O-Noorus D1 - TPA3255 PFFB Stereo Amplifier - Front Display, Tone Control (with bypass) and Remote

[Guddu]

I suppose I must not exist then. https://www.audiosciencereview.com/...d-measurements-of-hifiberry-dac-pro-xlr.8569/ for £60 is the first that springs to mind. I spent a bit more (but still 2 figures) on used interfaces, and would certainly look at amps in the same ballpark, although I probably have too many already.

Interesting, I do hear you but I can easily find a cheap better single ended output DAC (better in terms of measurement) than this balanced DAC if I have to. But its just me.

Yeah, like SMSL SU-1

Yeah, like SMSL SU-1

+1, so it's just not me after all!

The thing with frills, bells & whistles is that many just desire and wish for those even if needed or not.



Its all about the used case, a DAC without remote like SMSL PS100 that has HDMI ARC, SPDIF & USB inputs can get benefit out of it.
Some may care, many won't.

its more to my point that adding these things always incurrs a cost

i notice the competition sometimes does not offer these things.. if you want a more traditional 'power amp' then you can go down the route where you dont even need a vol. ctrl.

i give a lot of credit to companies who add the extra features that does cost money to include but then keep the price at $100

Any links, searching on aliexpress gives me nothing. Gonna build a first stereo for nephew based on this..

Search results are region limited. If the vendor doesn't ship to your country, you will not see it in the search results.

Lots of people liked smsl a300 amp, if this plays without the hiss in the treble then it's enough for most consumers..

I really don't get it. If amp has hiss, it is no good for anyone...

It does depend on circumstances. What is intolerable hiss for someone with sensitive speakers listening nearfield may be completely inaudible to someone else using less sensitive and more distant speakers.

Most won't hear as it as the amp is used at a distance. It also depends on the display strength used..lowest setting gave least hiss

 

[YesChickenNuggets]

Yeah, like SMSL SU-1

Exactly,

I also do not want xlr. 100+ sinad on RCA. I don't even want to spend the extra $2 on xlr cables. Over the years the audiophile hobby has gone in a stupid direction, vanity driven, vapid, broken.

If it wasn't for Amir holding the scammers accountable, the community could only have gotten more idiotic.

Thank god for ASR.

There's really no reason for the vast majority of the products today to exist. Given time, we'll have SU-1 dacs bolted to something like the TPA3255 w/ pffb, and that will be the default device people buy. Unless the big $$ amps can put up some BIG Sinad numbers, they're not truly useful. 10 watt is more than most people need, and 3255 can already do 250 in the v3mono.

there's people behind the scenes planning what's coming up next and what you describe isnt far off

i find it kind of curious how things have panned out so far

the A70 has had teething problems and price is kind creeping up to ~$200... to me is there $200 worth of 'innovation' there?

and makes it harder to justify when the V3 mono system is around $250... if you're going to get in to this hobby then $50 isnt a big deal

so there still upcoming stereo products from fosi to come

BUT as you say, you dont need to even spend $200 to get comparable quality

If this company can get it done, for less they why bother? this is from someone who loves spending money on big class a/b amps

and so i'm waiting to see what this D1 is like and I expect they will follow up the D3 with a PFFB product with updated DAC and BT stages

I am running the D3 on a set of speakers right now that are $1,000 and it really is more than good enough

even for older folks like me who was around when there was only tapes and vinyl, there's still new innovations coming

ALSO my SMSL C100 on the D3 is a real good combo

Why do you need a C100 when you have a D3?

 

[Guddu]

I guess he meant D1, probably.

An external dac might be better. I use a SU 1 for Toppings mx3s

 

[Guddu]

If using an external DAC then D1 is a better choice between D3 & D1. They both are around same price point.

 

[TonyJZX]

the dac stage on the d3 is passable but i dont think its as good as the c100 (but its $100 dac on $120 amp)

i have a few dacs obviously for testing etc.

the drawcard of the D1 is the pffb.. the D3 does not

ALSO in this category its nice to have discrete components so you can chop n change as you wish.... eg. the D3 does not have DSD or MQA if you want these things

nor do any of these have headphone support, some of you guys like that

I bought the D1 not for myself though, it's going to nephew. He's getting my Topping D10s

Why does RCA incur a sinad penalty, shouldn't it be possible to get the same sinad over rca as xlr?

Coming to this conclusion as well. There's only so much snake oil that can continue to exist outside of the realm of objective measurements like SINAD.

Really good, affordable powered speakers might be the next field to take off now that these excellent audio technologies are so cheap.

Imagine something like Elac Reference DBR62 with built in multiple-input SU-1 level DAC and PFFB class-D amplification built in, for $700 shipped, or same built-in dac/pffb amp stack in the Sony SSCS5s for $250 shipped. Audiophilia for the masses.

A lot of new people are going to be blown away at the difference from their sound bars and cheap PC speakers.

Diversity and availability provide options to a buyer, one must have choices available in today’s market.
*** Sticking to the subjected product- O-Noorus D1 for the discussion is required, please. ***

I have just got the O-Noorus D1 amplifier yesterday, and I am transitioning my setup from Fosi v3 mono (PFFB) to O-Noorus D1 (PFFB) as I am writing this and the first impression is totally positive for me.
It seems clean and quite powerful, in general.
I am looking forward to proper testing on all operational features on this.

 

[TonyJZX]

i'm seriously questioning whether pffb at this level with most common sensitivitely and load speakers is going to make that much of a difference

however i think it'll come to a point where pffb can be added for very little cost so why not have it

also, we need some testing at the 48v 5a level
