How to fix my detailed, accurate but BRIGHT system


Hi everyone, I need help. I like my system in that the base is tight, it has good detail, it's dead quiet and it plays well at higher volumes. What I don't like is the mids and highs are way to forward and the system is lacking warmth. I don't feel my system is very musical or engaging. I'd rather not replace my amp and speakers as I think they are a good match and I don't think I can use a tube amp as these speakers are hungry. I have a large room 22'x38' with a 17' ceiling. I have a lot of glass and all tile floors. Room treatment is not an option as this is our main living space. Should I try a tube DAC, Tube Pre., tube Buffer? How do I warm up the sound I'm getting? My system consists of the following.

Rowland Capri Pre.
Butler 2250 SS/Tube amp
PS Audio Digilink 3 Dac with stage 3 mod.
Aerial 7B speakers
Integra DPS-6.7 DVD/SACD
Wadia 170i (files in lossless)

Thank You in advance for your input!

i've had the 7b's for about 4 months, in a near identical environment as the OP. plus the added negative of a hard wood ceiling. i do like my music "forward". some might call it a bit bright. i agree that the 7b's are on the bright side of the line. not by alot but they are there. obviously this trait is worse to have in a listening room like the OP's and mine.

in my system, the highs and mids are pronounced for sure...but smooth imo. i added a velodyn dd12 sub to add a tiny touch of hard bottom end. i spent a ton of time (weeks) with the sub and it's adjustment kit. got it right where *i thought* i wanted it, after alot of work. sub volume is set at 16 on a scale of 100. just the little back-up punch i was looking for. servo is set to max control so it's super tight too.

which brings me to the real reason i jumped into this thread. my old friend Rich commenting above on a negative plateau, quoting John Atkinson. my velodyn kit exposed said platau from about 125-160hz. regardless of where the mic was... it was glaring and impossible to miss on my big screen lol!. looked like 6db or more to me. since the parametric eq in the kit only adjusts too 125hz, i thought it was something i'd have to live with. can't say i noticed it in listening because i enjoyed the sound.

until recently, i had the crossover on the sub set at 60-70 for the most part. during a recent tweek session with the velodyne kit, i inadvertently discovered the crossover could be set as high as 200hz. i would never even think of setting a sub x-over point that high. by accident, i had sent it up to 140. but low and behold, half the platau was gone/dissappeared. i then tried it higher and higher until the entire platau was gone. with the volume set so low...it barely effected the lower frequencies (maybe 1 or 2 db boost max). the x-over is now set at 162 and my FR curve looks incredibly smooth all the way too 200.

looking good on a graph can often be different then sounding good. i immediately tried a bunch of different music and to my surprise....it really did sound "better". a very subtle but important improvement imo. smoother with better depth without being bass heavy. still don't like the idea of having the cross-over set so high but hey...it works and i like the sound better.

as a side note...i also agree with Rich and Tvad regarding amp/speaker synergy. thought the 7b's sounded better with the krells one dealer was using. your comments/observations above would make for a logical explanation (that had never occured to me).

if you're into music on the warm side of things, the 7b's are not a good option imo. they are near perfect for me though. i really like um. my budget was only 2k used when i picked these up. i think i got alot of speaker for the money. will be looking to upgrade in the next year or so but for now.....i'm enjoying them.

Mechans makes a great point about certain IC's. i'm doing IC comparo's as we speak and the Cardas Gold Ref's are in the mix. there is no doubt that these IC's really warm things up, and not by a small margin either. so much so that i don't care for them at this point. (remember that i like things forward or a tad brighter then some). even using krell power, they sounded to warm for me. on the flip side...the acoustic zen silver ref II's sound way too bright with my krell/aerial 7b combo.

a few of you mentioned speaker position. this is something i've been working on too. with help from Rich, i discovered what a big difference this can be. experimented with several new positions in a new location and was shocked to hear how much better everything sounded. have not made the permanent move yet but will very soon

the last comment that rang true to me was that regarding power supply. getting plenty of clean juice to your equipment makes alot of difference imo. kinda pricy but well worth it for me. upgraded to a dedicated 20A line, porter ports, PSA quintet and PSA PW power cords (2 AC-5's and 2 AC-10's). can't tell you which upgrade did the most because each step was very subtle. but together...the whole power supply upgrade did wonders. great depth was the biggest improvement with additional smoothness coming in second. who would-a thought???

being a newbe...none of the above 3 area's of improvement came to my mind naturally. they were all suggestions from various folks around here, kind enough to offer good advice. i thought my system sounded good right when i set it up 4 months ago. can't beleive how much i've learned and how much better it sounds now.(and how much less money i have now =) )

you guys really know your stuff!

cheers
