To Whom it May Concern: Though I TOO am more than somewhat skeptical regarding electronic/audio component "break-in", (driver/driver-surrounds MECHANICAL break-in notwithstanding...(and yes, I DO understand that expectation bias sometimes DOES rear its "subjective" head... ;-) ...))...

Dear bigshot: Thank you for your prompt response!... Here is my current situation...and set-up/signal path... Signal Sources: Streaming audio output via laptop PC..., Dedicated CD transport, (new)...(Cambridge Audio CXC)... BOTH feeding a Schiit Audio...

Dear bigshot: Did not realize you had responded so quickly...my thread response alert function must not have been working... Yes, I understand that by its very definition that a DSP will indeed alter the sound of the system... :-) ...and YES, you are correct with regard to my system...

I purchased my Freya within about a year(?) of it first becoming available ...so, it was probably their first iteration...and yes, the tube/balanced mode did/does exhibit significantly greater gain than the passive and JFET modes...(which are for all intents and purposes equal in gain...perhaps...

To Whomever Would Like to Assist: In advance, I would like to extend my sincere appreciation to those who are willing to assist, and I apologize for my loquaciousness... ...and I certainly hope this is the most appropriate forum in which to post this inquiry... An OLD audiophile here...

Dear Pietro Cozzi Tinin: Thank you for your prompt and clear response to my inquiry! I have been attempting to do effective research regarding this question, and glad you can confirm, via actual experience, that which at least one other has suggested, (that the Circlotron amplifier...

For the last couple/three days, I, as well as Justin at REL have been attempting to contact Schiit Audio regarding compatibility/connection issues between the Ragnarok and REL subwoofers...TYPICALLY, Schiit Audio is relatively prompt regarding responding to e-mail inquiries...however, neither...

Dear jcn3: I very much appreciate your prompt response/input, and genuinely hope that there are no little known "quirks" to the "Circlotron" amplifier design/topology/Ranarok that would conflict with your suggestions. I am also hoping to hear from someone from Schiit Audio, be it Jason or...

Ragnarok Connection to REL Subwoofer Compatibility Inquiry... I do not mean to derail any current threads/topics...and am genuinely sorry if this question is off current topic, HOWEVER... I need to know if the Ragnarok amplifier section/speaker outputs can safely be connected via the REL...

Though I AM aware that this "Schiit Freya Impressions and Tube Rolling Thread" has evolved primarily toward the "Tube Rolling" end of things...AND, as such...the Octal LISST's developed/manufactured for the Freya are NOT "Tubes" per se...HOWEVER, I would still love to hear the impressions from...

I guess I was a fortune one...my LISST's seem to be OK...though when I thought to remove one right after installing it, it came out without the alignment/center post, so, I guess it is LISST's forever...lol... I concur that relative to the new production Tung Sol's I was using, the LISST's are...

The LISST's get warm/hot to the touch, but certainly no where near the "skin-blistering/frying(?)" temperature of the glass tubes...I did not attempt to measure the temperatures generated by either tube type however...

No problem Ghosthouse: As I had a bit of a challenge finding the location of the Octal LISST's on the site, for anyone who is unclear as to where to look, "Tom E" very promptly responded to my e-mail inquiry with: " Tom E (Schiit Audio) Feb 5, 10:08 PST Hello, Please visit...

This just noted, on the Shiit Audio website, PRODUCTS : PREAMPS & CONTROLS : Freya: Tubes: Octal LISST (Solid State) and within the "News" section of the site...("Octal LISST, New Tube Options | 02/5/18") "Octal LISST, New Tube Options Solid-State Tubes Now Available for Saga and Freya...

Dear hornytoad: Thank you!...I am glad that you have established sufficient rapport/trust with them that someone there provided that specific and clear information to you...though I certainly understand their company policy, and reticence to offering such information to the general public...

I keep checking within the Schiit Audio website to find a listing as to availability and price of the LISST's for the Freya valves, that one or more fellow HeadFier's had assuredly stated that Schiit Audio was attempting to provide by the end of the 4th quarter of 2017... I have not yet seen...

[ " Hi Namaste - I don't want to divert this Freya-dedicated thread to a cable discussion and incur the ire of the moderators so I will try to be brief. I have found Freya sensitive (a good thing) to interconnect changes...more so than with the tubes I have tried. If you are in the US, get in...

Dear Ghosthouse: Thank you for such a clearly expressed, detailed and complete response to my query! I appreciate your neutral/objective analysis, as well as providing "audio system" context with regard to the application of said IC's and speaker cables. Indeed, "The Cable Company" is...

Dear Ghosthouse: I noticed your post on wire...and having recently purchased a pair of Audience Audio, Clairaudient 1+1 V2+ speakers to use in a "secondary" sound system, I am hoping to obtain your experience regarding Cardas wire in general and Cardas Parsec wire in particular... I am...

Speaking of resonance control related to tube use and so forth... I was hoping to completely circumvent THAT issue, (among others), by purchasing a quad of those LISST's for Freya/(6SN7 equivalent, Linear, Integrated, Solid-State Tubes), that at least a couple of Head-Fi'ers have reported in...

Dear Nuttinbutair: Yes, I of course agree with your agreement of my "#1" reason...lol...and Yes, I agree that the H.T.F., (or lack thereof with headphone listening, unless the headphone amp. generates/implements a well designed H.T.,R. in the headphone signal path), impacts our perception...

Dear Nuttinbutair: I too tend to hear more significant sound stage/imaging differences while listening to a loudspeaker based system than through headphones, (when trying different settings, i.e. passive/active/different tubes, etc.), even when both systems/component chains are of reasonably...

Dear Ghosthouse: When I switch between solid-state/JFET and tube mode, (new production Tung Sols in the gain stage, stock Russian tubes in the buffer stage), I hear minimal/subtle frequency shift, however, I DO hear an appreciable increase in image presentation breadth and depth...
