Please recommend speakers

How about Emotiva T1+ floor standers for $799 a pair or B1+ bookshelves for $299 ? I have original T1 in my dedicated stereo room paired with turntable and it sounds pretty good. I also have T2 and C2 in my home theater room that’s put out some good amount of detailed and forceful sound, but requires some EQ with minidsp due to room dimensions.

I have a pair of the Kef Q350's that the OP mentions.

They are great speakers with nice, clear mids and highs and surprisingly good bass.

Part of that good bass comes from the rear port, which would not fare well in a bookshelf. You could try plugging the port and thwarting the design intent...but good luck with that. 

The front ported Q100's are designed for wall mounting or shelves, but you'll sacrifice bass and midrange. Perhaps a pair of small subs that can reach fairly high can help, but they would surpass your budget.

Just build a BIG BOOK SHELF

Even though Maggies need power I heard the DA9 on a pair of LRS and it sounded very good but it was a smallish room but Maggies do sound alive with powerful amps.

I have a lovely pair of KEF 100s I got for about 500. But my room was only 15 by 12.   But the sound is pretty darn good.  Won't beat a 30k speaker but it shouldn't be expected to 

A pair of KEF 100s are surprisingly good at lower levels. They are discontinued but have seen them available on sites. I like them better than my KEF 350.  They are on the warm side.  I also have Dali, Paradigm,  Jamo, Klipsch, wharfedale and others,  so my biases are limited.   The klipsch are lower end and in a warehouse and provide a good sound in about 3500 square feet,  so far from ideal listening but they are very efficient.  Low end is their weakness.  But depending on room size I would go with 100s because my ears  match their sound.  So check out gear with your ears. Because we all are unique.  

On the lower end of scale, wharefdale diamond 220's would work well on a bookshelf. They have down firing bass ports. A more expensive option would be the sonus Faber Lumina 1. They also have a bass port in the plinth, similar to the 220's but more forward firing. I've seen pictures of both speakers on or in actual bookshelves. 

Return or sell the SMSL DA-9 amp and just run your DAC into powered studio monitors. I would recommend Adam or RCF.
