I‘m just seeing, i think i keep them

Did that transplant sometime back with my Melco. Do you happen to know if there’s an upper limit on disk size. I took a gamble on 4TB WB Blues which worked. Maybe 6TBs wouldn’t? DGP

There looks to be a lot of power reserve on tap - what are the amplifiers?
Is that a new Technics amp?Love the meters

“‘Nice to have’ and ‘need to have’ lists were sent to Armand… by request. Not unexpectedly, such ‘nice to have’ lists are considerably longer than the ‘need to have’ ones, so we crossed out quite a few items… they can be revisited later if needed.
Anyway – long story short, other variants than the ones shown were discussed and rejected, as alternative B turned out to be fully feasible! The solution is based on the Hypex Ncore NC1200 module with an SMPS3KA400 PSU (63V rail voltage), combined with various custom convenience features, extra safety measures, soft-start (1.6 Ohm is a bit of a nightmare to fire up…), and so on. Modules and accessories were purchased.
Some years ago, I was involved in developing a temperature controller for high-power electrical applications, and one thing I discovered quite early was why the competitors hadn’t managed to create a similar product… They struggled with heat buildup, dust burning, and unstable operation. The reason was horizontal mounting and a desire to make the enclosure as small as possible.
We did the opposite – we mounted the electronics vertically, with the cooling fins on top and the temperature sensor at the very bottom of the enclosure. The result? A deviation of only 0.2 degrees at the thermistor (temperature sensor) between 0 and 100% load. The enclosure worked like a chimney, drawing cool air in from the bottom, past the thermistor, then over the cooling fins and out the top – across a small “spoiler” that directed the airflow away from the wall, effectively eliminating dust burning as an issue. A very useful experience indeed.
Transferring this principle to the amplifiers here, I ended up choosing a so-called midi PC case, since these have exactly the properties I mentioned: extremely good airflow from the bottom straight through the case, plenty of space for the modules, and full vertical mounting. Measurements taken during testing confirmed its effectiveness.
Regardless of what people say or believe, Class D amplifiers with their accompanying SMPS units do generate heat, and there’s no point in cramming the components into a tight, closed enclosure. That can easily cause unstable operating conditions – not to mention it makes assembly, measurement, and troubleshooting a hassle.
In addition, extra heatsinks were installed on the modules – big thanks to audiom who had a few lying around – they fit perfectly!

Hello…. Not new..couple of years old but yes…Technics SUG700M2
New pic. Not much new in the man cave besides some Kanto SP9 stands and a REL Tzero sub(hidden behind the chair) for the LSX2 LT computer setup. Still thinking of a streamer upgrade from the DMP-a6 to the T8 but haven’t pulled the trigger yet since it’ll probably make me want to upgrade my dac as well.

Wish my room was big enough to try those Special 40’s. I’ve read they sound great on a Nait 50 also.

Living Room set up, LP12 inherited from my Dad. Currently comparing how my Nait 50 sounds in comparison to his NAC 202/NAP 200 system.

I’m interested how the Harbeths sound with the N50
Thanks. I’m an acoustic, folk, bluegrass listener so I’m assuming they’ll sound brilliant.
No worries, I’m sure you’ll enjoy them if you end up going for them.

I think the Nait 50 and P3ESR work really well together, especially in my medium-sized living room. The midrange sounds fantastic, and the bass is tight and clean, though it doesn’t go super deep. If you listen to a lot of bass-heavy stuff, you might want to look at something different. Overall, in my opinion the Nait 50 drives the P3ESRs really nicely, and the combo sounds great!

I’ll go along with that. I purchased my P3 ESR’s about 3 months ago and have no regrets with a Nait 50 amp. A. Great combination.

Interesting thank you. What sort of impedance are the SLOBs that they are driving?
Early days I know but what impression do you have so far of Nait 50 vs NAC 202/NAP 200?
1,6ohm in parallel mode.

The NAC 202/NAP 200 is sounding more dynamic the Nait 50 in my set up (considering the NAP 200 is in need of a service).
Definitely more firmer base and overall drives the Harbeth’s better, especially at higher volumes.
I’ve haven’t got a Hicap DR is my system, going by the forums adding one would seem to push it further ahead of the Nait 50.
That being said I love my Nait 50 and don’t think I’d be letting it go and time soon.

Out of curiosity: NAP200 … DR or not?
