Tpa3255 or Irs2092 - My first amplifier
Hi all,
It's one of my first posts here but I spend a lot of time to read your valuable forum. I am a beginner in electronic so please don't be too much rude with me... ;-)
I want build my first amplifier during this period of quarantine, to try to learn something and spend my time a little bit better.
I have a lot of concern about it, but the first, is which type of board I have to pick. The 2 main options are tpa3255 or Irs2092.
The tpa3255 seems that the best one is the one provided by 3e audio.
For Irs2092 I have some options. The first 2, is an already build and tested boards:
Sure Electronics 2x125w
WONDOM | STORE
LJM L15D-power (It is good because have integrated already speaker protection and rectifier.

The second option (and it is my preferred) is buy a DIY kit, to build manually my amp with the solder.
LJM L15D-PRO is the only available kit that I found, and I don't know if it is LJM original one, with a good set components (And the rectify part is missing, only the speaker protection circuit is available)

In theory my target is build an integrated amplifier with a preamp and a DAC included.
My objective is that the quality of sound must be best of possible (HIFI?) and have a really quite output in idle without hiss, pop, or ommm noises. (I own a DENON 3500, and could be nice if my selfmade amp could be better that this)
The preamplifier that I have in mind to build and use with the above boards is this one:
Mezmerize B1 Buffer – diyAudio Store
What do you think about it?
Could you help me? (@ljm_ljm)
Thank you a lot.

I have the LJM L25D, running on a +/-55V SMPS for about 4 years. Works very well, quiet and can use a 50k or 100k pot, no need for a pre-amp for me.
Alternately - also use a TA2020 4-channel amp quite a bit, for Sure - AA-AB009 model #. It is only 30-40w but useses an old laptop brick of 19-24V and has all protection built in.
I would buy a pre-built class D amp - or go fo a Class AB if you want to learn to solder. Class AB is much easier for a first build and soldering.

Thank you for your suggestion, but I need a preamp, because I need to have several input (for a DAC or a streaming board).
I want as well use this amp in conjunction with my AVR.
In Terms of audio quality si better tpa3255 or irs2092?
