Hi,

Has anybody tried one of Connexelectronics Balanced Input Phase Shifter boards
with these tk2050 modules?

Would it improve sound quality?
I Presume you still would be unable to bridge though as they are already full bridge?

Also as for your new T3 module. I am interested in this board also!
You say that you are thinking of building a linear power supply with speaker protection and anti Pop system. I would only consider using SMPS or batteries so for people like me could you make the speaker protection and anti pop board as a separate item?

Kind Regards

Hi, we can unsoder PSU parts and just use other functions on board. Or sometimes tank caps can be used too if like.

The B.I.P.S. on tk2050 would be unuseful.
According to Christi (the Connexelectronics owner) the B.I.P.S. is useful on the TA3020 only if used as a subwoofer... (he emailed that to me), so considering the low current absorption of the TK2050 you don't need the BIPS.
Just use a powerful enough power supply.

The Hifimediy V1 board with the Alps pot is sounding absolutly sensational here, straight outta the dac , 30.5volts in , i have one V1 powering the mid/hi section of my Von Schweikert VR4.5s, superb sound at any price and for the money its simply unbelievable . its even bettter than the V2 was. and the heatsink on the V1 barely gets warm.and the coils stay cool as.
i now have the V2 board on the bass section (4x Eton 8inch woofers) it has a very good grip on them and goes waay deep down there. The heatsink and coils on this amp do get quite warm esp after an hour or so at higher volumes :-) but it does it very well :-) still ,i would like to hear the new 300watt T3s on the bass when they do come out ;-)

These amp boards reveal the sonic differances between differnt sources VERY clearly!

Good to see the new tweeked design V2 has the larger coils same as the V1!

great stuff keep it up !!

Today i installed 2 of the V2 amp boards in an Alpine based car system - the V2 sound superb of course and LOTS of Grunt . :-)

To power the two V2s boards in the the car i used a 13amp version of this 27.6v power supply ,(you have to email to get the 13 amp version) but anyway im sure these 5 amp supplies shown are fine for one V2 : Autocostruire il negozio degli autocostruttori
