Just before the unit went to pcX I was running the JJ E88CC/6922 gold pin which offer a relatively high dose of tube attributes. Of interest maybe is some tube rolling that I did, ( see thread on another forum). While the Line 1 is in the shop, I'm driving my power amp directly from my Topping D90 DAC the sound is quite tolerable but not the same. I dropped it on in person to Parts ConneXion because its only a 1.5 hour drive from my home - safer and quicker than shipping.

One way to look at is is, Which high-quality, full function (except phone), fully balanced & differential preamps can one buy for $2100, even used? Not many. This work will probably cost me the equivalent of about US$1200.Ĭonsidering I paid US$900 for the preamp, one may consider whether the upgrades are worth it.

My SF Line 1 is into Parts ConneXion for the "SE+" upgrade as well as the Volume control repair and chip upgrade. I'm hoping the the SF Line will preserve more of the inherent transparency than the Freya + - the Line 1 doesn't have a Passive Mode However I also fined that with certain types of music - in particular large-scale orchestra - I loose too much transparency, consequently I end up listening using the Freya +'s Passive Mode, (in my case that doesn't loose any dynamics). I have tried my current Schiit Freya + in Tube Mode which produces tube effects of a mild sort. By the contrast the Purifi is super transparent and resolved and also hyper-dynamic but lacking in warmth. The Monarchys were a high-bias class A type, fairly transparent but a also a bit mellow in presentation. But today I's driving a VTV Audio Purifi stereo amp. I liked back in the day but that was with different associated equipment most of the time I owned it, I was using a pair of Monarchy SM70 Pro's. the Line 1 is whether I will like it today. granted, partly for reason of nostalgia.My concerned re. The first bought in 2009 and sold in 2011. More later on those mystery tubes after I get a translator involved. Anyhow, in addition to advice on a fresh set, any advice on the tubes I do have would also be greatly appreciated. I’m also assuming zero hours on any of them. They are all in their original packages (3) unopened, (1) open, probably for inspection. The manufacturer appears to be Russian but as I do not read Russian, I just don’t know. Additionally, I have (4) mystery i/o tubes. I also have a matched pair of Sovtek 6922’s. I have (2) of the original (4) Gold Aero 6DJ8’s. I also have matched pairs of Svetlana E元4’s, they appear to be Svetlana’s “Mullard” copies. I have the original matched pairs of Gold Aero E元4’s. I have no idea how many hours are on any of these tubes. The amplifier did come with (2) complete tube complements. I am open to either tube complements based on the stock E元4/6DJ8 setup, or any of the optional tube complements. I am looking for advice on good “new” or “new old stock” tube complements fitting within a $300 budget. It will probably be powering a pair of B&W 805’s, but I need to break in this amp and engage in some in-home listening room demo sessions before any final decisions. I recently acquired a Sonic Frontiers SFS 40.
