Bad idea? Yamaha CR-200 with 4 ohm Smaller Advents

[Pablo77]

I'm running Smaller Advents through a Yamaha CR-200 in a small room (home office) at moderate volumes. No second pair of speakers.

First off, on the back of the receiver it says that 4-16 ohm speakers are acceptable with a single pair of speakers, but only 8-16 ohms when 2x pairs of speakers are used.

The man who fixed up the receiver and sold it to me, and is knowledgeable, recommended not using 4 ohm speakers. I've seen a similar recommendations on this forum.

BUT - the Yamaha plus Smaller Advents sound great together - much better than my 8 ohm speakers (similar vintage Altec Lansings or Missions). Something about the more power-hungry speakers turn the Yamaha's flat sound from somewhat boring to quite exciting.

In a way this seems logical, much like how older receivers (at least the ones I've owned) often sound better and don't cut out at higher volumes. The low volume seems to make them struggle.

My questions, then:
1. Has anyone every actually damaged a similar receiver using Smaller Advents?
2. Am I likely to feel the receiver getting hot before encountering problems? So far it doesn't seem to be running noticeably hot...
3. (Sorry if this is a stupid question). Will plugging my turntable into the back of the amp, as opposed to a separate plug, make any difference in this situation?
THANKS!

Welcome to A.k.!

4-16 ohm speakers are acceptable with a single pair of speaker

IMO This implies modest levels.. no cranking the vol. too high (no kids abuse etc) and assure good air circulation.. I never use amp AC outlets; switched or unswitched., I'd keep phono AC separate anyway.

the reason for this is that when you add a second pair of 4 ohm speakers, the overall impedance presented to the amp is less than 4 ohms, which could damage it. if you stay within the specs, and the reciever is in good repair, it should be fine.

plugging the turntable into the switched outlet on the back should not affect any of the above, but you should certainly be sure that you're not exceeding the allowed current on the outlet. i cannot imagine that your turntable will exceed it, but worth checking anyway.

I'm not opening a can of worms and sure no issue AC wise. I was more focused on keeping the phono AC cord away from the amp. many mfr's recommend that anyway and there have been several threads on that here moving the TT away from the amp. : Just splitting hairs .I just never use 'em.. enough cables the back anyway... no issues?. go for it.

i completely agree - you ARE splitting hairs, lol

i am also an advocate of keeping one's AC cables and signal cables far apart - as for specifically keeping one's turntable away from the amplifer, i can't comment - i'm more of a digital guy

I think you will be fine with all of the above....as someone else suggested just take care with the volume.
