Starting from Scratch -Please Help Pick 1 out of 3

Dear Friends,
Hope that all of you are well, in a moment of transitional evolutional state of mind i sold off my Rogue Cronus Integrated, my Tannoy Stirling Speakers ; well pretty much the spine of the entire system.

I wanted to start over, i listen to a lot of varied stuff ; usually very complex stuff ; i love the weight of solid state gear and the resolution of their baselines and the treble which intermittently sound "filled" ; i also love the midrange liquidity of tubes especially on vocals and the natural timbre of orchestras and drum snares.

So i had gone on a spree to audition some gears, some which couldn't be heard are also included as a part of the system (say, i listened to the power amp but not the pre) i couldn't get to some of these due to various difficulties but generally i've put a package of 4 different set ups - i hope learned pundits here can guide through this to build a good system which i will use for a long time.

I am not the type for frequent upgrades.
Thank you!

The Candidates

Group 1
------
Pre : Rennaisance Preamplifier MKIII by VAC (Valve Amplification Company)
Power : VAC Phi 200 Power Amplifiers (Valve Amplication Company)
Speakers : Harbeth SHL5 [or] Devore Fidelity The Nines (Please Pick)

Just love the look of this system!

Group 2
------
Pre : Modwright LS 100 or Ls36.5
Power : Pass Labs XA 60.5 (Class A 60 wpc) but can take a few months to save
up for Pass Labs XA100.5 (Class A 100 wpc) if it really matters.
but evidence shows otherwise :

Speakers : Magnepan 1.7
Which sounds great!

But Will the Modwright (semi-tube) impedance match with the pass'?

Group 3
-------
Pre : Leben RS28CX Premium Preamplifier
Power : CS-660P Separate Power Amplifier
Speakers : Harbeth SHL5 (or) Devore Fidelity The Nines (or) Devore Fidelity Orang Utan

Group 4
-------
Pre : Modwright LS100
Power : Pass Labs XA30.5 Monoblocks (30 watts Class A)
Speakers : Devore Fidelity Orang Utan

Also Please Feel Free to Mix-Match and Advice.

Music will be fed from my MAC to my DAC and to these.

Thank You!

I am just so worried about weak bass with tube gear, hence the confusion about using "all tube set up" but i havent heard VAC enough or lived with them - infact i've only heard their preamp, i listen to a lot of weighty stuff (but not techno or anything like that) - lots of film scores which have everything interwoven
If you are referring to deep bass extension, I'd be more concerned about the speakers than the amplifier. My impression is that the Orangutan is the only one of the speakers mentioned which will extend significantly into the bottom octave.

You might also want to consider the Daedalus Ulysses, which is rated to 28 Hz, and which several members here, myself included, have paired with VAC amplification with excellent results. It costs a few thousand dollars more than the Orangutan, but its 98 db efficiency means that you most likely wouldn't need anything near the 100W power capability of the Phi 200, and you could consider purchasing one of the older and lower powered Renaissance series 300B-based amplifiers used, at far lower cost. I'd feel certain that those amplifiers would also do fine with the Orangutan. Search posts by Audiogon member "Raquel" for lots of good info on the Renaissance amplifiers.

Best of luck, however you decide to proceed.

Theres also a possibility of a mis-matched impedance between Modwright and Pass.
That would not be a problem, at least with the LS 36.5. The LS 36.5 has transformer coupled outputs, which provide a very low output impedance and do not have the substantial output impedance rise at deep bass frequencies that is common among tube preamps having capacitively coupled outputs.

See this post by Dan Wright of Modwright.

I have no knowledge as to whether or not the same holds true for the LS 100, though.

Nevertheless, as I indicated earlier my vote is for VAC, with a suitably paired speaker that will give you the kind of bass reproduction you are looking for.
