I went class D 5 yrs ago it is the best you can get period speed and clarity there is no crispy in the top end crystal clear and most acurate true to life reproduction of instraments 😮😊😊😊
What is the part no on that black ice power board . That looks like the 2023 new release parts express dont have .. where can i buy 2 1200 watt 2023 black ones ? Think those only come 700 n 1200 . Want to change out the 700 watt mono ice power in ps audio m 700s ty 😊😊
I guess you are talking about Icepower 2000AS2. You can purchase it from proven EU retailer Soundimport www.soundimports.eu/en/icepower-2000as2.html . They have it in stock and provide warranty services WW.
Hi, it depends on what you are aiming at. The amplifier stage is not the main design challenge. The power supply is. The difference between a good and a great amplifier is in power supply quality architecture. PA5 uses a mainstream computer-type power supply that is not designed for high instant current capability. I would recommend finding solutions with an integrated power supply. PA5 is expensive for an 80W amplifier. Purify design has 400W output. Working away from clipping is more important than THD figures. The key difference will be in low frequencies performance. Low frequencies are important for emotional perception and richness of music reproduction. Those 2 units are not comparable. Purify wins in all aspects, but to make a finished unit you need a good power supply, and those are significant costs.
Awaiting your next episodes in this series. I know you like ICEpower. If you were to start from scratch would you pick Purifi or Hypex Ncore over ICE for a DIY giant killer amp?
At high-end booths are equal. Absolutely great products in all aspects. If you want to build one and forever for music listening the sweet point is Hypex NC502 and ICEpower 1200AS2. Hypex NC502 can provide about 300W perfect sound in stereo mode with some headroom, ICEpower1200AS2 about 500W + headroom. It is hard to find a listening scenario when you will be short with power and quality. Practically you will never hit above 1/3 of power. My pick of ICEpower is business-oriented due to the larger lineup, especially in the budget range, not a quality consideration. Purifi is a bit different story. The company philosophy is to sell and license R&D technology, not the finished product. Maybe in the future, but today this company providing variations of reference design kit. There are no certified products in line up yet. Certification is important as well. Not for DIY, but in the professional market, you cannot sell anything non-certified. And certification is an expensive and long process.
My pick will be 1200AS2. I recently developed a prototype and the result is outstanding. Probably today it is one of the best performing amplifiers in the world. And price/performance is unbeatable. It is a true end game amplifier board with quality exceeding human hearing limits
I am building a 4 way speaker and planning to use ice power 4 300A2 amp and 1500s smps. I don't have electrical knowledge and can't make out how to connect rca out, banana plugs and connection between the above mentioned components and also main plug and power switch. Can you help by showing how to connect these using board pics
Class A is far more heater than the amplifier. Class d in theory is analog as well. It is pulse width modulation. The latest device's quality is incredible.
Thank you for taking the time to make this series of videos ................
Inspiring comment:)

What do you think about Topping PA5 vs Purifi and other class D amps? Considering one for my setup.

Have you looked at board Support materials There is PDF for download with pin legend and many more www.profusionplc.com/parts/icepower300a2
Class D is digital, class A is analog. Sorry but that will never change.
Class A is far more heater than the amplifier. Class d in theory is analog as well. It is pulse width modulation. The latest device's quality is incredible.
Digital is depending on resolution, analog is depending component & system precision...
