Step-Up or Not to Step-Up: This is the Question


A day ago for a first time I plugged new to me Oracle Delphi MK 1 turntable with moving coil cartridge Denon DL-301 into DK Design integrated hybrid amplifier with build-in phono stage to be amazed how clear and vibrant the sound of vinyl is.
But as I described in my previous post because of low output of MC cartridge I have to dial amp's volume knob all the way to 5 o'clock position to get a decent volume. But that is not a main concern... DK Design has some LOUD function which when turned ON adds some substantial bass to the sound. It is very effective on low volume...to be exact...it functions well with volume knob at position between 8 and 12 o'clock. Anywhere beyond 12 o'clock mark the LOUD function fades out with no effect at 3 o'clock.
Without this LOUD function the bass response is pretty weak. I like it more when it is ON. But since the turntable output is so low I have to use a volume between 12 and 5 o'clock...where the LOUD function stops working.
In order to gain a missing bass I see two possible solutions:
First is to get step-up MC cartridge amp. This will let me use a volume knob between 8 and 12 o'clock where LOUD function works. But this solution will add more circuity and more interconnect cables.
Second solution is to add active sub-woofer and keep using amp at 12-5 o'clock volume knob's position.
I wonder what which solution is more elegant?

You are lucky to have a "Loudness" control on your amp. It is working properly, as you describe it. This is essential if you ever listen at low volume. However, it does require that the regular volume control be in a normal range, not cranked up all the way.

The easy, and completely satisfactory fix is to get a stepup transformer.
Check out the line of Audio Note transformers. They have excellent products. The used vintage Kondo transformers are simply the best but at 3000 used it should be.

check out the AN trannies at:

The ANS2 looks like a candidate and has useful adjustments for cartridges with different specifications.
Get the step up transformer. The loudness button was designed as a bass boost for very low listening levels.

Thanks for your replies! I've just purchased Music Reference RM-4 Pre Preamplifier. It is going to be delivered tomorrow.
I can't wait to try it. Anyone use it? Any comments?
