Stereo preamp upgrade

Hello! I was hoping to get some advice from the last true audiophiles. Some time ago I purchased my first separates system after my college roommate got me into home audio. The system consists of a Rotel RC-1070 preamp, Rotel RB-1080 amp, Paradigm Studio Monitor 100 v2's, with Tara Labs and AQ power cords and IC's. Something isn't "right" with my system. I'm pretty sure it's my preamp.

I've had a great opportunity to hear a LOT of equipment, since my aforementioned roommate was a repair tech at a local hi-fi shop. He would bring really nice gear home constantly and we would audition his repair work, not to mention the equipment at the store. He had the same speakers as I have now so I know how they can sound.

The Rotel preamp is decent but the bass is not 'warm & soothing,' but has more of a raw feel. It seems to be tight and controlled, likely due to the amp, but it just doesn't seem to have that 'earthy' feel if that makes sense. The soundstage could be improved. It seems wide enough, given my crappy apartment acoustics, but the depth just isn't there. There is no 3rd dimension. Tonality is great. It's not dark or overly bright.

So, I'm looking for a recommendation for a new preamp. I only want a stereo preamp. I would love to have one with a optical input, but I suppose I could get a DAC instead (that's a whole 'nother subject), as I've begun to use a computer to play .flac's. I'm looking to spend around $500 and don't mind if it's used. I've considered the Adcom GFP-750 as I know it's a solid unit, but I don't have much experience in preamps.

What would you do in my position? Music comes first.

The Parasound Halo P3 sells regularly on this site for around $500, it should present a different sonic character than the Rotel. I have not heard your pre-amp, but I use the Halo with an RB-1080 to push MA BX5s, and I'm fairly happy.
Your studio 100s are much nicer than the BX5s of course, they are on my "possible upgrade" list. In the Stereophile review of the 100s, John Atkinson states: "The impedance, however, drops below 4 ohms between 55Hz and 210Hz, with a minimum value of 3 ohms at 90Hz"..."A good 4 ohm-rated amplifier should be used with the speaker."
The RB-1080 is *not* a good 4 ohm amplifier. Something more along the lines of a McCormack DNA 1 might push your studios better, but these amps run about $700-$800 used. I'd suggest a new amp, not a new pre...

The Parasound is a solid recommendation. You won't find better than a Muse model 3 at that price point, I've seen them around $600. Be aware this is not a model 3 signature. The old Sumo Athena is surprisingly nice, probably around $300. The Adcom you mentioned is a good piece also, might be a bit detailed and edgy with the Rotel, But all of these will give you noticeably better performance than your RC-1070. I hope this helps,

What you want will have to be a future purchase, I'm afraid. The kind of sound you seem to want will come from some decent tube power amps. A lot of people start with a tubed pre. I found in my journey that it really wasn't the keys to the kingdom. If you want to go that tubed pre route, however, I heartily recommend a tubed pre by the AES division of Cary. The model is the AE-3, which sells used for less than $500 in certain iterations and rarely for more.
Unfortunately Upscale Audio is the last dealer Cary makes these pre amps for new. They put nice paint on it and filled it with options. This overstuffed version with stock tubes is $1200. That is not a lot for a good preamp but you will want to roll the tubes etc. It's really too bad that there is no base model to buy. Oh well!

One of the reasons I went with the Parasound is because of the remote. A remote is an absolute must for me in a pre-amp, as my listening sessions occur for hours on end while working behind a desk at home. This severely limited my options when hunting for an affordable pre-amp, otherwise I might have gone with another unit. If a remote is similarly important to you, make sure you check that box during your investigations.

Thanks for your honest advice. Speaking of a tube pre, I happen to have a Little Dot MKIV that I bought on a whim to tinker with that needs new tubes. It sounded fabulous at the time, but one of the driver tubes was shot so it didn't sound its best. I think I'll go tube hunting and see what I can come up with and give it a go. It's always fun to experiment and see what becomes of it.

The Rotel pre isn't a bad unit at all, but if it's going to cost over a grand to get into the next 'class,' I'll just save more money and explore my options.

Speaking of bass, I have an Electron Kinetics Eagle 2 that when it worked, had really nice control over the 100's. I can't recall hearing anything like it for the price. Maybe I'll send it off to get fixed.
