what's my problem?

here's my scoop:

I have a pair of NHT 2.5i's
rotel rcd 971 transport
MSB link DACIII
Unison Research Unico

I'm not getting the clarity or the air i was hoping for. I picked up the integrated last week, and i figured I'd give it warm up time and some break-in. Not sure what's going on. It HAS started sounding better...smoother...but it just isn't giving me the extension that i want, nor is it giving me the midrange clarity that i expected...

What do you guys think my weak spot is? I'm starting to think it might be the speakers. Perhaps i've simply outgrown the NHT sound. Further, my speakers are a little large for my room which translates to a fairly boomy sound. (The setup sounded better with the smaller NHT 1.3a's that i owned up until recently)

I have heard nothing but good things concerning the Unico, so i'm fairly certain it is not the problem. My front end is decent too (I've heard it in various setups and always sounded good).

Speaker cable is Audioquest type 4 (crap) and interconnects are Monster interlink 400 (also crap). The monster could be one of the causes of the problem.

Also, i have the stock tubes in the unit. Would a change of tubes reap an astonishing change?

HEELLLLPP!!! i'm going crazy!!!

thanks guys,

Steve

Get rid of the MI 400!! You don't have to spend lots of money on cables to significantly improve upon what you're running now. This also includes upgraded power cords. As mentioned, speaker placement tweaking can greatly improve the sound. Also consider speaker stands and equipment stands - Sistrum and Neuance come to mind. Don't underestimate the effect of good stands. When you've attended to these areas, then tube rolling can be very effective. Good luck.

Yes, cables, cables, cables.....
The Audioquest are OK for an inexpensive cable, but the MI400 should go.
How much are you willing to spend, new or used?

At 86 db efficiency and a 3.6 ohm minimum impedance, Im afraid you may be low on juice. The Unico is rated 80wpc for 8 ohm -and- 4 ohm. If the suggestions above dont do the trick you might need to try an amp that is really suited to difficult loads. This might be what you need to "open up" the sound.

get rid of the monster cable interlink 400, it is about the worst interconnect on the planet ... just about anything will sound better .... upgrade the power cord on the amp too ... also give the amp more time to break-in ...

well, the speakers have been pulled out into the room as much as they can be. No room to pull them out any farther. I have another pair of cables that i could try...the MIT Tmax one wire (i think that's its name)...not sure if they're any better. Any suggestions on reasonably priced interconnects that might fit the bill?

Speaker stands are irrelevant (floor standing speakers)

As far as the amp is concerned, I'm not sure what to say. From what i've read, it's capable of running even fairly difficult loads (dealer mentioned this also). Further, it has had such high praise by people in the audio world that I cannot see it being at fault (although i could be gravely mistaken).

Further, despite the ratings of the NHT's, I have been told (by the dealer) that they are an easy drive. At one point, he tried to sell me an Alchemist Nexus integrated (i think it's rated at 35w/ch). He claimed that this would drive them properly. I would hate to have to ditch the amp as it's brand new (and was tough to find in my area)

At one point, i had a Roksan Kandy mkIII rated at 120w/ch driving them... didn't do as good a job as the Unico. Would the Simaudio I 5 fare any better? Should I go with separates? (ie higher power amp/ separate preamp)

should i keep the amp and find some smaller speakers that might match up more synergistically with the Unico?

After so many years of playing with audio equipment, I seem to have lost my way...(and my mind)

i'm in audio hell.
