McCormack DNA1 options

I own a McCormack DNA1 and a TCL-1 preamp and Merlin TMS-SE monitors[which I really like].

While I have been very pleased with this combo I do find
it, at times, a tad forwards, somewhat grainy, and harsh/tizzy esp. at the higher frequencies.

I listen to a wide range of music, esp acoustic and vocals.
I'm in a position to upgrade and I was wondering how best to invest.

A) Get the DNA1 upgraded
B) Purchase a tube preamp
C) other ?

Thanks for your input

Thanks for all the pointers.
The discussion of cableing was very astute (you guys are good !). I should have qualified my description of the
system by stating that 97% of the time I am very satisfied.
This system continues to blow me away. It's really impressive. Here are some other details.

DNA-1 (non-delux)
Digitial source Rotel 951
Monster Power HTS 2500 MkII
Cables and IC. --well these are kinda a hodgepod.
Electrical power etc. very old house with non-dedicated
outlets.
Small sized room, with lots of acoustic treatments
(this was a huge improvement.

So perhaps I'll work on some cableing...
and then get the Rev.A and a tube pre....

Onwards and upwards.

Just a note on the tube preamp option. I have a DNA-0.5 Deluxe and recently bought a used BAT VK-3i to replace my previous ss preamp. The VK-3i is a wonderful piece of gear but the combination produces hiss that is clearly audible from my listening position. Thinking it might need to be retubed, I spoke with Kevin at Upscale Audio and he seemed to think the problem is that the amp is too sensitive. Victor at BAT also thought that might be the problem. Sure enough, I was able to hook up another amp and the hiss decreased dramatically. Now I have a dilemma since I really like both pieces. What I'd really like is a VK-200 but that's another story. I assume that the DNA's high sensitivity is due to Steve's preference for passive preamps but I don't know that for sure.

Good luck.

I matched my DNA 2 with an Atmasphere mp 3 pre amp and the results have been astounding compared to my previous line stage and the 7 other auditioned pre amps. If you have a dealer near by give it a listen.

Check your power. I have a DNA-2 with a digital front end. I noticed some of the characteristics that your describe before I went in and put in decient power conditioning.

Not sure if the DNA-225 I have will compare in combination with preamps in the same fashion as your 0.5 Deluxe, but I can tell you that the DNA-225 paired with a Kora Eclipse (Siemens goldpin tubes) produces absolute "blackness". Might be worth an audition for you.
