I can agree with upgrading subwoofage, but imo you have the rest entirely backwards. I would absolutely put my money into speakers before amplification. Unless op is exceeding limits a new amp is just a lateral move. Speakers, by far, have more impact on sq than any other component in the chain. Solid state amps are designed with one goal in mind. Transparency and accuracy. It's very mature tech and by now the major players have it down to distortion levels so low that they all fall well below the ability of human hearing. Any perceived differences are just bias or placebo, provided everything else is equal and operated within spec.
I know this is an older thread but I couldn't let this one go... lol.
I appreciate your reply, and while you’re correct that changing the speakers will change the sound of a system more than any other component (not always for the better though), I don’t believe I have anything backwards here, and I’ll explain why I feel that way.
First, he is just looking to “upgrade” his system. He doesn’t say why though, maybe he has some extra money laying around, and he just wants something new. Maybe he’s unimpressed with the performance or sound, or maybe he thinks newer speakers will just automatically sound better because they’re new, we don’t know. What we do know is what components he currently has, so that’s what I’m basing my suggestions on.
Currently he’s powering his system with a ~ $500 lower to mid-range Denon receiver (AVR-1912), which is rated at 90 watts per channel. When you start running 5 or 7 channels off of a relatively lower end AVR like the AVR-1912 though, you typically end up only getting around 30 to 50 watts per channel (if you’re lucky). The Definitive BP30’s are massive towers, with four 6-3/4” mid/bass drivers & 2 tweeters in each enclosure, and they’re rated for 20-500 watts of power. These speakers
love power, and they can sound pretty underwhelming if they’re underpowered. It’s not that they ever sound
bad, as they have a fairly high sensitivity @ 91dB, but the more (clean) power that you feed them, the better they perform and sound. My recommendation of a 200-400 watt per channel Sunfire (or similar) amplifier would be a
massive improvement upon the (maybe) 30-50 watts his current AVR is feeding the BP30’s now. The difference in the way the BP30’s will sound with quality separate, high power amplification is most certainly not placebo or bias, it’s more like a game changer. Feeding a speaker 40 watts that sounds best with 150-200+ watts of power isn’t going to bring out the best in those speakers. Honestly, a low to mid range, low powered AVR isn’t going to make any speakers sound their best, even if it is from a reputable manufacturer like Denon. Nowadays, with all of the technology (along with the licensing fees for all of those logos), you can’t really expect to get great amplification from a $500 receiver, unless you’re buying from the used market that is. The BP30’s were Definitive Technology’s flagship speaker, they just require more than 50 watts to sound their best.
There are a couple of other reasons I didn’t recommend to buy new speakers. First, his budget is around $3k, and that needs to include a subwoofer (or 2). After having purchased a good sub (or 2), assuming he’s buying new, what is he going to get that will be a significant improvement upon what he already has? Keep in mind that the BP30’s are already $3000 speakers (adjusted for inflation), and from my experience (and opinion), they excel in a home theater setting. Sure, speakers are highly subjective to the listeners taste, but he never said he doesn’t like them. What he did indicate though is that he hates buying something and then returning it because he doesn’t like the way it sounds. Why not feed the speakers he currently has with the amount of power they sound the best with, and go from there? There’s another reason that I might advise against different speakers though, and that’s because the BP30’s are bipolar, and he’s probably used to getting that type of sound in his home theater. Monopoles are going to sound quite different, and they don’t really provide the same type of sound field that you get from bipolars. While I’m sure he could find speakers that sound good to him, he may find the experience a bit lacking in comparison to what he’s used to. When I switched to bipolar speakers in my HT setup, they provided a huge improvement, and it wasn’t just me that felt so, my wife commented on it before I had even said a word. I’ve run a ton of different speakers, including higher end offerings from Polk, NHT, Energy, Klipsch, Canton, Martin Logan, Bower & Wilkins, and Paradigm studio series, and the Def Tech bipolars simply sound better to us for home theater. They sound really good with music as well, but I do have a couple different 2 channel setups that sounds better, in my opinion anyway.
This is home audio though, and everyone has their own opinion on what works best and sounds best, and no opinion is wrong. Everyone’s rooms are different, and their ears and sound preferences are too. Home audio is a lot like food and beverages, we can all (usually) agree that some foods or beverages are “higher end” than others, but our preferences for flavor (or sound) profiles may not be in agreement. Are there better speakers out there, especially for 2 channel listening? Absolutely! I’m not saying that it’s impossible for him to find other speakers that will sound better to him, or that BP30’s are the “end all-be all”, what I am saying is that his current speakers are underpowered, and they will sound noticeably better if fed the proper amount of quality wattage.
If he had said he was unhappy with the sound of his current system, then I’d agree with you to change the speakers first. Changing speakers will absolutely have the biggest impact on changing a systems sound. You mentioned that a different amplifier would be a lateral move, yet the same could be said for speakers, and it may even be taking one step back if he ends up buying speakers that don’t sound as good to him in his room. In this situation though, his current receiver just doesn’t have enough power to make his current speakers sound their best, and they’re very good speakers if you provide them with enough power. He’s looking to upgrade, and new speakers may or may not be an upgrade to what he currently has, but providing his current speakers with 200-400 watts of quality amplification, as opposed to the small amount they’re getting now, will certainly be an upgrade. Once again, this is my opinion on what would be the best way to upgrade his current system. If he was running a Pioneer Elite SC-37 (or similar) receiver with ICEpower or D3 amplification and 135 watts per channel (5 channels driven), or a Denon AVR-4308 with 145 watts per channel (5 channels driven), I probably wouldn’t suggest adding an amplifier, and I’d probably agree with you and suggest that he try different speakers, or at the very least to make sure that he’s used the Audessey room correction, and tried some things with his room first, such as speaker position and room treatments.
