Hi pre65
Yes, I did many. Thanks anyway, but Not so good. Franckly. May be a matter of taste.

Indeed the smaller 85w version just delivers music, exactly the same one that Jules listen to and wasn't to keen on. To be fair to your amp guvnor I'm sure there were some matching issues with it in that system. |

Have The Temple Audios arrived yet Jerry? 
For old times sake.   |

Hi Jerry, I am very curious about these Temples. What amp are you waiting for? They are sexy, those litle T-amps.
I'm tempted by the Bantam.

Their TOTR amps - Monos with Supercharger PSUs.
They may arrive today, then it's 5 days of quarantine.

I have had the monoblocks for 6 years. I have 4 of them powered with two 12V 16AH LiFePO4 batteries. I am still very happy with the sound from them. Unfortunately, I had to send one back recently for repair as it started emitting a high-pitched squealing but John sorted it after a bit of to-ing and fro-ing. I'd like to try the Supercharger PSUs compared to the batteries.

The LiFePo4 can deliver enormous transient current but the Supercaps probably deliver it very fast.

My friend has tried most power supplies with his monos and now just only uses the Supercharger
If you can afford a pair I think you enjoy.

This can easily be surpassed with new power supply technology both in terms of transient current response and total noise floor reduction happy to demonstrate pm if interested

Tony you know the rules here. Next time I will delete the not so subtle add

I have tried many ClassD amplifier boards over the last 20 years or so. Some I have modded to death following the threads on Diyaudio. The first one I bought and the one that brought ClassD to the attention of the "Audiophile" community was the Sonic Impact cheapo plastic cased portable piece of "junk". Those with much better knowledge ripped the thing apart and found it used a Tripath 2024 chipset which they then modified to be used as a proper amplifier. The 2024 was said to have a 15w output, however in reality the power available without 10% distortion was around 5w. Now you would think that such puny power could not be of any use in the real world (valve amps excepted)....not so, these little things were a revelation and produced a sound that probably matched or in some cases bettered commercial amplifieres from the previous 20 years or so. How did they get such a sound from a chip the size of a postage stamp which was stone cold after a lengthy listening session? Googling will tell you if you don't already know how these things work. Fast forward to the present and there are now many iterations of ClassD architecture. I won't bore you with all the one's that I have or have tried. At the moment I enjoying a dual mono ClassD amp made with 2 mono IRS2092 boards. These boards were recommended on Diyaudio for their sound per £ value and they don't require any modding. They will take a balanced input and depending on the power supply are said to hit a max of 200w into 4 ohms (50v power supply) How much are these boards? I got mine for around £10 each, they are now much much more expensive...£15 - 20  depending on where you buy. If you can put together a simple Lego kit then you can make an amplifer. You don't need to populate the pcb's, just add a power supply...linear or SMPS as long as they will do at least 5A output, some RCA's or XLR's and speaker binding posts, IEC inlet etc etc and present it all attached to your finest piece of scrap plywood to make sure that it all works and that it works for you as an amp before making it look pretty.  |

That looks like a good project for someone
Thanks for sharing

Topping have brought out a Class-D Pa5 amplifier (125W per channel into 4 Ohms, 65W into 8 Ohms). It takes 2 balanced inputs (TRS) which would potentially allow me to dispense with my pre-amp - which these days is a glorified switch since I use my Gustard's software volume control. I have had good experience with a Topping D90 DAC and was wondering if anyone has heard one of these? The only review I have found is on ASR where it measures very well but I'd like to hear subjective views too. |

Try not to get too wrapped up in ASR findings. They don't listen to the equipment, which as we know is vital in getting synergy with the rest of your system. Try and borrow one or buy on sale or return basis.

Yeah, I hope Topping takes it up a few notches. More watts and offer them in mono blocks. That will definitely get my attention.  |
