![]() So far I've been quite happy with the build and have even done another one (with a 50ASX2SE). The sound is very good overall. The bass isn't quite as hard hitting as the Emotiva (it is a lower wpc rating after all and the Amigas are quite inefficient) but the top-end has amazing clarity and I notice details that I've never quite gotten so clearly before. Even driven quite hard the amp barely heats up and distortion is minimal, though I'm sure I'll run into it sooner vs. the Emotiva if I go further. Assembly was quite easy and took me only a few hours for the first one. The Ghent Audio chassis are quite nice, though the faceplate had a nick on it. They were happy to send a replacement for only the cost of shipping ($6) and all was well. The wiring harness was 90% configured correctly - you only need to do a few instances of soldering wires together to finish it. My only wish is that it had 12V trigger built in or a standby mode, but these aren't terribly hard to add and I'll probably figure out how to do this next. The next stage here is using this and the 50ASX2SE with a MiniDSP to set up a pair of active speakers using the TangBand W6-2313. I'll post here once that build thread is up. |

A few tips: 1. Buy the wiring harness with the case from Ghent Audio 2. ALSO buy the wiring harness kit from Parts Express as well This way you have the best of each set and can use the right one for the situation. The 123Toid video is only an overview, so you'll want to reference the manuals/datasheets on parts-express.com to make sure you have things wired up correctly. Enjoy! ![]() |

Here is the first amp. I haven't received the second case from Ghent yet even though I ordered them at the same time...
Decided to forgo the switch and RCA input, as I don't need them. limits |

Very nice work, congratulations!!
May I suggest you don’t cut the unused wire, you might need them eventually (ex +/- 12v supply output) BR Eric

As an FYI you can order express shipping from ghent. Usually gets you a week shorter shipping for only a few additional $. |

Yesterday I just finished the case of my little bluetooth amp.
Its the electronical part on an Sony SRS-BTX300. So it has bluetooth standby fir only 0.1W power consumption and a 2x10W Yamaha YDA174 chip. Sound really good on my Canton Vento 820.2 Last edited by hansueli; 15th October 2019 at 09:45 AM. |

Next amp.
6 channel IRS2092 with 36V power supply and PT2325 volume control. Amp will be feeded by Teufel DecoderStation 5. I will put some relay for bypassing volume controle on-demand like Yamaha Pure Direct. Amp is based on IRAUDAMP5 with IRF6645 mosfets. I will put some additional capacitor later. Power supply looks to be enought for powering this amp easily :-D |
