High end Class D amps?
Just an observation and a question. Are there 'high end' Class D amps out there that are just as good as Class A, A/B amps? I realize that's a sensitive question to some and I mean no disrespect---but whenever I see others' hifi systems on social media, all of the amps are A or A/B. There's always Pass, McIntosh, Moon, Luxman, Accuphase, etc. Where are the Class Ds? For folks out there that want more power for less efficient speakers and can't afford the uber expensive Class As, A/Bs, what is there to choose from that's close to those brands? Thanks

I will throw and old dog a bone ... namely I will throw you a bone George. Explain, in detail please, exactly how EPDR impacts the ability of Class-D amplifiers to drive a load. That is it, that is all you need to do. I am 100% certain you can't do it correctly, but here I am, have the floor, grab the bone, and show everyone you are the expert. Tell us exactly how EPDR impacts a Class-D amplifiers ability to drive a load. |
I haven't heard much discussion on this thread thus far about the newer Bruno Putzeys designed Purifi Eigentakt class D modules that outperform his previously designed Hypex NCore NC-1200 modules, both in measured performance and subjective listening, according to this 6moons review linked to below: https://6moons.com/audioreview_articles/purifi/ I think these modules are available to the DIY amp building community that previously often utilized the Hypex NC-400 modules, companies that configure or assembled these newer modules in modest custom cases for sale at reasonable prices just like they formerly did with the Hypex NC-400 modules and regular established OEM audio amp companies that previously used the Hypex NC-500 and NC-1200 modules in higher quality custom cases for sale at higher, typically $10,000/pair plus prices. In the 6moons review, Bruno Putzeys stated many of the established amp manufacturers like Rowland and others plan on using the Purifi modules in new upcoming top of the line models and continue to use the Hypex NC-500 and NC-1200 modules in current amp models, that will be then positioned as their 2nd and 3rd tier models. I also haven't heard much discussion on this thread thus far about the newer Orchard Audio BOSC, now renamed the Starkrimson. These class D modules/amps are interesting because they are offered for sale at only $1,500/pair, they're offered as either just modules for the DIY community or in very small and modest monoblock cases just like a normal finished audio component product, they measure extremely well and they utilize the newer, very fast switching, GaN output transistors. I believe Orchard Audio designs and builds their own proprietary class D modules and that these $1,500/pair monoblocks are currently the least expensive available class D amps utilizing GaN transistors. Here's a link to a recent class D article on the Audio Express website that's titled "Fresh From the Bench: A Tale of Two Class-D Amplifiers Orchard Audio BOSC and Purifi Audio Eigentakt EVAL1": https://audioxpress.com/article/fresh-from-the-bench-a-tale-of-two-class-d-amplifiers-orchard-audio-... It's important to note that both of these modules are a further advancement of the currently available solid state and analog class D power modules technology that accept only analog signal inputs and have regular high-level speaker outputs . These need to be distinguished from the newer technology of digital class D amp modules that will accept only digital signal inputs and have high-level speaker outputs, which are typically referred to as 'power dacs'. These power dacs are likely to become more prevalent in the near future, possibly in new, non-traditional 'integrated' combinations of functions in a single chassis or even digital interconnects to speakers powered by one or more power dacs. Class D continues to improve at a relatively rapid pace and new paradigm shifts are not only possible, I think they're probable. |
Find out yourself sunshine, why should bust my ***** trying to explain to a brick wall. There’s plenty to read here. Educate yourself, 3 pages of it. for you to "try" to understand maybe? https://www.stereophile.com/reference/707heavy/index.html |
