New LFD Zero LE mkIV

Tell us about the upcoming base phono stage ;-)

I've just ordered the MkIV, will be (potentially) replacing my Audio Space Ref 3.1 (300B). I need to trim down the system (maybe slim down is a better description) and am taking a leap of faith with the LFD...fingers crossed I will know by early next week. Personally I don't care about the looks, so long as the sound lives up to the expectations. Shame about the phono no longer being an option though.

Received the mk4 today, just installed but no critical listening..a quick run with cd showed a very different bass sound to my audio space, and a different mid range of course, but just running in a bit with simple tv feed. The new unit is similar to the ncse, missing some beveled edges and a different LFD badge. Rear inputs close together still but present a no issue for my cabling. Though the speaker terminals are not marked and don't follow right at top per the inputs. More to come when I can compare it over some familiar songs.

Too early to say. All a bit rushed (I think also i was incorrect on the speaker posts not following the input terminal orientation and will verify today). The bass seemed a lot fuller, certainly seemed to be "cleaner", the midrange though probably a little drier than the 300B. So two points i will pay attention to when i can sit a little longer.
The sound overall though was nothing nasty - and this was fresh out of the box - and was certainly easy to tell it was not my old amp running things (better or worse i cant say yet but definitely "different").

Quick update. The speaker terminals do follow the other inputs, so my first post on this was incorrect. No big deal.
For listening i have done a little back to back against my AudioSpace. My setup is with Proac D25 speakers, both an Azur 640v2 and Denon 2930 CDP, Zu Wax speaker cables, Zu birth power on CDP, Enigma Audio power on the amp, and lastly Straightwire Rhapsody S interconnects - same as was being used previously so no changes other than the amp.
Initial impressions are good. Its indeed a very listenable sound being produced, changes i can hear are more detail in upper mids, so some recordings with clean cymbal ride or tamborines really sit in space...vocals i have not had a chance to tune in on too much just yet either.
Bass is certainly more present - a little more low bass and its cause for me to look at moving things around to counter some of the additional downside this creates. I switched back to the AS on the same track to compare, and while that also has some low end bloom it misses a little of the articulation. I'm not a seasoned audiophile so i wont try to pretend i can explain it any more than more detail across all of the "areas" that i tend to focus on.
It's not quite tube smooth, but this is fresh out of the box and may indeed be a good thing. I do however have some poor recordings i unfortunately love too much so this is going to be the real test of sitting through them and seeing whether more detail is going to make them uglier.
The unit is solid, i know there is a pic on a few places. I prefer the grey colour (i had a 3.1 with phono i ended up going to the MK4 over) and the case is quite nice. The inputs are still fairly close together but it looks very much as the back of the NCSE does. The top cover is different, maybe the side as well, but other than the different LFD emblem on the front the power and selector switches look the same as NCSE.
I will update more but so far I see this as a nice swap for my AS, its running cool, taking up less space and none of the "glassy things" i was unfortunately pressed to move on from...

I still cant convey a lot more detail on the Mk4. It's impressing me sound-wise, and I am very comfortable with the looks. The top plate is now a channeled affair, not a flat piece of metal, and overall the changes with the front panel groove and top cover at least to me look good. As much for me as the aesthetics matter but i agree i'd not want to put an ugly unit on display, but this is far from being ugly. I've seen plenty of gaudy high end amps i'd not want to have openly displayed but i would expect many people try to create a nice look for their gear where its a feature or another family member is focused on that (my move from my audiospace was exactly for that reason).
Bass is certainly an interesting topic. I may have wanted the tighter tauter bass described in the Mk3, as my speakers are ending up needing to be relocated to account for what appears to be "more" bass now with the Mk4. But back to back changes are making me question exactly what there is more of and my environment is difficult to really test correctly in - needless to say there is some subtle difference i can hear, but whether the proac's are now showing up a flaw in their bass handling or there's just a lack of synergy I need to find out.
Thanks for the additional discussion on this, it's helpful to get more information and i am looking forward to others who get the amp to provide real world experience i can learn from. The agent here also noted that this unit has pretty much the same "signature" changes I've seen announced for the North America model. I cant confirm that, and have no plan to open up and its probably far beyond anything I can detect or would notice a difference from anyway.
