Better Amp for Cornwall IV's...

I second the previous recommendation to go with tubes. 

You could get a relatively inexpensive ss DAC as there are many good ones available.  Most are Chinese but they sound great and are priced very well.  Check the reviews, including Youtube.

As long as you own the Cornwall IV you can go with any of a variety of low power tube amps. There are many good tube amps available.  Again, check the reviews.  

To start with, check out the Reisong A10 EL34.  You can get these on Amazon for a low price (419) and return it if you don't like it.

Some folks on here will berate Chinese amps but if you're careful in your shopping you cannot beat them for the money.  

At a 102db you could rub two sticks together to make them make a sound.

I would get the purest solid state Class-A single ended amps.
Look at the Nelson Pass Aleph range of beasts, you can get them used also.

Phono stage is not a big issue for me as I seldom spin vinyl and have not bought an LP since 1985.
I have read that the dac in the Denon is just so-so, but personally, I haven't heard enough difference in dacs to get worked up about.
I have the Denon DCD1600NE SACD player and love it!  That's what got me jazzed about the Denon amp; that and it's 4-Ohm power rating and gorgeous looks.  (Yes, I know I'm weird.)  But...I'm concerned about going from my Parasound's big power down to a "mere" 70 8-Ohm Watts.  That, and my Parasound pre does have some really cool features that I hate to give up: bass management, remote tone and balance, volume display, etc.  And it sounds fine to me.  Of course, I'd have to sell the Parasound pair to get the Denon int. and would no doubt still come up a few hundred shy...but day-um it's nice!

For that price you can get a custom made Dennis Had SEP tube amp and one just so happens to be listed on eBay right now!

Also, I can't believe my first post is pointing someone to an amp that I might bid on. Oh well, should save me some money.

You want something really quiet with sensitivity that high. I would suggest a Luxman integrated, or their old MB-3045 amps which are very quiet
