More sound reports on the DL-110 please Vince !!!
I apologize in advance for being wordy.

I have low gain with my BOZ-J. I raised the voltage from 18v to 26v on the BOZ-J and still have low gain on the phono side. From my CDP, gain is much better. There is suppose to be a "sweep spot" with certain Idss 2sk170BL volt/current combinations, but I found that the sound is very relaxing yet is able to drive the bi-amped system better.

However, with DL-110, there is no change. Gain is very low, but that maybe because I have not removed the 150 ohm load resistor yet. Yesteday I ordered a few DIP switches and several Vishay 1% resistors to setup a parallel switching system. Did the same for cap values from 100pF to 330pF.
Once I have the parts, it should not take me long to build a small board for the switching setup. I'm hoping the correct value resistor will help to improve the gain somewhat. I'm investigating building a new preamp, but I would rather not. Will try to insert my BOZ and BOSOZ preamps in the chain to see if there is improved gain over all.

I can tell you this, and this is an educated guess- the DL-110 is a great value for a HOMC cart. No doubt. Even with the problems I'm having, I can tell that if properly setup, it will perform very well and make great sound.
I believe the stock DL-110 is more quiet that my modified DL-103R with aluminum body and ruby cantilever.

One other thing and this may not matter, but the DL-110 is much prettier in person than in photos. You'll see what I mean, if you haven't seen one in person. What I'm trying to say is don't let the price and pictures fool you.
It's a performer.

Vince

Default Step-up Transformers and MC

This is a good read on the subject of step-up transfos, MC and impedance.
Much easier to understand, for me anyway.

I can see why my current setup can be balling things up!

Nice work Vince.

Have been penning a loading-switch arrangement here myself.

It's based on series & parallel, and, parallel + series, permutations with 4x 900 Ohm wire-wound Ayrton-Perry styleee resistors; and 1x 47K Ohms 'flat-planar thick-film' resistor.
It gives 10 loadings, between 225 Ohms & 3600 Ohms + 1 loading of 47K Ohms...
...could be pretty cool for change-ability.
All with only 5 resistors & a rotary switch.
Simples !

Pleased to hear the Denon is sounding good...
...guess they wouldn't have been making it since 1982, if it didn't.
Denon DL-160, strangely 'Discontinued' ...Mmmm.
Was gonna go for that one...
...but not much good, if I can't buy a replacement easily, if needed.
So Denon DL-110 @ Space Egg it is !
Waiting for 'grey NYC import' !

Cheers.

Si.

Hi Si,

Did a bit of listening last night after I removed the 150 ohm resistor.
Left in the 47k and did not add a 1k resistor because I'm waiting to build the load switching unit. Parts arriving soon. There was a bit more gain after removing the 150R.

Like with any cart, the DL-110 required about 2 sides of a record to warm up.
At about 3/4 of the second side, everything just opened up. More depth, detail sound stage was better and has nice extension in the highs. Midrange is nice too.
Nothing about the playback with the DL-110 is harsh. Over all it is a bit more veiled compared to the 103R, but is still very enjoyable. Maybe it will change again with 1kR.

Vince

Hi Vince

Nice !

From what I gather around 1K is def. in the ball-park.

Way to go...on the new preamp here...
...your pretty sorted with the Pearl I'm sure.

Cheers

Si.

Hi again Vince

What do rec. on the capacitance then ?
Don't think capacitance is going to affect the DL-110 much anyhow...
...more MM balance stuff.

Might fiddle with my old preamp a bit.
I have a strange feeling, it might have too much & I never realised ( used with MM ).

How many & what cap settings are you thinking of ?
Is that to run other carts, eg. MM's with ?

Cheers

Si.

Adding the capacitance switching for both MM and MC, if needed. Might not need it, but it doesn't hurt to check. Just my opinion. I'm adding 100pF to 330pF switching capability.

Different people say different things about capacitance on MC. Definately need it adjusted on MM. Read the Pass Labs brochour for the XP-25 and 15 today.
My friend with the AR phono...well he switched. No pun intended. The PDF says MC don't always need more or less capacitance adjustments, but you should check anyway because it can change the tonal balance. It's a matter of perference. YMMV. You should read the XP-25 and 15 PDFs. Good info.

Like I said when I started the thread, there are a ton of carts out there. Why limit yourself?

Vince

Apparently, the schematic of the Pearl I PS is incorrect.
I decided to implement a simplified F4/F5 PS. Took 5 minutes to change and made all the difference. Now have plenty of gain.

With the DL-110 only the 55db gain is necessary. When switched to the CDP, the gain is the same. You know, that whole thing where one has to crank up the gain when switching to phono and pray to remember to lower the line stage when going back to CDP. Didn't have that problem.

Next, you have to take what I say with a grain of salt because I have a mid-fi turntable and tonearm- the AR "The Turntable" and Linn Basik vx. However, I think this price range cart is made for this type setup. Also, I'm still using the 47k load. Won't have the load switching system in until this weekend or next week.

The character of the 110 hasn't changed other than to prove it has hefty output.
I don't find that it really sparkles in the highs but its not absent either. Same for the mids.
It can present a whole lot of bass when its in the source material.

The best sound I pulled from the 110 was by using the extra weight plate for the cart.
Without it, there was a hi freq breakup on loud passages. The added weight allowed for the tonearm weight to be set further from the pivot point of the arm. I believe that this may have helped reduce some resonance in the arm, stopping the hi-freq breakup. In addition to the plate, a slightly higher than normal VTA provided more detail in the mid range, especially with a female voice.

I now have a problem with the sound being to loose. Like an under dampened ported speaker box. Its causing the bass, and in fact, the entire range to sound muddy. Could be due to sub-chassis springs or motor speed or both. Could be due to weak, hollow plinth also. Added cones as feet, but helped very little over all.

That's it for now. Won't report again until I do more with the load switching.

All the best,

Vince

Check the bounce on your ar.
And mat and record weight could help.
I use a bren and cork/lead mat on my ar's.

Just as info.... A well tuned stock AR could do carts into the 1K$ justice. IMO.

Who can post test reports about vintage and new moving coil cartridges, where was check the frequency response with test record (pink noise) and with various loads ??
