Given our intimate knowledge of these product lines, pcX is proud to make available state-of-the-art updates and modifications to these classic SFI, ANTHEM and ASSMEBLAGE products. These go well beyond the Signature, Special Edition or Platinum Series updates originally offered by SFI and TPC (all of which were originally defined, specified and voiced by acX/pcX’s president, Chris Johnson) we call them our SE+ upgrades. We now have a palate of parts available to us, that SFI did not... thus, we can achieve more with each mod. Moreover, as we don't sell these mods through dealers, they are generally 1/3 to 1/2 below the cost SFI previously charged.

We have pre-defined mod prices on most every SFI, ANTHEM and ASSEMBLAGE piece, but can customize those substantially, according to your sonic tastes and budget. Moreover, we can perform a substantial (but not all I'm afraid) amount of repair work on this gear too... our repair rates are a very reasonable $74.95 USD / $89.95 CAD per hour.

The work is performed by previous SFI technical and design staff -- either Glen Dolick or Vince Siu.

I have had the Sonic Frontiers SFS-80 amp then upgraded to the Power-2 and Line-2.  Purchased new long ago and still going strong in my 2nd system.  I turned to SET amps and horns a few years ago in my main.  As someone mentioned Chris is still in the audio world running Parts-Xpress and I understand that he does repairs and upgrades though my setup has been perfect for the last 26ish years.  Buy with confidence as the SF stuff was always known as being built like a truck.

I recently had my SFL-1 and SFD processor upgraded by The Parts Connexion. They run a very efficient upgrade process. You can speak with their staff about what you want done and how much you want to spend. They help with the shipping and paperwork to get your stuff to Ontario, Canada and back.

Highly recommended.

If anyone found a Sonic frontier muffled sounding there was something wrong with a tube most likely or the amp it self. The sonic frontier amps and preamps were very good at tonal balance and resolution. Perhaps a tad slow huge sound stage. Don't be afraid to upgrade the tubes in the cd seperates they se to like the reflector 6922 equivalent. That is worth an ask to Chris Johnson stock they used sovtecs mainly tonal balanced always seemed good to me but many other choices I prefer. I have dealt with audio connection/ parts connection for a number of years that is a straight up kind of place very professional and things have always happened the way they said they would. The fact that it is a little older wouldn't bother me in the least well built and has more life left in it than a bunch of new stuff being sold today. That pair you should be able to buy for about 10000 Canadian or 7500 USD. In fact there are ads on Canuck audio Mart for each piece at the moment. Two different sellers one with the pre the other with the amps. The power three amp has boats loads of power it will be hard to find a speaker that those monoblocks cannot drive. I have the DAC and transport three as well as a anthem six disc changer. The DAC and transport three are at the pinnacle of redbook cd players. One of the five best ever made. Enjoy your purchase I am sure you will. I hope you understand to hear that power pre at it best you are going to need top tier everything else to go with it including wire.

I have a Sonic Frontiers SFS40 power amp that I use with a Conrad Johnson PV5 in a secondary system. The SF amp produces an excellent soundstage with lots of low level detail and air around classical and jazz music. Perhaps those complaining about the Sonic Frontier amplifiers had some type of problem which can happen to any gear?
