I'm hearing a quiet buzzing when I put my ear within 15" of the speakers.

all components, phono pre, turntable, amp are plugged into a power bar.

Bus doesn't change with input switching or presence of signal, or change of volume except on an open headphone input.

try powering everything down and unplugging the RCA's from the back of the amp and see if it goes away, If so add one source at a time and see if it is the source or RCA cable from the source. 15" from the speakers lots of amps makes a little noise (lots depends on speaker efficiency) but shouldn't be noticeable between songs from your listening position which we hope is further that 15"

If you are still getting this buzz and it is at objectionable levels you need to investigate your power, good audio gear ccan expose power issues you didn't notice before.

Could also be a tube, but usually a hum or hiss, or snap crackle pop during playback and only on one channel, if the buzz gets louder in the next little while then likely a tube.

Cheers,
Ian

Thxdenny for the tips Ian, ill go through it.
I did notice something really interesting though, using the mp3 input to power my cellphone and driving the CD input from the headphone output of same cellphone makes a wonderful ground loop.

oh I can't hear the buzz from the listening position its only barely audible at 15".
I noticed it when I was staring into the amp the way I stare at the fireplace channel at Christmas time, the toasty warm glow, and it sits beside my left speaker so I noticed it.

about the volume thing these speakers crank on about 3/4 volume, wow I'm a bit scared to turn it up any louder.

I have been noticing the sound changes, smoothing out, just waiting for it to fully let go. It seems to be holding tightly to the music right now, can't wait for it to bloom.

So true. I like a full 16 - 24" with your LS3/5As! The detail, balance and soundstage are phenomenal at that distance, provided the grills are off and your head is in the correct spot...
I have settled on 42 - 42 - 42" well away from any walls with the RFS-1 (grills off) for my preferred balance of detail, soundstage and frequency response. My therory is that human hearing is most sensitive in the mid-range, so we can balance the lows and highs to the mid by our distance from the speakers. Not sure if that theory holds water, but it works for me in practice.

Good morning536!

Flipped on the amp, Ella sings Gershwin spinning on wax.

Smooth vocal, her voice is like velvet in her lower register.

There's a steel muted trumpet in there, I remember that sound, etched andpinched but tuneful, nice.

Still sounds a bit crowded but I've played it very little these last days.

Over and over I love the way this amp lets go of the sound, it think the word valve is so appropriate, like water from a tap.

Switched the speakers to 4 ohm outputs, havent noticed a big difference, guess i should wait till it settles in to really expect to be able to atribute a difference to one thing or another.

Going through my little vinyl collection, leaning towards my female jazz tho, Ella Fitzgerald, Della Reese.

Spun some Phil Collins No Jacket Required, Take me Home sounds nice and powerful.

This amp Cranks, its so cool.

Too bad there's not more tubes tho, it almost makes a cool night light!

ill let you all know about the unbox video i made, just waiting to see if its cool with GF to share a link.

Got me thinking...

This sounds so good, smooth, musical.

listening to the Color Purple soundtrack, its nice.

there's so much potential here, I can hear the AT&T and phono pre limiting the system!

I want to put my laptop into it too, see what it can do! I have mediamonkey for high rez playback of Amy Winehouse and Pink Floyd, grr need a good dad, of ya, new releases of 180 gram remasters of Floyd as well so I'd need a good Phono pre and AT&T as well.

this was SUPPOSED to be a simple system, Hah!

well I'm enjoying music again, that's what counts.

is a 5m pair of Ultralink RCA's better than a 24" pair of dollar store rca's?

They're between phono pre and amp?

hmm

So I guess that if MP3's sound better in the treble than my analog rig there's something wrong.

Andrea Bocelli on a memory stick sounds good, and OPEN, there's space around him.

All my vinyl sounds crushed in the upper registers, no space around musicians or instruments.

really thinking about replacing the tt and pre.

any hints?

nice that the amp can really juice these lil boxes, got their woofers moving when I hit the top of the volume dial today with Dire Straits "money for nothing", holy fun!

love jango

Left the amp on last night with some moby station on jango.

8 more hours of run in, does letting the amp idle in the on position contribute to run in, or does it need to be passing signal?

In theory leaving it on does contribute to the burn in time, but IMO the (any) component is designed to reproduce music, so it should have some music playing thru it, like a race car you break them in driving them, not idling in the garage

I'll try again to call you today to see if can sort out your grounding, got swamped yesterday.

Cheers,
Ian
