Modding/tweaking my system


Hi all

I thought I would start this thread almost like a diary.

After living with my system for 12 years, purchased 2nd hand, i find myself wanting to see if i can improve on the sound.

I tried modding a Marantz cd67 player years ago with some success then went too far and wrecked it.

The system is 

Rotel RCD02 cd

Cambridge Audio Dacmagic

RC03pre amp

2 RB03 power amps running as mono blocks

PBC FB1

The first thing I wanted to do was tame the overly bright high end by modding the PMCs to + after years of searching I finally found the crossover layout bought the parts and set about the mods.

1st impressions are the highs are tamed however I have 1 speaker that "sounds" louder than the other, more on that later.

I bought the Dacmagic el-cheapo without the box or instructions. I recently downloaded the instructions and realised the Spdif requires the use of a 75ohm digital cable, I've been using a standard RCA all these years.

The room, HiFi and speaker placement are far from optimal but it is was it is and cannot be changed.

I noted I can feel the CD chassis vibrating with music at reasonable levels so that needs a change.

The overall voicing of the system I would describe as slightly forward with a muddy mid range.

It's the highs and mids I'm looking to resolve.

Hi Spenser Just about, I'm pretty new but did use it to post some pics requested by other members

 

@notdeadyet Here's the link to create your system: https://systems.audiogon.com/ just click CREATE SYSTEM on top right. 

I’m saying that you have many interesting comments about your journey and a system page with photos is a great way to show what you have, let others comment & ask questions about it, and over time as you make changes, we can easily follow your path and learn from it.

One of my favorite ways to learn here is to gain insight into how member’s choices and decision process evolve over time. Occasionally, prospective purchasers might ask for your insights to their situations.

Just a thought for you to get more enjoyment from the forum. Cheers,

Spencer

Just a quick update 

The right hand speaker still seems brighter than the left, but not on all recordings.

I may Have to pop the x-over check the resistor and reflow the solders?

The Sorbothane isolators have arrived today so warming the old girl up and will pop em in later, not expecting any change but a £10 tweak is worth a go.

 

Looking at your setup...I would be inclined to address the placement of your speaker system in your room... along with a readjustment of the room layout to be conducive to a proper setup.
