Hello Ked, and all; I've been following much of the Lampi related threads here for awhile and wanted to chime in again with a few of my own recent experiences. After your visit here Ked, I could not get the sound of those KR 242's out of my mind. When I had first told you my Big 7 was equipped with an EML Mesh 5u4G and a pair of Sophia 300B Carbons you said you would bring your own DHT's [the 242's] when you visited. With the 242's installed my system was 'Gushing' with vibrancy, dynamics, bass extension I've never known, and a soundstage with such presence I remember we were both looking at each other in almost stunned disbelief.
Well it has taken me a while, and I have added a few noteworthy tweaks in the interim *, but I finally purchased my very own pair of brand new KR 242's [thank you Lukasz!].
And they ARE Stunning! I'll say it again: Stunning.
I read everyone's opinions and experiences with the PX4 and PX25 and I was truly tempted to choose either of them but that memory of that day just couldn't be shaken. I checked with Lukasz and asked his thoughts on it. I told him what I remembered from that [barely 3-4 hour listening session] and how we were both so blown away... and he reminded me how personal opinions and experiences may abound but if hearing it in one's own system can truly prove a unique synergy... then there is NO better deciding factor...and so "I knew what I must do". As of this writing they've been ON for 26 hours...My listening was done with barely 2 hours' warm-up.
I'm giving them another day or two then 'going back in' [to the listening room!] and will undoubtedly be pinching myself again in disbelief.
FYI over these past few months the added noteworthy tweaks* have included an upgrade to the Apprentice Series of Sistrum platforms (I had the earlier model of it) for both my B7 and my TRL Dude pre-amp; a Synergistic Research Black series fuse for the B7; a "split" USB cable (power in one leg/signal in the other) made by my good friend "Triode Pete" at Triode Wire Labs; a 16" ASC Full round Tube Trap (in addition to the 2 @ 11" already there); and last but certainly not least my new Lampi Komputer feeding the B7 with lots of well recorded music selections....
So, I'll leave it on this note...system synergy...No matter what you've got, experiment, listen, try some more... and enjoy the journey.
