using forever. But will I OK in terms of matching impedances, gain, etc? Oh, and I'm installing a dedicated line for the monoblocks and was looking at a Niagara 1200 as power conditioner for the rest.... any tips greatly appreciated!

Yes, definitely put it together and listen for an extended time (weeks) before you buy more stuff.  The extra power from the amps should make a substantial difference in the sound.  I would have some kind of protection from power spikes (whether the Niagara or something else, maybe a power regenerator instead - make sure you have enough outlets, and not all of them are filtered on most units), and the isolated line is a good idea.  I have my equipment on a dedicated line and the voltage still fluctuates.  Looks like you upgraded the turntable where people mostly suggest (the tonearm), but you might want to look at a cartridge upgrade in the future.  Depending on what you listen to, a subwoofer (or 2) would fill out the bottom.  Do your tweaks one at a time to see if they make a difference you can hear, but have fun and enjoy your system, most of all!
I have a very good friend who is a serious stereophile. He confessed to me that he has spend at least $50,000 over the years, buying, selling, trading, trading up, etc. Of course his present system is terrific. He added that if he could start fresh he could put together an excellent system for about $15,000.  My advice, if I may...Take your time, learn from this excellent site and choose wisely.  
@millercarbon Greatly appreciate your advice. I understand your note on compensating for the analytical with neutral, that’s extremely helpful. And for the speaker sensitivity, this type of fundamental guidance is exactly what I was after. Cheers!

Thanks everyone. I’m definitely in no rush, (still only window shopping regarding power) but as long as I’m not going to blow anything up I’ll be enjoying the music!
