Sonic frontiers

Only issue I had with a SFI preamp were the relays that were used.  They sometimes would get stuck.  Sound, though not tubey, was great.

The great thing about SF today, there is support from Partsconnexion, equipment that is over 30 years old still supported to this day.

Owned Line 3, Processor 3 and Iris CDT in mid 90's, not real tube sound, but very enjoyable.

Test the waters, you have support.

I’ve owned a number of Sonic Frontiers components over the years and the surprising negative comments some have submitted compelled me to share my personal experiences with Sonic Frontiers. 

I consistently found Sonic Frontiers to be perhaps the best sounding “Bang for the Buck” brand in home audio in their day.  Not in terms of “Entry Level gear for super cheap”, but in terms of True Audiophile sound for less than crazy insane prices. 

While I’ve never listened to the Power 3, the Power 2 is by far the BEST sounding amp I’ve ever had in my system!   For the record I’ve owned Threshold, Bryston, Audio Research, and BAT amps (among others).  At the time the Power 2 was feeding Von Schweikert VR4-SR Mk II speakers thru a Chris Johnson upgraded Sonic Frontiers Line 2 Signature +. 

I eventually sold the Power 2 because all those tubes heated up my San Antonio home in the summer.  However, I still use the Line 2 preamp in my main system.  I’ve got old stock Amperex PQ and White Globe tubes in it and in terms of sound quality, I’ll put it up against most anything else out there costing 3-times as much.  FYI - it's currently driving a Scott Frankland modified Bruce Moore & Associates D60 amp feeding Return of the Legend MkII speakers.

Sorry, I meant to say a modified Bruce Moore AUDIO amp. I was thinking back on the MFA amp Moore and Frankland designed together back in the day. Now that's an amp I wish I still had !  I used it with an Audible Illusions Modulus III to drive Thiel speakers ..... Good Times !
