Preamp vs DAC vs Streamer

To be clear on why I really needed room correction or at least low & high pass was I was getting +16db spikes at 32hz from my R11’s! That cannot be adjusted out. Never was a problem before as my crossover point was much higher than that. But now running full range… major problem. And my room, based on windows is not conducive to bass management. 
Luckily plugging the rear ports on the R11’s alleviated the problem. I am hoping with the new tubes, and the bass management, I have in place, I can avoid the miniDSP, as I prefer to stay analog. Thanks

"+16db spikes at 32hz" Yeah, that's a problem! At least you know the KEF's can dig deep..I am guessing though that such an issue would be from a movie soundtrack rather than a musical track.

You may not really need the subwoofer especially if you don't listen to music that dips below 30hz. I had used a sub for a few years but realized it was overkill and listening without one put more emphasis on the midrange frequencies - which is where most of the music resides. Doesn't help that I am getting older and my hearing is fading. 

Two ports on each speaker that houses 4- 6 1/2" woofers is fairly unique, especially a port that high up on the speaker. Throw windows and a sub into the mix and I see your dilemma and a need for measurements/data. To add to that scenario, the Brimar tubes are likely to add more bass. Good luck with that! ;)

As for the Rogue, I typically turn it on a couple of hours before I listen. My understanding is that a preamp with tubes can be left on at all times, but not the case with an amplifier. My DAC is on all the time, as Schiit suggests to do so as it will better the results. 

Please be sure to share your thoughts on the tonal changes of the Brimar tubes once you have had some time with them as they are on my want list.

The 16db spike was while running Audyssey from my Marantz using HT pass trough on the Rogue. I was using Audyssey to help adjust my subwoofer crossover points. Turned out to be a great idea revealing my problem. Again luckily, plugging the ports provides a very flat left… still some issues on the right (nearer the room corner).

I may be able to do room treatments on that side as there is a clear wall behind the right speaker.
Will let you know on the new tubes. 
BTW, I am old also, but my hearing aids are excellent. Thanks!

My NOS Brimar’s arrived yesterday. They sound spectacular! Lows are crisp, no longer muddy, mids, highs are clear. They sound silky. Overall outstanding results. Thank you for recommending the RP-1 and the tube replacement. Very happy!

My new DAC arrives tomorrow. Look forward to getting my digital side close to vinyl. Thanks again!
