New Receiver HK AVR-7300 / advice and opinoins please

[gall34]

I have just upgraded my Harman Kardon 5550 to an AVR-7300.

What do you think is the optimum burn in time and are there any 'quick' ways of doing so.

I am relatively a novice in the HT area but I really love my music and only like it played on quality equipment. I have noticed though the better my components have gotton the more they find faults in the recordings, is this a common problem?

The difference in picture quality is outstanding with the 7300 but at the moment although the power differnce is huge the sound is not that much better than my 5550, I imagine this is due to the receiver needing to be run in. I have noticed the bass is more powerful and tighter which is great.

If anyone has any experience with this receiver and could give me some advice to the optimum settings, etc I would really appreciate it.

The rest of my system comprises of:

Sony X-7ESD CD player
Luxman D-105u Hybrid CD player - haven't decided yet which one to use with this system
Harman Kardon TD-4400 Cassette Player
Nakamichi DVD-10s
Loewe Aventos CTV
Pure acoustics Dream 77F fronts
B&W CDM 1NT rears
B&W CDM CNT centre - still chasing the 9NT's
Pure Acoustics PL-W12 subs (2 of)

thanks.

How about 0 hrs It was ready when the box was opened.

I bet the faults were audible before but it is ancient history by now.


but at the moment although the power differnce is huge the sound is not that much better than my 5550,


That is because you may still have the same old speakers and same acoustics in the listening room, right? Speakers and the acoustics are the major acoustic issues, not the receivers.

I imagine this is due to the receiver needing to be run in.

Sorry to disappoint but this imagining is not real.

Why do you say there is no burn in time, when i purchased the 5550 it took around 2mths before I was happy with it, and it wasn't my imagination or my ears getting used to the sound as I have very good ears for music.

The dealer I purchased the receiver from and The Harman subsiduary have both told me I need to run it in.

I agree the faults were probably always in the recording and that was my point, is it normal for better quality equipment to make these more apparent as when I was running a basic system and playing the same recodings they were not noticable.

Yes my speakers and room are the same, but I do know when I first upgraded from my onkyo to the 5550 there was a huge difference.

maybe.. but i have never heard of a receiver having a break in period.
or any type of amp needing to be broken in. id be surprised it it was true.

i think they were lying to you..

Sorry to have shocked you by this information. At times truth hurts, as many have told me this.

How do you know it was not your imagination? How did you test it? You did test this, didn't you? If not, I am at a loss to help.

The dealer I purchased the receiver from and The Harman subsiduary have both told me I need to run it in.

Oh, the dealer told you this. They have no biases, financial gains in selling to you and make sure you will keep it. This is called marketing. Call them on the carpet. Ask for bankable evidence, that is credible evidence, not customer feedback, testimonials, etc.

This is testable as well, you agree?

The HK website has alot of articles on the science of sound and although I can't say I remember every single one of them, I can say that I am 99% positive that NONE of them recommends a 'break-in' period.

Ive got the 7200 and it is a beast! I was never told of the break in time and I dealt directly with the manufacturer. My guess is the shop of purchase wants you to forget that you could bring it back. The sound and picture quality is awesome on these products. you should be very happy with your prooduct.

the speakers and room layout would have have a big impact on the volume. Your quality of sound should be fine (in my opinion). If your not happy with the volume level, maybe think about more efficiant speakers. The 7300 should be able to fill a mediun size room with as much volume as you will ever need! If you need more...think of adding an extermnal amp (i dont think you will need to)

You will notice a lot more detail in music from when you listened before. That is normal with better equiptment. The downside is you will MORE notice the flaws in the recordings. The upside is everything else!

Have fun!

Amp power

I have just upgraded my Harman Kardon 5550 to an AVR-7300.

The difference in picture quality is outstanding with the 7300 but at the moment although the power differnce is huge the sound is not that much better than my 5550, I imagine this is due to the receiver needing to be run in. I have noticed the bass is more powerful and tighter which is great.

Concerning the power upgread on your new receiver, doubling the amplifier power will only produce a 3dB increase in volume which would sound slightly louder. To sound twice as loud, you would need 10 times the amp power. With the upgrade, it is likely that you got a bigger power supply and amp with more headroom and maybe a cleaner pre-amp stage.

Also, note, for the best HT experience, your speakers should be timber matched, especially the fronts and center channel. The easier way to achieve this is to buy them from the same manufactuer and same line of speakers.

Enjoy your new gear
