Hello,
I'm not sure about the best portable setup, but I can tell you about some experiences I've had at a store called Audio High... see links below.
They had a setup that completely blew me away, and really opened my ears. I can honestly say I didn't know music could sound so good until I went there. (I currently have etymotic ER-4S headphones, and I thought they were pretty damn good.) I even thought it was better than their headphone setup. Anyway, here's what I can remember about their setups:
--==setup 1: analog==--
source = Acutus Chrome / SME V / Clearaudio Accurate (Turntable / Arm / Cartridge)
phono stage = Chord Electronics Symphonic Phono Preamplifier
pre amp = Chord Electronics Prima Preamplifier
amps = two Chord Electronics SPM 1400E Monoblock Amplifiers
interconnects / wires = ?
speakers = Peak Consult Empress
--==setup 2a: digital, "Chord Electronics" cd system==--
source: Blu Transport
dac: DAC64 D/A Converter
pre amp: Prima Preamplifier
amps: two SPM 1400E Monoblock Amplifiers
speakers: Peak Consult Empress
--==setup2b: digital, "McCormack" sacd / dvda system==--
source & dac?: UDP-1 Universal Player
preamp: MAP-1 Multichannel Preamplifier
amps: two Chord Electronics SPM 1400E Monoblock Amplifiers
speakers: Peak Consult Empress
--==setup3: headphone==--
source: California Labs transport (that company is no longer in business) or some Denon SACD/DVDA player.
preamp: Grace Design m902 dac/pre-amp/headphone amp
headphones: you choose... or even bring your own
My experiences:
I heard Pink Floyd's "Money" (from the "Dark Side of the Moon" album) on vinyl using setup 1, on SACD using setup 2b, and on a regular CD using setup 2a. The soundstage on vinyl was unbelievable. I knew and saw the size of the room, but the soundstage was not bounded by the walls. I've never heard anything better than that yet. I wasn't even listening to their Calix Phoenix Grand Signature loudspeaker ($67,500/pair), but those Empress loudspeakers ($28,000/pair) were impressive nonetheless. On SACD, the image came back into the confines of the room. It still sounded good, but I heard that the mastering process doesn't always work well on every sacd anyway. I don't have an SACD player so I can't tell, except for the performance on their high-end setup. The CD-player sounded just as good as the SACD in this instance. I also listened to some Tetra ($1.5k/pair) and Epos ($0.3k/pair) speakers that sounded quite good for their price.
I told the salesperson I don't even want to know the prices of anything else after he told me that the Empress loudspeakers are $28k/pair, cause then I'll cry, but... If you're curious, here's my guesses! (You'll really have to ask someone more knowledgable for these prices)
I think the McCormack setup (universal player -> pre-amp) is around $6k to $8k
I think the
Chord Electronics setup is at least $8k and more likely $13k.
I think the turntable/arm/cartridge is $15k all together.
I have no idea how much the interconnects or speaker cables cost, but I remember that the speaker cables were about 1.25" in diameter. (I have a 500W monoblock in my car, and I don't have wires that thick!)
Anyway, the guy there (Eugene I think) is really cool. His philosophy seems to be to just let you hear really good music, and your ears will tell you what you need to know. So if money isn't an issue, I'd head there for some TRULY EXCELLENT service! And you can try the AKG-1000
, HD-650
, HD-595, HD-580 (some BeyerDynamic, etc) headphones there on setup 3.

PS - I went to Magnolia A/V to demo their "High-End" room, and I wasn't impressed (especially after visiting Audio High). They must have done something wrong, because I was getting some weird bass cancellation in their room, despite sitting in the "sweet spot chair". They had some $4.5k Martin Logan electrostats. At least the imaging was good. It had near ER-4S definition in the midrange and highs, and a HD-600 bass & midbass. A nice combination, but inappropriate setup.
