What is the Holton Nxl 1200?
I can't find information about them.
maybe you meant Hypex?
This is an unacceptable workaround. Perhaps these modules are just marginally stable and the similarity to the First One modules is not just superficial. Or there are flaws in the way they have been wired up/grounded. These don't seem to appear in the current line up, or at least i don't see them

They are very helpful. Connection between the Receivers power ground and the Amps power ground is nessacary. Otherwise there will be hum. The board need 2 x15 vdc.
Not saying they don't help, only that for an amp which is reasonably stable such help is not needed. And any such add-ons only reduce the transparency. Quite unacceptable.
Are you certain the Holton modules are properly grounded? What does the manufacturer say? I find it very unlikely that they sell a defective product.

Nice stuff they have but I have a feeling that assembled boards on Virtual Zero are bit overpriced
I made I lot off Holtons. Only this NXL 1200 has problems. I sent them for mods to Australia ( moduls) but now I have modified them further after his advise. So maybe the receiver is not nessecary. But now I got them. So I keep them. Uses the That 1206 with only 4 transistors inside. I would never use an IC. 1200 is the only amp from him with SE in.
You can save money by solder them - I did. But not easy with smd. I do not think it is overpriced.
He do not sell them anymore and they where very costly. About 14000 DK.kr for two boards. 24 X 2700 uf on each board.
Probably any kind of input buffer would work equally well to keep the amp stable. Still, unacceptable behaviour, especially for an expensive amp.
I am beginning to think that the semi diy "modules" market is now offering much better returns to manufacturers than the finished products.

.... and what about sound quality .... compared with FO L. ( a working FO L 🙂 )

Very different in bass. Holton is more powerful ( more mosfets). First one is more tight ( Better drivers). Holografi is much better on First One. Bad Quality Cd is worse on First one.
.... and what about treble. Holton's are more aggressive or not ?
Depends on a lot. How you make your supply, and small amplifiers are more aggressive, then bigger moduls. I really do not like the moduls with Single die Exicons. Prefer the Dual die versions.

Sooo...
6 L modules sold... Sad to let them go, but i kept 2 of them for my own. Have to find time to build an amp with them.
Also i have 10 of damaged M modules.. I hope to fix at least two of them, because i have everything to hook them up.
Well i have everything for 10 of them, but no 6 channel madness now..
I may be able to catch Andreys partners in the up coming high end shows and have a chat. We will see.
