What did you do to your stereo rig today?

Mike Reeter

Took the rig apart today to perform an annual room cleaning. Time to clean wire connections and whatnot also

Solid state amplifiers (or receivers) draw very little current (more to the point, they consume very little power) at idle.

Unless it is Class A.

That is absolutely true: Class A (power) amplifiers are running essentially "flat out" at all times, whether tubed or solid state.

Doing some serious A/B'ing between my B&K M200's and my Belles 350a Reference... Again.
Update. Rolland at Hi-Tech Audio told me to use a 2 prong adapter on my power cable for my Belles. Much better!

Oh those B&K must sound terrible against the Belles. You should probably just sell the M200s to me.

just listened to it for hours today, no work done!

On & off over the past 2 weeks messed w/an RTA and its mic at preferred seating monitoring just my LR RTi A7 towers

This first image is the un-tweaked in-room FR. Pink noise from a phone app, LP’d ~3K. I turned off subs & verified DSP was disabled....


...and the after. LP’d @ 10Khz, after DSP W/subs.


During several sessions of fiddling & tweaking I learned and/or discovered a few things:
a. the spec’d FR is only the roughest suggestion of in-room FR.
b. In-room will surprise you
b. by the first “graph” you see a substantial hump @ 35hz. Polk specs the F3 at 35hz.
c. the tweeters* were “flipped”. I noticed a notch right at XO frequency between them* and the mids. I flipped first one channel, then the other seeing the notch disappear.

Following some tips from a friend:
a.I smoothed out the FR low end by “carving” the peaks - no boosted frequencies.
b. I performed BSC w/a 3dB sloped shelving cut @ 576hz followed by turning up the mid a few dB

I’m delighted the final in-room system F3 is below 25hz

During the last session I did some prelim on my CSi A6 center. I determined the tweeter has issues - blown I think. Next chance I’m gonna look at the RTi A3 surrounds and their subs.

Cheers

Ha! I seriously can't decide which one I'd part with. Since I don't have a gun to my head I'll probably just put one of them back in the spare bedroom eventually.

Today I swapped my Yaqin mc100b tube integrated for the Mc mono's just to change things up a bit for a few days. It should be quite a change going from 1200+wpc down to 45wpc in triode mode.
My guess is the 1.2tl's aren't going to be as happy now with the big reduction in current

Gosh I'd love to hear both to be honest.

You're more than welcome to stop by if you're ever in the area.

Skipped the preamp and plugged the Lumin directly in to the amp. Yes please, more of this!

This isn’t great for the TT since both can’t be plugged in at the same time. Meaning I would be connecting and disconnecting ICs to change source and believe I would need a phono pre like Gram Slee Ascension.

That said I’m going to have an in home Demo of the RP-7 this weekend.

I really don’t know which way this is going to go. My Logic says less is more and having a preamp can only get in the way but who knows, it could add that something special.

I’m not a betting man but any thoughts on how it ends?

Karma after a decision is made! Wish me luck!

Try the Yaqin in ultralinear mode as well...looking forward to your impressions.

@phipiper10 bet it’ll end with static when using the remote @daboyz

I have been ignoring mine. But I got a bunch of iFi noise doohickeys to test when I have the presence of mind to check out.

Well I took My 99 Magnum out of the chain so if my phone, as the current remote adds static, I will blame @daboyz !

I’m looking forward to your thoughts....

I’m not unhappy in the slightest with my Cary 05 preamp. However, I’ve often wondered what the RP-7 (or 9) would bring to the table when paired with my Rogue M-180 monos.
btw, I just upgraded to the Dark mod

Which LUMIN do you have?

TIA

I have the lumin T2. Also picked up Primaluna Evo 400 preamp, just before getting the RP-7 (no RP-9 at my dealer) this afternoon.

Primaluna is up first and just casual listening right now. I'll do a little write up when done.

Never heard them but Those Apollo Darks were on my wish list. Think I'd be afraid of those, they are beasts!

Yesterday, performed a more comprehensive cleaning of equipment and stand than usual. And...

...tweaked the surrounds and their subs - much more challenging than the LRs and their subs. I regret no RTA image to post. The tweaked FR is smoother than before but it needs more than I had time allowed.

“The Dark Knight Rises” sounding MANY times better than in the theatre @ PCB years ago. In PCB theater, ANY gun fire hurt my ears so much I had to anticipate to put my fingers in my ears. My system - NO PROBLEM!

Put my B&K monos in the closet. The upgrade I performed on the Belles 350a Reference is taking a lot longer to break in than expected but I'm really liking what I hear. The things I liked more about the B&K's are becoming less of a difference now. The Belles takes up less space too.

Nice of you to give Tom Cruise a set of amps to build around...

I had a pair of Mullard cv4003's that I thought were noisy since last I played them was a few years back when I had a Belles 21a preamp. Well something told me to try them in my Mastersound Compact 845 integrated amp. They were dead quiet and the best sound I have heard from the Mastersound, not to mention that it saved me $300 as that is what they are going for a pair now.

I’ve been running this guy in my rig the last few days. AVA FET Valve 600R Hybrid. Sounds just plain excellent to my ears.

I’m wondering what some NOS Mullards or similar in the input stage might do for the sound.

maxward

Almost pulled the trigger on that one several years ago. Glad you are liking it!

pitdogg2

What tubes?

Gerres26

Its almost brand spankin new and still has the stock JJ 12at7 tubes in it. Just when I thought I would stay away from tubes , they drag me right back in. It sounds great as is but it’s been my experience with tube rolling there is a chance to be even better...guess it’s time to look for a deal on some nice sounding NOS replacements.

nooshinjohn

That is a serious toroid...

I have this tube in my DAC, it provides the 'Secret Sauce'. In the right application, it's one of the best.

Warming up the HT for the big game, so nothing major just getting ready.
