buy an AV receiver (denon x2100) and the specification sheet says (AC 230 V, 50 Hz, 500 W) if I buy the tranformer 750w is good, or should I just buy the 500W? thx

Nope. It is better to buy something that is rated higher. In case there is a need of higher power consumption. Besides, it is better to be over-rated then under in such scenario and prevents any of this eletrcial items from burning out. :)

If AC receiver is 500 W and will be used continuously, then its better to get 750W transformer.

I have the Denon AVR-3313ci with 125w per channel...these speakers are working very well. I'm very happy with this purchase.

Well, I'm not an expert but I did some research to buy this excellent center channel to a Denon receiver (3313CI). As far as I understand, you need to check the nominal impedance of the speaker and compare with your receiver (the receiver spec will give you the range of impedance accepted). Besides that, this speaker handles up to 200 watts of power (it's powerful). So, you'll need to check the receiver spec also and compare. In my opinion, the receiver must deliver at least 100 watts up to 150 watts to be well fitted. If you get a receiver that delivers less than 100 watts, you can try to find another center channel less powerful (something like 150 watts max). That's it!! I hope it will be helpful!

You'll need to buy a digital interface that will accept a Toslink input and output analog connectors that your AV Receiver will accept...unless you AV Receiver has an optical digital (Toslink) input somewhere on the back...which it should if it's not too old. I send the Toslink output to digital interface that converts it to coaxial digital output (bought on Amazon) and then on to a DAC that accepts the coax digital...said DAC then outputs with red and white analog outputs that go to my preamp (AVR for you). Check the back of your AVR and see it there's a optical digital (Toslink) input. Good Luck JM

@Braintree fan. The step down transformer you used is for transforming the voltage from your source but it does not mitigate issues on fluctuations. The output of your transf. is dependent on what the input characterisitcs are which is taking from the raw power. In the event their is a drop or excess of voltage from the source (your socket outlet) your output also respond. That means your Onkyo will not be protected in such situation. My advise is buy an AVR (Automatic Voltage Regulator) that has an output of actual reading of 120V. Basically, the AVR you will see in the market are having 3x220 V + 1x110V. The TX-NR609 has a max. power consumption of 744VA. If you have other 120V appliances i.e. TV or blu-ray player you need to add those consumption to the 744VA. The new AVR now has spikes, sags and surge protections aside from the overvoltage & undervoltage protections. NOTE: when you size the AVR, the 110V legs is half of the capacity of the AVR. Let the store measure first the output voltage reading before you pay for it. If your source is 230V then you will get 115V output on the 110V socket. If you have 240V source which is excellent then you will get the 120V output which is healthy supply equivalent to your appliances. 115V to 118V is already tolerable, your 609 can handle it. You know the latest models now are computerized they have microprocessors and they are sensitive on the source you supplied to them unlike the previous ones. Here is the Computation example before you buy an AVR: 1. Onkyo TX-NR609 = 744VA 2. TV 120V say LED 55" = 228VA 3. Blu-ray Player = 14VA Total = 986 VA x 2 = 1972 VA You need to buy = 2500VA or 2000W. This rated capacity already considers the internal losses of the AVR. If your appliances is only for the 609, then you can adjust the capacity. Be carefull in buying the rating of the AVR, The VA is different from the Watts. When the storeman will tell you that it is 2500W do not believe on him. check if it is written in the AVR 2500VA, then the wattage cap. is only 2000W.

I was considering these as well. Interested to see what others post. Here is my research has yielded for 7.1 systems with Dolby True HD and DTS HD audio. A lot of people worry about upscaling, I only have blu ray player, so not much need for upscaling. Few do upscaling very well according to my research. Sony STR-DN1000: Nice HDMI connectivity, cleaner look, 100 watts per channel at 1% THD. I've heard upconversion is poor. $330 Sony STR-DH800: Does not upconvert analog sources. 100 watts per channel at 1% THD $250 Onkyo RC-160: Upconverts only to 1080i. 80 watts per channel at .08% THD $330 Onkyo SR-607: Upconverts to 1080p with okay quality, 90 watts at .08% THD $400 Pioneer VSX-919AH-K: .05% THD at 120 watts per channel, just 3 HDMI inputs, no upscaling capability $400 I realize these are Audio/Video Receivers, but it seems to me the main goal of most of them is for superior audio. After all, many TVs do a decent job making SD sources look better, even if you have to run an additional cable or two. To me, everything is going to be HDMI based, so I am leaning toward the Pioneer due to better power and less THD. $400 is very much on the high side of my budget. So if I decide to go with a cheaper receiver, I'll probably go with the Sony STR-DH800.

The answer to your question does really depends on what you are looking for. I certainly recommend evaluating your needs in an AV receiver. For instance, forget all about the bells and whistles of marketing but review it from your need. Example, you might not want a 4K pass-through capable receiver if you don't have a 4K capable TV, etc. Less features will often save you some money and get an older model too. You don't need the latest and greatest. Sorry this didn't answer your question but what I recommend might not be applicable to you, therefore, search amazon. :)

It depends on the version. The US version is 110 only and the European version is 220 only. Reconsider your decision if you haven't bought it yet. Mine stopped working after 6 months. There seem to be a common problem with the amplifiers of Onkyo receivers. Check the internet.

I am currently using it in a 2.0 setup. A very nice menu makes it easy for initial setup. This powers a pair of definitive mythos towers nicely. Also, the 4k pass through will be valuable in the future as well as the current pass thru without the amp even powered up if you just want to use your TV speakers late at night. Can't help you with the cutoff though... Not sure of all the preamp outs except the sub. This is prosumer level... The manual should specify.

Stephen G., I'm interested in connecting 2 receivers and switching between them. I have a modern home theater receiver (Yamaha RX-V477) and a vintage receiver (Realistic STA-76 circa 1975). Each one does some things better than the other and I want to easily switch between them depending on what I want to do (like play vinyl on the vintage) and watch movies on the home theater receiver. If you know of something that can do this, please let me know. Thanks.

I am using a Denon AVR-1912. While Denon no longer makes this particular unit, it is more than able to drive the KEF. When looking for a new AVR, look for qulity over gimics. Sony for example will boast high wattage per channel. They know that people often equate watts with powerful sound. Sound is not measured in watts however. Watts measure the amount of electrical energy used by a device. Getting a high wattage AVR might sound good but it only means it will cost more to use the unit, with little to no gain in sound. Look for a unit will a nice amperage. Harmon Kardon for example uses low wattage but has the amperage to drive beefy speaker drivers. That being said, I would reccommend Denon, Harmon Kardon, Onkyo is good too. For fun, look at the Sunfire....oh to have 4k to drop on an AVR. Stay away from Sony and yamaha. Sony devices struggle to handle high volume loads. Yamaha don't often drive the speakers effectivly. Other than that, look for good fetures; lots of HDMI inputs, one output. 3D is nessisary if you want to run 3D Blu-Rays. 7.1 is nice, although very few movies can use it. That will change, why not prepare for the future? Internet connectivity is nice too, as there are moble apps that will let you control the unit from your tablet or smart phone. Remember you get what you pay for, a good rule of thumb is the more buttons and dials on the face of the unit, the less there is under the hood. A good AVR does not need all the face plate eye candy.

I have used a Denon which is great but I since have upgraded (needed HDMI )to Onkyo and I like the sound that the Onkyo delivers a little better. I used the same polk speakers for both AVR'sThe Onkyo seems a little more bright which I like....sounds more crisp but some people don't like that crisp sound.Both brands are work horses so you can't go bad with either. Onkyo's much higherend Integra is nice also.So

Thank you, I too am wonderng at the difference between the two. I've got an older Denon receiver(3803) and would rather not have to replace it. This model seems to fit the bill for me.

I have a Denon AVR X3000.These are power hogs, but excellent, all the bass youhave ever wanted. If you are running a lowerpowered amp, best talk with Cerwin Vega, as their documentation is sketchy beyond peak handling of 400 watts.

Just hooked up to a Pioneer AVH-X2700BS, and it works perfectly. Always check reviews for the note that says "Verified Purchase". If that's not there, then they are not writing their review based on any actual experience with the product.

They sound amazing. We are using them for some music recording. Before we got a dedicated amp for them, I used an old Pioneer receiver that we had to power them. They worked fine w/ it. I'm sure your Denon won't have a problem.

I have these speakers connected to the Harmon Kardon AVR 2650. I would say it's a middle of the road receiver, but performs very well. The type of AVR you go with will depend on what speaker setup you plan on (5.1, 7.1, 7.2, etc), so it's more of a personal preference. I also, have a pioneer that I've had since the early 2000s and have nothing but good to say about it even after all these years. I'm sorry if this wasn't too much help, but I don't want to give you a line of B.S. because I can only speak from my experience with my receivers. Good luck, and if you have anything else I can be of assistance with feel free to contact me again.Kind regards,Chris I have these speakers connected to the Harmon Kardon AVR 2650.
