Need help to choose good speakers for my Yamaha-610 II amplifier

[yozhek]

Hi, all!
I've got an old Yamaha-610 II amplifier and 2 very cheap Toshiba speakers. I'd like to change these speakers, but I'm unable to choose something good. Can you please give me some advice?
I was thinking about Energy Speaker Systems RC-70 Floorstanding Speakers.
But I'm not sure it'll be good with my amplifier.
I attached amplifier's specs, maybe it can be helpful.
Thank you!

Why aren't you able to pick speakers? The Energy do a good job an would probably b a good match as well for your amp. Wharfdale is another to look at. There are so many options, do you have a price range, type of music, how loud do you listen and your room size may help to narrow things down.

I talk about Energy speakers because it's on sale. But I'm not sure that new speakers Energy will be good with my old ampli. I'm not sure because I understand nothing in specs: watts, Ohms, Khz... So I'm asking help.
Usually I listen rock (Pink Floyd, Doors), classic, Latina (Caceres, Buena Vista). Not loud. My price for a good pair of speakers - 1000-1200.
Room size now is about 9' x 20', but I'll move.
Thanks!

The Energy will work fine with your amp, the age of your amp doesn't matter. Specs aren't that important, as long as you feed your speakers a clean signal all is good. "Clean" meaning you don't over drive your amp past what it's capable of, don't let it distort.

Are there other brands you have access to?

I would consider Monitor Audio RX-6, PSB Image T6's or T5's. The Wharfedale 10 series considering the type of music you like, but speakers are very subjective. The PSB's are a very forgiving speaker of poorly recorded harsh sounding music. I imagine that the Wharfedales would be too. They tend to have a warmer, more laid back but detailed sound. I think that any of these would be better than the Energy's which are a decent speaker.

[Mr Peabody]

The Monitor Audio would be pretty much the opposite of how Blackraven describes the PSB, Monitor has a lively or vivid high end with good bass punch. My guess the MA would sound pretty good with the 610 but with electronics that already have a pronounced high end the MA can be a bit too much.

I know PSB brand, it comes from Canada. Someone told me that PSB Symphony Two are incredible. But a little bit expensive for me.

I live in Montreal, so I have access to all brands available in North America.

I just noticed your amp is 50 watts into 8 ohms, this would power the speakers suggested to a decent level but if you like to crank it on occasion you should stick to speakers rated with a sensitivity of 89dB or better. The sound isn't for every one but you might want to give a listen to Klipsch which are very efficient, meaning they play loud with not much power input, they typically have a sensitivity of over 95dB. Using horns they have a certain sound, some love them and they have a huge following while others turn their nose, so I'd suggest a listen first.
