Dream Speakers = landed. Now I need to feed them!


So I scored a pair of Belle Klipsch (1987 models, AB crossover).  I would have gone for Khorns, but the room they were going in just wasn't going to work.  RIght now, I'm running a cheap little Sony (STR-DH190) stereo receiver on them, and even that sounds amazing, but I know I've barely scratched the surface of what they're capable of.  The dream is a pair of SET monoblocks (probably 300B type), though I'm worried about not being able to drive the bottom enough.  I listen to a wide array of music from classical and opera to extreme metal, though my wife is decidedly more of a rock person, so I definitely need something that will push those woofers proper. 

Due to lifestyle and logistics, a big piece of my source audio is going to be HQ feeds from my laptop via Bluetooth.  I know, not an ideal source, but until I build my HTPC, it's just going to have to work.  I also need to run optical out from my Sony Bravia (which I can't do right now because the receiver doesn't have optical in and the TV doesn't have analog out).  

Here's the hard part: Right now, I can't really spend more than $1k for the whole shebang.  So I started hunting.

At first I was sniffing around looking for a tube preamp that can handle both Bluetooth and Toslink, but all that seems to be out there are suspiciously cheap Chinese integrated amps that have no pre out for later use.  I also looked at some dedicated DAC's such as the Cambridge Audio DACMagic, that I knew I could pair with a BT-capable tube pre.  But I'm still sketchy about the cheap Chinese kit.  I've heard positive things about Dared, though, and I was thinking their 5BT would be a good foundation alongside the aforementioned DAC, because I could use its power stage for right now, and if I can't stay in the right now budget to get a good pair of monoblocks, then I could wait for a while and buy the right ones later. 

Thoughts? Opinions?  Alternative ideas?

Great.  Keep us posted.  I'm glad to hear you found your speaker soulmate!

Thanks.  I'm excited, really.  I'm already digging how much better the DAC is in this DENON versus going direct to the Sony via Bluetooth.  Getting the Sony completely out of the signal path in exchange for some sweet-sounding glass has me practically drooling with anticipation. 
My understanding is technology has changed so much in 25 years that a 25 year old DAC, while it may be decent today, can be bettered by many options in today's market.  I saw a ML 36 DAC for $1500 used somewhere recently.  

I'll be honest--I'm not entirely sure I know the definitive answer, but if it was me, I'd avoid the 25 year old DAC and focus on something newer--especially if the 25 year old DAC costs $1.5k, as I think today's options at that price or lower would be better. 

I'm curious though.

As someone who witnessed the entire development of "prosumer" digital audio interfaces for recording purposes, I'd 100% agree.  DAC's from 25 years ago just didn't have the bandwidth, error correction, or even the dithering and noise shaping algorithms we have today.  I might be convinced to give a 25-year-old audiophile DAC a spin if I could pick one up at Goodwill for 5 bucks.  But $1500?  Nope.  Not a chance.
