I have no idea if this model is from the current UK range, but a quick pricerunner search reports £250. Retail price is £400.


Yamaha av amps are good budget amps, don't connect anything to difficult a load (4 Ohm or speakers with less than 88dB 1/W m sensitivity)


1) I think you're getting confused with wattage. Buy the most powerful amp you can, especially when it comes to Yamaha (no way that Yamaha can output 116W x 6. More like 35W-45W x 6.


Yes a sub will make a big improvement, even those with floorstanders builtin. Buy the best sub you can. What speakers are you going to connect to the Yamaha?


[edit]- Richer sounds have the RX-V550RDS for £300, with a few last to spare. Usually RS sell off previous models, so I would guess the RX-V560RDS will be released soon.

With that £100-£150 BUDGET I would suggest spending those on Left/Right pair or Left/Right/Centre package, and not a full 5.1 audio system. You won't get anything decent for £150 for 5.1, at best something of pretty dire quality.


A set of Kef Crestas 1 for L/R and Cresta C for centre and should do the job and sound much better. Should be able to pickup second hand for £150 for all three. A couple on ebay ATM.


I've owned a budget Yamaha AV amp in the past. They're good for the money. The amp sections are pretty weedy though (couldn't drive a 4Ohm centre)

Bring up ebay and search for "kef cresta" (I can't link to specific auctions) or do a google search. Don't go overboard with bidding, I think the Cresta C retailed for £90, whilst the Cresta one sold for £100. So take that into account of second hand prices.


You could browse here and get a idea what else is available in your price bracket..although if you're buying a pair, make sure you can buy the matching centre at the same time [IMPORTANT]

Since you're probably buying blind I guess there's not much point in giving you dozens of "possible alternatives" You probably just want a "safe" buy without too much audio charasteric that others prefer.


But there also some B&W on as well.

considering upping my budget so I can get a near top of the range set of speakers >>> I dont see the point in spending £150 for a half decent sett when I can spend more and buy a set which might last me life time.


how much more would you think I would need to upp my budget for a surround sett 5.1 ??

A decent set of 5.1 speakers are those at £1000-£1500 are as good as any, given your amplification. Again don't spend too much, as the Yamaha amp will be the limiting factor.


A good subwoofer will cost money (at least £500+), that'll obviously bump the overall price up.


"near top of the range" from a certain range will cost several hundred pounds just for a pair of centre, and probably the Yamaha be incapable to drive them.


Personally I would buy a set of £100-£200 speakers for main pair/centre/rears, and perhaps £500-£900 subwoofer (buy a great sub once) then maybe a few years later change the speakers & av amp (or buy a 5 channel poweramp to replace the Yamaha's own amp stages) for better sound.

hard to think looking at them that they would be that good >> read a few reviews and seem awseom.!!


only problem is mate I want something that includes satellite speakers + subwoofer.


have just spent £450 on top of the range dvd player (kiss 558) then £140 on that amplifier.


if I buy those kef speakers I will all so need to buy subwoofer + centre speakers. etc.


if you come across anything thats all in 1 mate let me no >> thanks for answering all my ???s and pointing me in the right direction !


cheers jamie

You're going at it backwards, dude. The speakers are everything, so you should have started there. £450 on a DVD player and £150 on speakers is a criminal waste of £. I'm with father ted. If you can't spend £450 on speakers, then just buy the front three and save up for the rest.


Good luck.

I agree with Fatbottom and DMF.


Other alternatives - entry level Tannoy, Acoustic Energy, Monitor Audio and Wharfedale.


But if you prefer a satellite 5.1 system right now, rather than buying monitors for l/r and a center (and adding rears and sub later), you can get the discontinued Acoustic Energy Aego P5 system on ebay or at your local B&M stores at closeout prices (around $399). The newer version is not as good.

Jamie,

I would go far as to say don't worry about the center channel right now and just spend your budget on the front left and right. Stereo is not that bad... You can always add a center, sub and rears when you have the money for it. This way it will be a much better system in the end... Just remember whatever front speakers you buy you will need to get the same brand and series for your center channel... The rears you can use a different brand, but some would not advise it.
