Your thoughts on my plans..


After reading through some of the forums, I might be a bit under developed for this forum, but I was invited after buying a Era Gold mk.V with PSU1..

I am setting up my first phono system and the only real experience I have is many decades ago with my fathers technics ?? turntable and Teac amplifier.
I have some disposable income, but am not wealthy and didn’t want to spend a fortune to break into this world right away.. I think I’ll likely inherit some of my dad’s record collection - but I’ll also be buying newer albums to listen to. My music taste is fairly eclectic with more emphasis on country (think Chris Stapleton / Eric Church) and folk (think Mumford & Sons / Lumineers).

I have purchased a Pro-Ject X1, GSP Era Gold mk. V with PSU1 and Martin Logan Motion 40 speakers.. i plan to amp through either my Sonos Amp (125w/ch) or my Yamaha A1010 AVR (110w/ch)...first choice being Sonos so I can also stream to other speakers around the home...although I’m open to buying a dedicated amp and if neither of these do sonic justice. Besides the two amplifiers, I’m still waiting on all to be delivered..
I’ve read through the forum a little tonight and feel my system is undeserving of being here, but thought some of you might have an opinion on my choices so far and if you think I’ve made any poor life choices so far.

If they state that the speakers are 4ohms, then it's 4ohms "as connected to the amplifier".  So if you disconnect the two circuits at the terminals, then all bets are off for what impedances each will independently present.  They could be 8 and 8, or any other combination that sums to 4 when run in parallel.
Looks like you're off to an excellent start.  Just be careful running a second set of speakers off your AVR.  The same amp will be driving both speakers, so if you've got two 4 ohm speakers, that'll be a 2 ohm load for the amp, and the 4 ohm spec is average.  You could be down to a single ohm at some frequencies. 

Many amplifiers struggle to produce the current needed by that low of a load, and while it may "work", audio quality is likely to be effected.  Distortion will likely increase substantially when the amp is taxed in that way.  

I also agree with the folks suggesting a trial of a dedicated 2-channel amplifier.  You might look around and find a few with a good return policy (music direct, apos, etc) and then demo 3 or 4 contenders at the same time.  You'll learn a lot about what the speakers sound like and get a sense of how sensitive they are to different amplifier flavors. Just choose the best and return the rest.  Maybe you'll get lucky and find out that your Yamaha or Sonos was the best option anyway.
