New Preamp or go Integrated

@vette5451,  to follow up on what @soix just posted, if you do start thinking about CODA, and want to go integrated — I just did (CSiB V2) b/c i had space and weight constraints — you might want to reach out to Ravi  https://www.audiogon.com/listings/lisbge7c-holiday-special-coda-sensibly-priced-reference-performance-amplifiers-solid-state. He’s an authorized dealer/manufacturer partner and often has good pricing available on new units. Probably not $5K or less, but a lot less the MSRP.

(I had the Parasound Halo P5 and A21 (not the + like you have) for many years, and I do think the CODA is more accurate while being no less musical. The v2 is 250 wpc at 8 ohms and doubles at 4; Class A for 12 watts at 8 ohms; a very nice sounding, very powerfull unit.)

There is a lot of good commentary about CODA on here and elsewhere on the interwebz.

Happy hunting and good luck to you.

I have two homes, in one I have separates, in the other I have an integrated amp.  FWIW, it is just two different ways to skin the cat.  Since you already have separates, it kind of makes sense to look for just a preamp as @kennymacc has suggested.  I also agree with @soix that you need to put some hours on your speakers before making any big changes.  I also agree with him that thinking longer term, you could benefit from subs.  Without doubt you would hear more difference by doing these two things than you would from the difference between separate vs integrated amps and preamps no matter which ones were under consideration. 

I have the 252. I really like it.
