Should I: Bi-Amp or upgrade my Phono Preamp...?
Yesterday at 23:29:21
 
Hello fellow fanatics of sublime music alchemy,

I have a conundrum. What to do with my decware amp reservation?

Background:

I currently have a lovely system. The digital stream starts with a Nagra Streamer —> Soulnote D1 DAC —> Decware ZBit —> ZRock —> Decware Zen Sarah 300B —> Pure Audio Project Duet 15 Horns.

Its lovely. I have spent a lot of care tuning my digital chain and power delivery.

My analogue chain consists of: Audio Technica 160-ML Cartridge —> Music Hall MMF-9 Turntable —> McIntosh MP-100 Phono Preamp —> (and soon) XLR to Decware ZBit —> Zrock —> Decware 300B —> Pure Audio Project Duet 15 Horns…

QUESTION FOR YOU ALL: What should I do with my Decware Amp Reservation?
(I have an amp reservation ticking away at decware, originally for a 300B but I lost patience and picked one up used)

Should I:
1. Get a Zen SE84UFO25: And Bi-Amp my Pure Audio Project Horns?
   1. IF SO: How best to split my signal from my ZRock to the two amps?
2. Get a ZP3 Decware Phono Preamplifier: My McIntosh phono preamp sounds… polite and tame… boring. If a proper phono preamp really unlocks my analogue…. Shouldn’t I? I listen to primarily streaming through qubuz + Roon, but I do love a vinyl session… and am always reaching for the stars in my lovely main system….
   1. I see that the ZP3 does not have XLR inputs. How best to integrate a ZP3 into my ZBit —> ZRock —> Sarah chain? Or should it simply feed straight from the ZP3 to the second RCA Input on my Sarah 300B Amp? What is the best way?
   2. Or, if the phono preamp —> ZBit —> ZRock is the best chain for my analogue, which phono preamp do you all suggest?

THANK YOU!!!!!!
Ahhhh such lovely options to swish around my eardrums…

If you do decide on either of the options that would necessitate a switching unit I recommend considering a Goldpoint unit. I use one to switch between my XLR DAC output and my XLR output from my phono preamp into my ZBIT and notice zero sonic degradation, couldn't be happier.

If you are bored with your phono output from the McIntosh. . . consider the ZP3. You'll find an exciting tube complement.

Richard, I love your enthusiasm – it’s infectious!

My knee jerk reaction to your post was as follows:

A what does bi-amping have to do with anything— seemed like a red herring given the focus was on the analog end

B wondering why you’re focusing on the phono vs upgrading your turntable and arm and cartridge since it’s not equivalent in caliber to your digital source components.

However, since I still consider myself somewhat of a rookie on the analog side of things, I wanted to confirm my assumption.

So I decided to ask Claude and I am pasting it’s response below

Your instinct is right, and it’s a pretty clear-cut case once you look at the actual weak links in his chain.
His digital chain (Nagra Streamer → Soulnote D1 → ZBit → ZRock → Sarah 300B → Duet 15) is high-effort, high-cost gear at every stage. There’s no obvious bottleneck.
His analog chain has a real mismatch. The Music Hall MMF-9 is a solid mid-tier belt-drive table (roughly $1,500–2,000 class) — a fine table, but nowhere near the resolving power of his digital front end or his amp/speaker back end. The AT-VM95ML-equivalent (assuming he means the AT-VM540ML or similar 160-series) is a good moving-magnet cartridge, but again, entry-to-mid-level relative to the rest of the system. So he’s asking whether a phono stage upgrade (McIntosh MP-100 → Decware ZP3) will “unlock” the analog side.
It won’t, not by much. Signal chain logic: you can’t recover resolution the front end never captured. A phono preamp upgrade will change tonal character — the ZP3 may sound less “polite,” more textured — but it’s working with whatever the cartridge/table/arm already extracted from the groove. If the turntable and cartridge are the resolution ceiling, a better phono stage just gives you a clearer window onto a blurry picture.
His question 2 (ZP3 vs. better phono stage generally) is actually the less impactful of his two choices. His question 1 (bi-amping with a second SE84UFO25) is a system-design question, but it’s arguably premature too — bi-amping a horn-loaded full-range-ish speaker rarely fixes a source-quality mismatch.
Given his stated priorities (“reaching for the stars,” loves vinyl sessions, wants parity with the digital side), the money would go further as:
     1.      Turntable/tonearm/cartridge upgrade first — this is where the actual information gets extracted from the record. A better arm and cartridge (or a full table upgrade) raises the ceiling for everything downstream.
     2.      Phono stage second — once the front end deserves it, the ZP3 or similar becomes worth optimizing for.
     3.      Bi-amping — a system-voicing decision, separate from either signal-quality question, worth revisiting after 1 and 2.
He’s essentially asking “should I repaint the room or reinforce the foundation” — and picking the phono stage first is repainting
