Hello everybody – my first post!

I’m tentatively venturing into the audiophile rabbit hole starting with reviving some old gear and tweaking/adding or upgrading until they give up on me

Limitations are: space (read clutter headroom -until I move) and budget (<£1k until I have more experience)

My current set-up is therefore very simple:
Hifiman 601 —> B&O Beolab3

I’ve always liked the bias to warmer musical sound the 601 gives, so I’d like to continue in this direction and go next level by putting tube hardware into the mix. Variations I’ve researched are:

1) Tube pre-amp (rather than full amp which would be too much for the Beolabs’ inbuilt amps right?)

601 —> pre-amp (integrated for volume control?) —> B3
Eg: Icon Audio LA4 MkIII Valve Pre Amplifier (c.£2,000)

I'm realising this is more of an aspirational option as even this entry level example exceeds my current budget - but is a buffer version (sub-£1k) worth considering?
...or what about “too cheap to be true” offerings like this:
https://www.amazon.co.uk/Fosi-Audio-P3-Headphone-Preamplifier-Black/dp/B0CJBKWF43

2) Desktop DAP w/tubes

DAP —> B3
Eg: Astell&Kern Acro CA1000T (c.£1,800)

I was considering this when I saw a price drop to £999…so maybe worth investing some patience and waiting some months to see if this is realistic, especially if a newer model is launched? How long-term would its software and OS be supported is also a question..

3) Portable DAP w/tubes

DAP —> B3
Eg: Cayin N3 Ultra (c.£450)

This last option is the most simple (cost wise too!) - would sound quality difference be very noticeable from those above? It would mean a redundant/retired 601, and although a definite upgrade, not sure it would be as future durable due to reliance on an OS (though same could be said of the A&K)

Additional info:
Unplugged from speakers I’ll typically use the 601 with the now almost as venerable RE2000 IEMs (bought recently at the knocked down price), or classic Grado sr60x (with DIY washing-up sponge ear pads 🤣)…

Thanks y’all (be kind!)

You would have to figure out if you can preamp active speakers using the vali 3 with it's RCA outs. If you had passive speakers then it would be as simple as: Source->DAC->Preamp->Amp->Passive Speakers.
But I'm not sure how you would achieve that with active speakers since I don't know of a cable that you use to go from RCA to whatever inputs your speakers take. But if you were to find such cable the chain would be something like this:
Source->Preamp->Active Speakers

Actually I was thinking I’d use the V3’s headphone out to connect to the speakers (as I currently do using my DAP with a 3.5mm jack adapter to speakers). But because they’re active speakers wasn’t sure if the V3 would blow them! If using the rca out is safer then I’d use this: https://www.amazon.co.uk/kenable-3-5mm-Stereo-Socket-Adapter-Black/dp/B003OSPTVU
I’ll ask the UK retailer, they have the Vali 3 in stock..
Either way, it would be in essence be as your last suggestion - thanks

Yep, rca to speakers way to go…veering towards xDuoo TA-26 now
