Lush analog sounding class D with silky top end, a marriage between Philps CD players of the 80ties with the Highend'ish Hybrid Class D power amp Fosi V3 ,  preceded by the Fosi Tube pre-amp P3 from 2023.

On top one of the early 100 type, the Philips CD150 cd player with a four fold oversampling 14 bit DA converter with digital filtering,  the TDA1540 DAC from 1983 and still in great working order

(The TDA1540 DAC was superseded by the TDA1541 Philips  first true 16 bit DAC still using the four fold oversampling and digital filtering )

Below the CD150 , the Philips CD player CD471 from 1987 with the even better TDA1541 DAC the TDA1541A R1

These classic 80ties High-end cd players analog output  is amplified by Fosi P3 tube pre-amp with JAN General Electric 5654W tubes rounder and Fosi V3 Class D power amp with the Excellent Texas Instruments TPA3255 power chip from 2023, a happy lush sounding marriage !!!! 

The Fosi's  are both next to each other on the lower tray of the table,  and hardly use any space since the both have a footprint of 10 x 15 x 5 cm (W, D, H)

Note: The Fosi V3 can be used alone (without the pre-amp) with the standard delivered 32V 5A power supply (160watts) , or with an 48V 5A (240watts) power supply which costs around 50,- extra.

It all depends if you use 4 or 8 Ohms speakers , see review below. I have both just in case.

The Fosi tube pre-amp P3 has besides volume pot,  treble and bass +/- 6db pots , and as a bonus blue tooth.

I have the Fosi P3 preamp, but i don't use the tone-control (both in neutral), or blue tooth  , i have the volume pot standard between 12 and 3 o'clock on the pre-amp, for the gain of the tube sound, the rest of the volume needed i use the Fosi V3

Logaritmic  potentiometer

So basically i only use the on/of switch for the tube gain, and the rest i do with the pot meter of the Fosi V3.

For details see Fosi audio V3 and Fosi audio P3 on amazon.

Independent Review Fosi V3 by Audio science review :

A british audiofile on Fosi V3 review

Amplifier ABA awards 2023,:

Muses02 op-amps.

After intensive listening the only thing i swapped are the older type of Texas Instruments NE5532 op-amps chips (operational Amplifier) for the more lush sounding Muses02 from the New Japan Radio Co. Ltd ,for its very nice wide and deep soundstage.

"The MUSES02 is a dual bipolar input high quality audio operational amplifier, which is optimized for high-end audio and
professional audio applications with advanced circuitry and layout, unique material and assembled technology by
skilled-craftwork. It is the best for audio pre-amplifiers, active filters, and line amplifiers with excellent sound"
