Amp / Speaker setup for streaming and vinyl

Peachtree was WAYYY ahead of the times with the Nova & an all in one solution is,IMO,the ONLY way to go these days.The problem though is I never cared for the combination of Digital Class D amplification & the SABRE DAC's they use in the current production.They just don't have that lucid MOSFET/Tube tone of the original Nova.Too bad prices are WAYYY to high for a decent condition unit.
 In your budget range my $ would go for a Quad Audio UK "Vena 2"..Fully loaded,you can Stream via USB & Toslink or Bluetooth & it also has a Moving Magnate Phono Stage built in.It will be wonderfully musical with a natural tone & bring out the best the 602 speakers offer without highlighting the slightly brite/harsh tweeter...When you save again to upgrade speakers get yourself a pair of Heco "Aurora 700"3 way floorstanding speakers for about $1200.00 delivered.They would THRIVE on the Quad amp..

   I was running a Nova 500 with Paradigm S2s and a Servo 15 V2.  I also had a Technics SL-1500 turntable.  To stream I used my iPhone connected with the USB/Lightening cable.  It sounded really good.  I tried some Magnepan 1.7i and they did not sound so good.  I now have Harbeths and they sound great. 

I’m not familiar with the Quad but it seems to have all the features I need. Price looks fine for me. Based on a quick review, might be a little tricky to get in the US though. 

Quad:Been around a LONG time & HIGHLY regarded.Several online AD's in the USA.
If you want a HUGE taste of the absolute best for about $1600.00 there is the iFi Audio "Retro Stereo 50"TUBE integrated amplifier/DAC/Headphone/Phono,also available online.Doesn't have huge power but speakers like the Heco are 93db.sensitive & don't need huge power.
 Another thing you could do now to the 602's that won't cost much is get a decent pair of speaker jumpers & get rid of those metal bars that join the 2 sections of the crossover..

I'm not seeing much in terms of used Vena's out there. I'm sure this as been covered elsewhere, but what are some recommended sites to check (besides this one, of course).

Also, any thoughts on the Audioabs 6000a for my needs. Pushes the budget a little, but seems to have the right features and is well reviewed. I can't tell if the newer "Play" version adds any real value over running the streams through the Airport Express.

Thanks for the help.

Listen,on USAUDIOMART.com RIGHT NOW there is a Cayin "CS55A" BRAND NEW IN BOX with KT88 tubes.It has built in DAC with USB(only)input,a Moving Magnate phono stage & a wonderful,tube driven headphone out.
Price is $1300.00 + shipping.BUY IT!!!
 NOTHING & I MEAN NOTHING can even come close to the performance of this amp for the $ & EASILY competes with all in one solutions that cost $3000.00+!
 You can even change the tubes from KT88(which I prefer)to EL34 with flip of a switch.Biasing new power tubes is EASY with built in bias meter & top plate mounted biasing pots.
 I owned this exact amp & it took a VERY expensive KT150 amp to upgrade.
YOU WILL NOT REGRET buying this amp.

Interesting. Will check it out. Any idea how I use the USB input with the airport express? I can just connect via analog RCA, but if I understand correctly, I'd be bypassing the Cayin DAC in favor of the Airport, which seems sub-optimal.
