    Class D

    I use a solid state relay with mine. This will only work if you have a 12v trigger output from the AVR. https://www.amazon.com/gp/product/B00RHBEDJE/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

    Scam? or real? ebay Khorn ads

    Definitely a scam. I saw this same ad over a year ago. I reported it to Ebay.

    Class D

    I recently purchased a TPA3255 paired with the recommended MeanWell power supply. I bought this combo to power a pair of RF-7ii. I'm new to amplifiers and have only used a Denon AVR to power my setup. I really like the sound of the TPA3255. There is a touch of "warmth" and the music just sounds more "well-rounded" than the AVR alone(I still use the AVR-x3300 as a preamp). I have a few basic questions and would like some input. So far I've spent around $110 for the amp and PS. The enclosure(yet to be purchased) with connectors appears to be about $200 for a total of $330-ish. What would a comparable class A or AB amplifier cost? I can only assume this combo of quality and power can't be touched for anything less than $600-$700-ish? I truly have no concept! Also, is there a way to utilize the trigger from the AVR with the Mean Well....perhaps just a relay? Does anyone just leave their's on 24/7? Thanks for any input, this thread has been great! Mark

    External Amp advice?

    I did run Audyssey and prefer it when listening to 5-channels. I don't notice too much of a difference in 2-channel whether it's on or off. Overall, I like the sound of my old Denon 3802 better than the new Denon-3300. Even though it's better, the bass and overall sound is still too thin. I expected more "slam". I've combed these forums for hours and the general consensus seems to be that the RF-7ii shine when they have real external power. I guess it could be my room, but it's far easier to change my "suspect" amps over changing room characteristics. Thanks for the reply!

    External Amp advice?

    The room itself is 16' x 24' with 9' vaulted ceilings. I sit roughly 12' feet away with the speakers being 10' from each other. I tend to listen to music at loud levels for short durations(I'm guessing around 95 db). My current AVR is fine for TV/movies but not so much for music. The music becomes "thin" when cranked up. Sad to say, as of right now I don't think there is too much of a difference between my old RF-3s and my new RF-7ii. I know the source/amp HAS to be the difference.

    External Amp advice?

    Thanks for all the replies, I truly appreciate it. I keep thinking that Class D is the way to go, please correct me if I'm wrong. For roughly $200 (minus the enclosure) I can buy a power supply and TI audio board that have some fairly impressive specs. The issue I have with any amp is that I really can't audition them first. My biggest worry is that I can easily end up spending $700+ and not really hear a discernible difference to what I have now ....and if this is a used amp, I'm stuck with it until I sell it(which can be a big hassle). The TI board I was looking at is $150-ish + $40-ish for the power supply. If the combo sounds great, I can then look for a decent enclosure, if it's bad, I'm out $200 versus $700+ for a "conventional" amp. Does this seem at all logical? Again, thanks for any input... Mark

    External Amp advice?

    I've actually looked at the "Class D" thread in the Solid State forum. I'm very intrigued by the Texas Instruments TPA3255EVM board. I'd like to know how this stacks up against the amps I've listed. I wouldn't mind doing a DIY amp if I knew the outcome would be worth it.

    External Amp advice?

    I currently have a Denon AVR-x3300w that feeds a RC-3 and 2 x RS-3s. I use the pre-outs from this receiver to feed an older Denon AVR-3802 that solely powers a pair of RF-7iis (I know this setup is rather goofy, but I wanted maximize the power to the RF-7iis). The two options I am looking at is a used Emotiva XPA-2($500) or a new Outlaw-5000($599). My main goal is to "wake up" the RF-7iis as they seem a little too "thin" running on the AVR alone. So I guess my questions are; Do both amps have ample power to run the RF-7iis and is one better than the other in terms of clarity, sound stage and instrument separation? Is there maybe a better option at this price point(maybe 2x Outlaw 2200 mono block)? Thanks for any input.... Mark

    Bitcoin ETF?

    You can use an exchange such as Coinbase. I've purchased fractions of a Bitcoin, Ethereum and Litecoin through them.

    Klipsch Forte III vs RF-7 II Review

    They're Walnut. I found the link in the "alerts!" section. They look better in person, I'm amazed by the fit and finish. They're supposedly new (not B-stock). Even if they weren't "new", they're flawless. They came with a free sub-woofer, free shipping and no tax for $1799. I'll probably sell the woofer to offset the cost a bit. I need a better amplifier, right now I'm using a Denon AVR-x3300w. I'm guessing they're probably at 80-85% of their full potential.

    SOLD Cornwall I $950

    I acquired the Cornwalls approximately two months ago from a current veteran forum member(who shall remain nameless unless he chooses to chime in:). They sound great, I'm just looking more for a home theater type speaker and have since purchased a pair of RF-7 IIs. These have been tastefully modded and there is currently nothing left to update or upgrade. Here are a list of updates/upgrades: Tweeters are set up with HF Elliptrac horns coupled with DE220 TI drivers, the woofers have been replaced with Eminence Kappa 15C, crossovers have been updated with new capacitors and are in the "B" configuration, all of the internal wiring has been replaced, mid horn has been dampened with Dynamat and new 5 way binding posts have been installed. I would rate the cabinets in good to very good condition. There are a few nicks and dings but overall they look very good. From 10 feet away they look fantastic! For pick up only. I'm located just south of Lansing Michigan. As the title states, I'm looking to get $950, the same amount that I paid for them. Thanks for looking!

    Klipsch Forte III vs RF-7 II Review

    Here they are.....so far I love them! Although, I now have a new list of "stuff" to buy; entertainment stand, bigger center channel, bigger/better amp!

    Klipsch Forte III vs RF-7 II Review

    I thought the EXACT same thing when I auditioned these two about a week ago. Both are great, it all comes down to the type of music you listen to. I just received my RF-7 IIs today!!!

    RF 7 II/RF 7 III/Forte III

    I guess it goes to show you that speakers need to be heard for one's self. Based on the forums here alone, I would have EASILY bought the Forte III's over the RF-7 II's. I just got back(10 minutes ago) from listening to both the Forte III's and the RF-7 II's. Both speakers were on quality tube pre-amp/amps. There were 3 of us listening and all 3 of of us picked the RF-7 II's...hands down. The Forte's sounded good, but not nearly as good as the RF-7 II's AND the Forte's were $1000 more! When it up comes to the upper echelon of Klipsch, convincing someone that one is better than the other is like trying to convince someone that vanilla ice cream is better than chocolate. I would be happy with either though.
